RF-571 O-X95 SERIES SAFETY SUMMARY

SAFETY SUMMARY 1. INTRODUCTION All operators and maintenance personnel must observe the following safety precautions during operation and maintenance of this equipment. Specific warnings and cautions are provided in the manual and at the end of this Safety Summary. Warnings, Cautions, and Notes appear before various steps in the manual and will be used as follows:

2.

0

WARNING

- Used when injury or death to personnel and damage to equipment is possible

0

CAUTION

- Used when there is a possibility of damage to equipment

0

NOTE

- Used to alert personnel to a condition that requires emphasis

PERSONNEL

AND EQUIPMENT

SAFETY

Basic safety precautions consider factors involved in protecting personnel from injury or death. Electrical, mechanical, ElectroMagnetic Radiation (EMR), material, or chemical hazards are the most common types of hazards found in electronic equipment. The following are types of hazards that may exist: ELECTRICAL

- Hazardous voltage and current levels may exist throughout the equipment. Contact with these hazards could cause electrocution, electrical shock, burns, or injury due to involuntary reflexes of the body.

MECHANICAL

- Mechanical hazards are created when heavy assemblies and components must be removed and replaced. Moving parts (such as fan blades) and hot surfaces are potential mechanical hazards.

THERMAL

- Burn hazards may exist in the equipment that could cause personal injuries and/or serious equipment damage. Internal surfaces of the equipment may be in excess of 65°C the point at which personnel could be burned. Extreme caution should be used when working with any hot assemblies (for example, power supply or power amplifier assemblies). Physical injury or damage may result to personnel and/or equipment as a result of a reflex action to a burn.

CHEMICAL

-

-

EMR 3. OPERATIONAL

Chemicals or materials used for servicing the equipment may present potential hazards. Many chemical agents, such as cleaners and solvents, may be toxic, volatile, or flammable. If used incorrectly, these agents can cause injury or death. Overexposure to electromagnetic radiation results from amplified radio frequencies which may produce a health hazard.

AND MAINTENANCE

SAFETY GUIDELINES

Good safety discipline is critical to prevent injury to personnel. All other safety measures are useless if personnel do not observe the safety precautions and do not follow safety disciplines. Once aware of a hazard, personnel should ensure that all other personnel are aware of the hazard. The following basic safety disciplines are stressed: a.

Read a procedure entirely before performing it. Personnel must always perform each assigned task in a safe manner.

b.

Prior to applying equipment power after maintenance, personnel must ensure that all unsecured hand tools and test equipment are disconnected from the serviced/maintained equipment and properly stored. ...

XIII

RF-5710-X95 SERIES SAFETY SUMMARY

ai3 HARRIS RF COMMUNICATIONS

C.

Power to the equipment must be removed before a piece of equipment is removed.

d.

Extreme care must be used when adjusting or working on operating equipment. Voltages in excess of 70 V or current sources in excess of 25 A are covered with barriers. Barriers include warning information about the hazard encountered upon barrier removal.

e.

Personnel must react when someone is being electrically shocked. Perform the following steps: 1.

Shut off power.

2.

Call for help.

3.

Administer first aid if qualified.

Under no circumstances should a person come directly in contact with the body unless the power has been removed. When immediate removal of the power is not possible, personnel must use a non-conductive material to try to jolt or pry the body away from the point of shock. f.

Personnel should work with one hand whenever possible to prevent electrical current from passing through vital organs of the body. In addition, personnel must never work alone. Someone must be available in the immediate area to render emergency first aid, if necessary. Lifting can cause injury. Items weighing more than 37 pounds must be lifted by two or more people.

h.

Some electrolytic capacitors contain aluminum oxide or tantalum. If connected incorrectly, the capacitor will explode when power is applied. Extreme care must be used when replacing and connecting these capacitors. The capacitor terminals must always be connected using the correct polarity: positive to positive and negative to negative.

The next section contains general safety precautions not directly related to specific procedures or equipment. These precautions are oriented toward the maintenance technician. However, all personnel must understand and apply these precautions during the many phases of operation and maintenance of the equipment. The following precautions must be observed:

DO NOT SERVICE EQUIPMENTALONE Never work on electrical equipment unless another person familiar with the operation and hazards of the equipment is near. When the maintenance technician is aided by operators, ensure that operators are aware of the hazards.

GROUNDING Always ensure that all equipment and assemblies are properly grounded when operating or servicing.

TURN OFF POWER AND GROUND CAPACITORS Whenever possible, power to equipment should be turned off before beginning work on the equipment. Be sure to ground all capacitors that are potentially dangerous.

KEEP AWAY FROM LIVE CIRCUITS Operators and maintainers must observe all safety regulations at all times. Do not change components or make adjustments inside equipment with a high voltage supply on unless required by the procedure. Under certain conditions, dangerous potentials may exist in circuits with power controls off, due to charges retained by capacitors. xiv

HARRIS t#l RF COMMUNICATIONS

RF-571 O-X95 SERIES SAFETY SUMMARY

-

DO NOT BYPASS INTERLOCKS Do not bypass any interlocks unnecessarily. If it is necessary to employ an interlock bypass for equipment servicing, use extreme care not to come in contact with hazardous voltages.

USE CARE HANDLING HEAVY EQUIPMENT Never attempt to lift large assemblies or equipment without knowing their weight. Use enough personnel or a mechanical lifting device to properly handle the item without causing personal injury.

HEED WARNINGS AND CAUTIONS Specific warnings and cautions are provided to ensure the safety and protection of personnel and equipment. Be familiar with and strictly follow all warnings and cautions on the equipment and in technical manuals.

PROTECTIVE EYEWEAR All personnel must wear protective eyewear when servicing or maintaining equipment. Protective eyewear must be worn at all times when using tools. 4.

PROTECTION

OF STATIC-SENSITIVE

DEVICES

Diode input-protection is provided on all Complementary-Metal-Oxide-Semiconductor (CMOS) devices. This protection is designed to guard against adverse electrical conditions such as electrostatic discharge. Although most static-sensitive devices contain protective circuitry, several precautionary steps should be taken to avoid the application of potentially damaging voltages to the inputs of the device. To protect static-sensitive devices from damage, the following precautions should be observed. a.

Keep all static-sensitive devices in their protective packaging until needed. This packaging is conductive and should provide adequate protection for the device. Storing or transporting these devices in conventional plastic containers could be destructive to the device.

b.

Disconnect power prior to insertion or extraction of these devices. This also applies to Printed Wiring Boards (PWBs) containing such devices.

C.

Double check test equipment voltages and polarities prior to conducting any tests.

d.

Avoid contact with the leads of the device. The component should always be handled carefully by the ends or side opposite the leads.

e.

Avoid contact between PWB circuits or component leads and synthetic clothing.

f.

Use only soldering irons and tools that are properly grounded. Ungrounded soldering tips or tools can destroy these devices. SOLDERING GUNS MUST NEVER BE USED.

DESCRIPTION

The Harris RF-5710-X95 HF Modem, shown in Figure l-l, has the ability to generate five HF waveforms (see Operation section for available waveforms) using the same hardware. Each waveform is selectable from front panel controls and the current mode of operation is shown on the Liquid Crystal Display (LCD). The modem allows both half-duplex operation and full-duplex operation in most modes of operation, except data rates of 4800 bits per second (bps) when only half-duplex operation is supported. A flexible, programmable interface ensures compatibility with a wide range of data and radio equipment. The versatility and speed of the modem make it suitable for a variety of applications, including: Narrowband Secure Voice High-Speed Burst Data Digital Facsimile Slow-Scan Television HF, Microwave, Land-Line Narrowband Satellite Figure l-2 shows possible applications of the modem in an integrated communications system, including transmission of high-speed data, digital facsimile, or narrowband secure voice. It can support either synchronous or asynchronous data terminal equipment. The architecture of the modem is based on the TMS320C51 and DSP56156 families of Digital Signal Processors (DSPs) and the 8OC186 microprocessor. The unit is a general purpose signal processor with input/output capabilities, and provides for future waveform/option expansion by software reprogramming. Software can be downloaded into the modem through an auxiliary serial port which is part of rear panel connector 53. Extensive Built-In Test (BIT) functions are also included.

1.5 DATA TERMINAL EQUIPMENT (DTE) INTERFACE CRITERIA The modem is designed to interoperate with both MIL-STD-188-114 unbalanced interface and EIA standard RS-232D interface. The modem can be configured for synchronous or asynchronous operation. The following operation criteria should be considered when selecting Data Terminal Equipment (DTE) to interface with the modem.

1.5.1

Serial Tone Waveform Considerations

The modem requires the DTE to supply a Request to Send (RTS) to initiate transmission. If the DTE does not support RTS signaling, an external means of generating an RTS must be provided. The modem returns a Clear to Send (CTS) signal to the DTE when it is ready to receive data. Any data sent by the DTE prior to CTS being asserted is ignored. The DTE should drop the RTS signal between messages to ensure that a preamble is sent at the beginning of a new message. The Carrier Detect (CD) signal is active when the demodulator of the receiving modem is synchronized with the sending modem.

IS.2

Serial Tone Waveform Synchronous

Operation

Receive (RX) clock signals are generated by the modem. The source of the transmit clock signal can be set by the user: the modem can either provide the clock to the data terminal or accept it from the data terminal. CTS remains active until the RTS is dropped. The DTE rate must be the same as the transmission data rate.

1.5.3

Serial Tone Waveform Asynchronous

Operation

The modem and DTE use their own internal Transmit (TX) and RX data clocks. Sending and receiving DTE need not be set at the same bit rate; however, character length, parity, and number of stop bits must be identical between the DTE and the modem. Flow control can be set by the user to either the CTS signal or the XON/XOFF characters (if character length is 7 or 8 bits.) CTS is reissued when the modem is ready to accept more data from the sending DTE. The CTS signal is deactivated in response to the RTS signal being deactivated. The CTS and/or XON/XOFF flow control features will normally occur only if the DTE rate exceeds the over-the-air data rate. If the data terminal rate is less than the selected over-the-air rate, the modem automatically reduces the over-the-air rate to match the data terminal rate.

1.5.4

Frequency Shift Keying (FSK) General Considerations

An RTS signal from the DTE causes the modem to issue a keyline to the transmitter. Data rates of 75, 150,300, or 600 bps are allowed; when using an asynchronous DTE interface, 50 bps is also available. The modem returns a CTS signal to the DTE when it is ready to receive data. Any data sent by the D’TE prior to CTS being asserted will be ignored. The CD signal is active when the demodulator of the receiving modem is receiving a valid signal from the transmitting modem.

1.5.5

FSK Synchronous

Operation

RX clock signals will be generated by the modem, and TX clock signals can be programmed as either an input from the DTE or as an output from the transmitting modem. CTS will remain active until RTS is removed. Note that 50 bps is not allowed in this mode. 1-8

Flow control can be set by the user to either the CTS signal or the XON/XOFF characters (if character length is 7 or 8 bits.)

The CTS and/or XON/XOFF flow control features will normally occur only if the DTE rate exceeds the over-the-air data rate. If the data terminal rate is less than the selected over-the-air rate, the modem automatically reduces the over-the-air rate to match the data terminal rate. 1.6

REMOTE CONTROL

The modem can be controlled from any remote American Standard Code for Information Interchange (ASCII) terminal connected to the modem remote control port. Any modem operating parameters that can be manipulated from the front panel can be changed by the remote controller, except remote control interface parameters. The transmit keyline can also be initiated and terminated from the remote location. The modem is capable of reporting current operational and front panel status in response to polls from the remote control unit. The remote control interface is designed to EIA standard RS-232 and uses a simple ASCII interface. 1.7

FIRMWARE

UPGRADE CAPABILITY

Auxiliary serial port (part of 53) provides the ability to reprogram the modem. New firmware can be downloaded serially from a Personal Computer (PC) to the modem when future enhancements become available.

THE MODEM TO THE RADIO

Harris provides a 9-pin D matching connector to assist users in making a modem-to-radio cable. Refer to Paragraph 2.7.2. The modem has a standard 600 ohm transformer coupled audio interface with both open collector to ground and contact closure keyline circuits. Any radio used with the modem should match the following specifications: 0

600 ohm, +6 dBm to -20 dBm transmit audio

0

600 ohm, receiver output audio, fixed level, +5 dBm to -30 dBm

a

A keyline activated by open collector to ground or contact closure

0

A transmit and receive filter bandwidth of 300 Hz - 3000 Hz (2 3 dBm) NOTE Radios with specifications different than those listed may require a special radio interface cable. Most HF radios, however, have these listed features, thereby making direct connection to the modem possible. Radios with bandwidth less than that specified will cause degraded modem performance.

Use the 9-pin D connector provided with the modem to make the modem-to-radio interface cable. Refer to Paragraph 2.7.2. Figure 2-7 shows an example of a balanced audio configuration; Figure 2-8 shows an unbalanced configuration. Most radios accept a 0 dBm transmit signal (2.2 volts peak-to-peak into 600 ohms). If the system radio requires a lower transmit signal, refer to the Operation section of this manual to set the nominal transmit level between +6 dBm and -20 dBm (600 ohms) in 2 dBm increments. Some radios may require a delay between the assertion of the keyline signal and the start of the transmit audio from the modem. This delay may be required to allow a transmit circuit to power up or an antenna coupler to tune. Refer to Paragraph 2.13 for additional information. 2.10 CONNECTING

MODEM TO THE DTE

Harris provides a 25-pin D connector with the modem that matches with the 52 connector and is used to make a modem-to-DTE cable (refer to Paragraph 2.7.3). Figure 2-9 shows a typical modem-to-RS-232D DTE cable. 52 is the modem side of the cable. The other side shows the signal pinouts and descriptions as defined in the RS-232D specification. Some types of DTE require an indication that the modem is ready for operation. The RF-5710 provides a Data Set Ready (DSR) signal on pin 6 of 52. That signal is asserted true during the modem powerup initialization and remains true while the modem is powered on. If the DTE requires it, the signal should be connected as shown in Figure 2-9. Some types of MIL-STD-188-114A DTE require slower signal rise/fall times. The modem can be configured for slow rise/fall times by connecting pins 10, 11 on 52, the data interface connector. Alternatively, the position of JMPll on Jll can be changed inside the modem to position l-2. For standard rise/fall times, the internal jumper, JMPll, is to be in the 2-3 position and 52 pins 10,ll are not connected. The default factory setting is for standard rise/fall times.

In synchronous mode, the modem can either provide a transmit clock or accept an external transmit clock. 52 pin 15 provides a transmit clock signal output to external equipment when necessary, and 52 pin 24 is used for the input of an external transmit clock.

NOTE If the modem is programmed for External Transmit Clock, the DTE must provide the clock signal on pin 24 of the modem rear panel DATA connector 52. Failure to do this will result in a modem fault after the RTS is activated. Receive clock is always provided by the modem.

TX AUDIO DELAY

Some radios may require a delay between the assertion of the modem’s keyline signal and the start of TX Audio. The modem provides default minimum delay times that vary depending upon waveform and DTE mode of operation. See Figure 2-10 and refer to Tables 2-6,2-7, and 2-8. A programmable TX audio delay setting is provided to allow systems that require longer delays to extend the minimum timings. The delay can be extended from 0 - 39.9 seconds in 0.1 second increments from both the front panel and remote control. Changing this delay setting will affect when the transmit audio begins after the keyline signal is asserted. Adjusting this setting will also delay the assertion of the modem’s data port CTS signal in response to the DTE’s RTS signal (see Figure 2-10). This will require any connected DTE device to wait for CTS to be returned before transmitting any data to the modem’s data port through the RS-232 TX signal. If a DTE device and the modem are not set up to use RTS-CTS data port handshaking, any data sent before CTS responds will be ignored. Figure 2-10 demonstrates the RF-5710’s DTE data port handshaking signals in relation to the TX audio signal.

The following sections describe modem transmit and receive signal processing. See Figure 3-l for a functional block diagram of the modem.

3.2.1

Transmit Processing

Data from the data source is converted from MIL-STD-18%114A unbalanced levels to low level logic signals, then converted from serial to parallel form using a Dual Universal Synchronous/Asynchronous Receiver/Transmitter (DUSART). The Modem Control Processor (MCP) circuit performs initial data formatting depending on which waveform is selected (see Operations section for available waveforms). It then begins passing the formatted data to the Digital Signal Processor (DSP) circuit via a dual-port Random Access Memory (RAM). The DSP processors generate the selected waveform and modulate it with the transmit data. The digital information is sent to a digital to analog converter which converts it to an analog audio signal, which is then amplified and coupled to the HF radio transmitter via the transmit audio transformer. The MCP circuit activates the keylines to the transmitter.

3.2.2

Receive Processing

The signal output from the HF receiver is coupled in to the modem via the receive audio transformer, then routed to an analog to digital converter. The DSP processors then demodulate the signal to extract the data and pass it to the MCP processor via the dual-port RAM. The MCP performs final data formatting as required by the selected waveform. The parallel data is sent to the DUSART for conversion to low level serial form, then converted to MIL-STD-18%114A unbalanced levels and sent to the Data Terminal Equipment (DTE). 3-1

POWER SUPPLY

The power supply accepts input voltages in the range of 85 - 250 volts AC, with an input frequency of 50 or 60 Hz, with no internal strapping or voltage selection required. See Figure 4-2. The input power is routed from the rear panel AC input filter module to the front panel power switch, then to the power supply input connector. The power supply produces dc output voltages of +5V, -12V, and +12V, which are then routed to HF Modem Circuit Board Assembly A2. 3.4

FRONT PANEL ASSEMBLY

A5 Front Panel Assembly consists of an LCD display module and four pushbutton switches interconnected to A2 HF Modem Circuit Board Assembly by a flexible circuit. The LCD module displays two rows of 16 characters each. Key presses on the pushbuttons are detected by the modem control processor on A2 HF Modem Circuit Board Assembly, which processes the front panel inputs and sends menu and status information to the front panel display. 3.5

HF MODEM CIRCUIT BOARD ASSEMBLY

The following sections refer to the HF Modem Assembly schematic diagram. The first two sheets of the schematic contain a detailed block diagram of the circuits and list the sheet numbers for the corresponding circuit schematic diagrams. 3.5.1

MCP Circuit

The MCP circuit consists of 8OC186 microprocessor U6,256 kbytes of Read Only Memory (ROM) combined in integrated circuits U12, U13, U14, and U15,256 kbytes of RAM on UlO and Ull, and other associated support circuitry. Y2 is the master oscillator which has a frequency of 9.216 Mhz. The RAM power is backed up by battery BTl which ensures that the most recent set of user operating selections is stored in memory and are preserved when the modem is turned off or otherwise loses power. These settings therefore become the initial operating settings when the modem is subsequently turned on. The MCP circuit controls all modem interfaces, including the front panel display and pushbutton interface, remote control interface, and the data terminal interface. In addition, it performs initial processing of transmit data and final processing of receive data as required by the selected waveform. Data is passed between the MCP and DSP circuits via dual port RAM U46. 3.5.2

DSP Circuit

The DSP circuit consists of a Input/Output (I/O) Processor (IOP) circuit and a Coprocessor Circuit (COP). The IOP consists of TMS320C51 signal processor U30,256 k-words of ROM (U31, U32), 64 k-words of RAM (U36), and associated support circuitry. The IOP communicates with the COP via the dual-port RAM (U33). The COP consists of a DSP56156 signal processor (U27) and 64 k-words of RAM (U34). The DSP circuit performs all waveform generation, modulation, and demodulation functions. 3.5.3

HF Radio Interface

The IOP uses Analog Interface Chip (AK) U44 to convert the modulated transmit signal from digital to analog form. The signal is then amplified by U40 and U28, then routed to transmit audio transformer T2 and radio interface connector Jl. The transmit audio level is controlled by the MCP; the level selected by the user at the front panel is communicated to the IOP, which then adjusts the digital data values so that the level of the analog waveform matches the desired level. -

The audio output from the HF receiver is coupled to the modem via Jl and receive audio transformer Tl. It is buffered by U39, then routed to multiplying digital-to-analog converter U41. U41 is used by the IOP to implement Automatic Gain Control (AGC) of the received signal. The gain controlled output of U41 is buffered by U39, then converted from analog to digital form in AIC circuit U45. The outputs from U45 are used by the IOP for signal demodulation. 3-3

Data Terminal Interface

Transmit data, external transmit clock, and the Request to Send (RTS) signals from the data terminal are input to the modem through data terminal interface connector 52. Receiver U24 converts them from MIL-STD-188-114A levels to low-level logic signals. Channel A of DUSART U21 is used by the MCP to convert the serial transmit data to parallel form. Receive data from the modem is converted from parallel to serial from using channel B of DUSART U21. The receive data and control signals are converted from low-level logic to MIL-STD-188114A levels via drivers U2 and U3, then routed to DTE connector 52.

3.55

Remote Control Interface

Serial commands from the remote control terminal are input to the modem through Remote Control Interface (RCI) connector 53. Transceiver U25 converts the commands from RS-232 levels to low-level logic signals. Channel A of DUSART U20 is used by the MCP to convert the serial command stream to parallel form. Text to be displayed on the remote control terminal is generated by the MCP, then converted from parallel to serial form using channel A of DUSART U20. The serial data is converted from low-level logic signals to RS-232 levels in transceiver U25, then sent to the RCI connector 53. Channel B of DUSART U20 is an auxiliary serial port which provides external firmware upgrade capability. New firmware can be downloaded serially from a personal computer into the modem via RCI connector 53.

SECTION 4 MAINTENANCE INTRODUCTION

4.1

Advanced hardware and software design techniques have been used in the modem to minimize regular maintenance and simplify troubleshooting procedures. The Built-In Test Equipment (BITE) feature can be used to quickly identify faults and allow modem modular replacement in the field. The use of high-speed microprocessors, complex programming, and high integration surface mount components makes troubleshooting to the component level and repair difficult even when the proper test equipment is available. Therefore, we recommend that a spares program be developed through Harris Corporation. The modem is intended to be maintained by trained maintenance or service personnel. 4.1 .I

Protection of Static-Sensitive

Devices

Diode input protection is provided on all Complimentary-Metal-Oxide-Semiconductor (CMOS) devices. This protection is designed to guard against adverse electrical conditions such as electrostatic discharge. Although most static-sensitive devices contain some protective circuitry, several precautionary steps should be taken to avoid the application of potentially damaging voltages to the inputs of the device. Perform the following procedures to protect static sensitive devices from damage: a.

Keep all static-sensitive devices in their protective packaging until needed. This packaging is conductive and should provide adequate protection for the device. Storing or transporting static-sensitive devices in conventional plastic containers could be destructive to the device.

b.

Disconnect power prior to insertion or extraction of sensitive devices. This also applies to Printed Wiring Boards (PWBs) containing such devices.

C.

Double-check test equipment voltages and polarities prior to conducting any tests. Verify that no transients exist.

d.

Use only soldering irons and tools that are properly grounded. Ungrounded soldering tips or tools can destroy these devices. SOLDERING GUNS MUST NEVER BE USED.

e.

Avoid contact with the leads of the device. The component should always be handled very carefully by the ends or side opposite the leads.

f.

Avoid contact between PWB circuits or component leads and synthetic clothing.

4.2

BIT/BITE DESCRIPTION AND USE

Built-In Test (BIT) detects faults on the High Frequency (HF) Modem Circuit Board Assembly (10447-2000). If the modem does not power up, a systematic check of power connections, supply voltages, and fuses will identify the faulty module for replacement. Note that each module has specific instructions for removal and replacement.

4.3

FAULT ISOLATION GUIDELINES

The following paragraphs will help isolate and correct certain faults.

4.3.1

SECTION 5 OPERATION 5.1

INTRODUCTION

The Harris RF-5710-X95 HF Modem, shown in Figure l-l, has the ability to generate five High Frequency (HF) waveforms using the same hardware: MIL-STD-188-11OA Serial, Narrow Bandwidth Serial (SERIAL-NB), Frequency Shift Keying (FSK), the North Atlantic Treaty Organization Standard Agreement #4285 (NATO STANAG 4285), and the North Atlantic Treaty Organization Standard Agreement #4529 (NATO STANAG 4529). Each waveform is selectable from front panel controls and the current mode of operation is shown on the Liquid Crystal Display (LCD). The modem allows both half-duplex and full-duplex operation in most modes. A flexible, programmable interface ensures compatibility with a wide range of data and radio equipment. The single (serial) tone mode is based upon Phase Shift Keyed (PSK) modulation at a constant rate of 2400 bits per second. It is a full MIL-STD-188-11OA serial tone compatible mode. Known data segments are periodically inserted in the transmitted signal to allow for adaptive channel equalization at the receiver. Harris was the original inventor of the HF single tone demodulation technique and holds patent rights to the “Data Directed Equalization” technique. Convolutional coding (l/2 rate) and Viterbi decoding are combined with interleaving to provide unequalled performance in HF channels. Data rates of 75 to 2400 bits per second (bps), and 4800 bps (uncoded), are provided. Automatic data rate detection and automatic interleave setting detection are provided in receive mode. Lastly, a very robust adaptive Narrowband Interference (NBI) filtering algorithm allows data reception on channels with severe interference. The Serial-NB mode uses a non-standard waveform formatted similar to the MIL-STD-188-11OA waveform but uses a reduced bandwidth of 1240 Hz and provides comparable performance to the 3 kHz waveform. This allows it to be used where the existing frequency assignments cannot support the 3 kHz bandwidth required for the MIL-STD-188-11OA serial tone waveform. Serial-NB instead of a fixed 1800 Hz sub-carrier as in MIL-STD-188-llOA, provides independently selectable Receive (RX) and Transmit (TX) sub-carrier frequencies between 800 and 2400 Hz (in 50 Hz steps). The TX sub-carrier is modulated using up to 8 PSK at a rate of 1200 symbols per second. Data rates of 75 to 1200 bps, and 2400 bps (uncoded), are provided. Automatic data rate detection and interleaving setting detection is provided in receive mode. The NATO STANAG 4285 waveform uses a single 1800 Hz sub-carrier, which is modulated using up to 8 PSK at a rate of 2400 symbols per second. The difference from the MIL-STD-188-11OA is the way in which the data is formatted (refer to MIL-STD-188-11OA and STANAG 4285 for details). Data rates of 1200,240O uncoded, and 75 to 2400 coded, are provided. With the coded data, similar to the MIL-STD, known data is periodically inserted in the transmitted signal to allow for adaptive channel equalization at the receiver. Convolutional coding and Viterbi decoding, combined with interleaving, provide comparable performance to the MIL-STD. The NATO STANAG 4529 waveform is formatted similar to the NATO STANAG 4285 waveform, but uses a reduced bandwidth of 1240 Hz and provides comparable performance to the 3 kHz waveform. This allows it to be used where the existing frequency assignments cannot support the 3 kHz bandwidth required for the NATO STANAG 4285 waveform. NATO STANAG 4529 provides independently selected RX and TX sub-carrier frequencies between 800 and 2400 Hz (in 50 Hz steps). The TX sub-carrier is modulated using up to 8 PSK at a rate of 1200 symbols per second. Data rates of 600,120O uncoded, and 75 to 1200 coded are provided. The modem includes a Frequency Shift Keyed (FSK) mode of operation for compatibility with existing modems. User selection of mark/space frequencies over the range of 50 to 5995 Hz (5 Hz resolution) are accommodated. The binary FSK waveform is implemented with digital signal processing techniques.

FRONT PANEL CONTROLS

AND DISPLAY

This section describes all front panel controls and indicators, followed by descriptions of the FIELD, SCROLL, and ENTER buttons when operating the modem. 52.1

General Operating

Guidelines

Keep the following general principles in mind when operating the modem: The LCD display shows the current operating parameters of the modem. The FIELD button selects a parameter to be changed. The parameter keyword will begin to flash. Subsequently pushing the FIELD button will save the field parameter that is currently displayed and move to the next available field. Repeatedly pushing the FIELD button will result in returning to the initial field (wrap-around effect). A flashing field indicates two things: 1.

That parameter has been selected by the FIELD button.

2.

There are other choices available for that flashing field. The other choices can be displayed using the SCROLL buttons.

The SCROLL buttons step up or down through the choices available for that parameter. Repeatedly pushing either SCROLL button (scrolling in one direction only) will result in displaying all choices and returning to the initial choice (wrap-around effect). The ENTER button saves the field parameters that are currently displayed as the new operating parameters and causes the field to stop flashing. All parameter settings are saved at power down; the modem will power up with the same settings it had when it was turned off.

Modem Application

Failure Codes

The following error message may be seen on the front panel display if a failure is encountered while the modem is operating: LOSS OF EXTERNAL DTE CLOCK. This is the most common error occurring during synchronous operation of the modem. This failure indicates that the modem is expecting an external DTE clock signal and it is not being received or it is running at a rate that is different than the selected synchronous data rate.

NOTE This is not a modem failure; it is a system problem. If this failure occurs, verify that the DTE is providing a transmit clock at 52 pin 24, and that it is at the same frequency (rate) as the modem transmit data rate.

5.3.1.3

Modem Self-Test Failure Codes

One or more of the following error messages may be seen on the front panel display if a failure is encountered while the modem is performing a modem self-test (refer to the Maintenance section of this manual).

Mark and Space Frequencies

While operating the modem in FSK Variable Shift mode, the mark and space frequencies may be set to any value in the range of 50 Hz - 5995 Hz (in 5 Hz increments). Table 5-l shows the recommended minimum separation between mark and space frequencies and the maximum useable data rates which can be achieved with that separation.

NOTE When using the modem for HF radio communication purposes, the bandwidth of typical radio equipment limits the usable frequency range to 350 Hz - 3250 Hz. If it is necessary to adjust the mark and/or space frequencies, perform the following procedure. See Figures 5-12 and 5-13. a.

Push the FIELD button until the letter M in the Mark field (or S in the Space field) is flashing in the display.

b.

Push either SCROLL button. M (or S) will change to ? and the first digit (thousands place) of the frequency value to be changed will begin to flash.

Receive Frequency

5.9.5

Offset Adjustment

When operating the modem in FSK mode, it may be necessary to adjust the Receive Frequency Offset value in order to maximize the quality of the incoming signal and minimize the data bit error rate. The Receive Frequency Offset may be adjusted by increments of 10 Hz to a value 200 Hz above or 200 Hz below the center frequency that is currently selected, as shown on the front panel display of the modem. In FSK Variable Shift mode, the center frequency is internally calculated. The Receive Frequency Offset should be adjusted until a maximum tune meter value is achieved. The tune meter value is a relative value with 9 being the best possible value on the tune meter. The lowest possible tune meter value is 0, representing a very poor signal or no incoming signal at all. If it is necessary to adjust the Receive Frequency Offset value, perform the following procedure. See Figures 5-10 and 5-11. a.

Push the FIELD button until the Receive Frequency Offset display is flashing.

b.

Push either SCROLL button while observing the tune meter value for an increase or decrease.

C.

-

1.

If a decrease is observed, push the opposite SCROLL button until the tune meter value begins to increase.

2.

Continue pushing the SCROLL button until the tune meter value increases and begins to decrease.

3.

Push the opposite SCROLL button until a maximum tune meter value is displayed.

Push the ENTER button to lock in the displayed Receive Frequency Offset value and the parameters for FSK mode operation. The display will stop flashing. Special Considerations

5.9.6

FSK operation at 50 bps is limited to asynchronous DTE interface connections. In order to ensure that an unsupported combination of modem parameters (DTE interface, DTE data rate, and FSK channel rate) cannot be configured, parameter selection must be performed such that a valid configuration is always selected. The modem software prevents the selection of parameters which represent an invalid configuration and provides messages which indicate why the selected configuration is invalid. These messages appear on the front panel when the modem is under local control and on the remote terminal when the modem is under remote control. As a general rule, DTE data rate and FSK channel rate should be selected last when entering and first when leaving 50 bps FSK operation. 5.10 SETUP OPTIONS MENU This section describes how to access the Setup Options menu on the modem and select and change certain parameters. See Figure 5-14 while reading this section, and while using the Setup Options menu tree. Perform the following procedure to access the setup options menu:

SETUP Serial Duplex (Full, Half)

In Full Duplex operation, the modem can transmit and receive signals simultaneously. In Half Duplex operation, the modem can only transmit or receive at any one time. In Half Duplex operation, transmit has priority, which means that if the modem receives a Request to Send (RTS) from the data source while it is receiving a signal, it will interrupt the receive activity and begin sending. 5.10.1.2

Acquisition

on Data (OFF, ON, PKT)

The Acquisition on Data feature (Serial and Serial-NB modes only) allows the modem to acquire during a data message without requiring preamble detection. (The preamble is a synchronization sequence which the modem transmits at the start of a serial mode message.) This feature is useful in constant broadcast systems and in systems where the start of a message could be missed due to severe channel fading. In rare cases, the Acquisition on Data feature may interfere with the modem’s ability to acquire on an incoming preamble. Setting Acquisition on Data OFF will cause the modem to synchronize only on the preamble. This setting is recommended for most applications. When the modem’s Acquisition on Data option is set to PKT (Packet) mode, synchronization will only occur when a preamble has been detected and not on data. Selecting this mode may optimize the deacquisition process for using the modem to send short packets of data under certain channel conditions. If a channel presents severe fading, poor signal to noise ratio, or the time interval between successive data packets is small, this option may not provide a performance improvement.

510.6

SETUP Data Port

After selecting the data port submenu, the next choice is to set the data terminal interface for either synchronous (SYNC) or asynchronous (ASYNC) operation. To ensure proper data transfer, care must be taken that the modem data port parameters agree and are compatible with the DTE settings. 5.10.6.1

Synchronous

In synchronous mode, a data clock specifies the data bit transition rate. Several devices such as facsimile, cryptographic, and secure voice equipment require this type of operation. In this mode, the data rate of the DTE must match the transmit and receive over-the-air channel rates of the current operating waveform of the modem. Refer to Paragraphs 5.5 - 5.9 for waveform information. 5.10.6.1 .I

Polarity

(NORMAL,

INVERTED)

The modem provides the capability to invert the sense of transmit and receive data streams. This is rarely used for interoperability with some older types of DTE. Select INVERTED to reverse the sense of the data; otherwise, leave the modem in its default setting of NORMAL (which corresponds to RS-232D polarity). 5.10.6.1.2

Transmit

Clock Source (INT, EXT)

The modem can provide either a transmit clock to the DTE or accept one from the DTE (required by some cryptographic equipment). Set this parameter to internal (INT) for the modem to provide the clock. Set it to external (EXT) if the DTE is going to provide the transmit clock. NOTE If set to EXT, the data terminal must provide a clock to the modem. If a clock is not present when an RTS is issued, a fault will occur and the modem will display a fault message. The clock must be provided before the fault can be cleared. 5.10.6.2

Asynchronous

In asynchronous mode, the data bit transition rate is set at a fixed rate, and the data is grouped into characters defined by start and stop bits. The serial ports of personal computers typically use this type of protocol. It is critical that all asynchronous parameters be set to match the DTE for proper data transfer. 5.10.6.2.1

Polarity

(NORMAL,

INVERTED)

The modem provides the capability to invert sense of the transmit and receive data streams. This is rarely used for interoperability with some older types of DTE. Select INVERTED to reverse the sense of the data; otherwise leave the modem in its default setting of NORMAL (which corresponds to RS-232D polarity). 5.10.6.2.2

Rate (50,75, 150,300,600,

1200,2400,4800,9600

bps)

This parameter sets the transmit and receive DTE rates. The DTE rate can be higher than the current over-the-air waveform channel rates; if the DTE rate is higher, the modem uses flow control to stop and start the DTE data stream as needed to maintain the over-the-air channel rate. If the DTE rate is set less than the over-the-air waveform channel rate, the modem automatically adjusts the over-the-air channel transmit rate to match the data terminal interface setting. Note that 50 bps can be used only with FSK modes.

Stop Bits (1, 2)

This parameter sets the number of stop bits used to indicate the end of the data character.

5.10.6.2.4

Parity (Odd, Even, None)

Parity sets the type of character error checking recognized by the modem data port.

5.10.6.2.5

Character Length (5,6, 7, 8)

This parameter sets the total number of bits used to define each asynchronous data character.

5.10.6.2.6

Flow Control (CTS, XON/XOFF)

This parameter enables use of either a data control character (XON/XOFF) or the Clear to Send (CTS) signal to control the flow of data to and from the modem. When set to CTS, the modem uses the CTS signal at the data terminal interface to control flow. When set to XON/XOFF, the modem inserts special flow control characters into the data stream when it needs to regulate the flow. Most data terminals use CTS flow control.

5.10.7

SETUP Remote

The remote control interface is an asynchronous one similar to that described in Paragraph 5.10.6.2. The modem remote port parameters must match those of the remote control terminal for proper operation of the remote control feature.

5.10.7.1 Rate (1200,2400, 4800, 9600 bps) This parameter sets the transmit and receive remote control terminal interface rates.

5.10.7.2 Stop Bits (1,2) This parameter sets the number of stop bits used to indicate the end of the data character.

5.10.7.3 Parity (Odd, Even, None) Parity sets the type of character error checking recognized by the modem remote control port.

5.10.7.4 Character Length (7, 8) This parameter sets the total number of bits used to define each asynchronous remote control data character.

5.10.8

SETUP Display

5.10.8.1 Backlight (On, Off) This parameter turns the LCD backlight on or off. In most indoor applications, the backlight should be set to ON. In bright light conditions, setting the backlight to OFF may result in a better looking display. Changing this parameter immediately affects the backlight. Pushing ENTER is not required.

5.10.8.2 Contrast Level (0 - 9) The contrast setting affects the viewing angle and sharpness of the display characters. In most applications, the default setting of 5 should be adequate; however in temperature extremes or when installing the modem well beyond eye level, the contrast may need to be adjusted. Changing this parameter immediately affects the contrast. Pushing ENTER is not required.

5.10.9

SETUP Audio

5.10.9.1 TX Level The transmit audio level of the modem can be adjusted via this parameter. Note that the values are in dBm relative to a nominal 600 ohm load. If the actual load presented by the radio is something other than 600 ohms, the modem output will be slightly different than the front panel value. If accuracy is needed, an audio voltmeter should be used to measure the transmit audio while adjusting it from the front panel. Changing this parameter immediately affects the output level. Pushing ENTER is not required.

5.10.9.2 TX Delay This parameter is a system adjustment that should only be performed by a system expert. Adjusting this parameter sets an additional delay amount between the assertion of the modem’s keyline signal and the start of the modem’s TX audio. Refer to Section 2, Paragraph 2.13 for additional information.

-

The minimum added delay is 0 seconds and the maximum is 39.9 seconds, adjustable in 0.1 second increments. Pressing the FIELD button allows separate digits to be selected and adjusted using the SCROLL buttons. To make the selected delay amount take effect, press the ENTER button or use the FIELD button to go to the next selectable field.

5.10.10 SETUP Keyline The modem provides the ability to manually key and unkey the HF radio transmitter, as well as the ability to automatically key it based on the state of the DTE RTS signal. To key the transmitter, automatically set this parameter to RTS KEYS XMTR. In that mode, an RTS from the DTE will cause the modem to issue a keyline to the transmitter. When RTS is removed, the modem removes the keyline. Note that in some applications, the transmitter may require a long time from the assertion of keyline until it is ready to transmit. The modem will begin to transmit as early as 45 milliseconds (ms) after it receives RTS from the data terminal. If the HF transmitter is not ready to transmit within 45 ms, part of the transmission will be lost. Manual keying is recommended for those applications. To key the transmitter manually, set the parameter to KEYS XMTR; this must be done before sending data. The modem keyline output will immediately be asserted, although the modem will not begin transmission until it receives an RTS from the data terminal. Wait for the transmitter to become ready before sending data. To remove the keyline, set the parameter to UNKEY XMTR after data transmission has ended.

SECTION 6 REMOTE CONTROL 6.1

GENERAL

The modem has a remote control feature which allows the user to program all modem and data port parameters within the modem. Certain remote terminal equipment settings must be matched within the modem (e.g., character bits, stop bits, etc.). Once the interface is correct, the modem can be controlled through the remote port from an ASCII terminal or computer terminal. The modem has incorporated HELP and SHOW menus to assist the user. HELP lists all parameters that can be changed. SHOW lists the parameters and their values as they are currently programmed. The operator can program the remote control terminal to any number of di fferent settings (i.e., 9600 bps, 8, N 2) as long as the modem’s remote port is programmed identically.

If the remote control terminal is not functioning properly, it is usually a cable problem or a parameter setup mismatch. Certain parameter values have limited ranges, and some parameter values are fixed. If remote control commands attempt to change fixed parameters or exceed the acceptable range of limited parameters, the modem ignores the command, as shown below (operator input is in boldface type). RMT>modem type FSKWS RMT>modem rate 1200 Modem port sync Modem rate 600 RMT> The modem substitutes the closest available rate to the one requested by the modem rate command (600 is the highest rate that FSKWS can achieve). 6.2

REMOTE CONTROL EQUIPMENT

INTERFACE CRITERIA

Remote control commands are interfaced through REMOTE connector 53 on the modem. A text-like ASCII protocol is used for remote control syntax. Since the ASCII remote control protocol is generated by the modem, a simple ASCII terminal with an RS-232 interface will suffice as a remote terminal. Alternatively, several communication terminal emulation programs, such as PROCOMM TM,CROSSTALK’“, and RELAY GOLD TM can be used with a personal computer to interface with the modem, if desired. Refer to the Operation section of this manual for details regarding programming the modem. If the interface parameters have been changed for any reason, they must be reprogrammed to match the remote terminal’s requirements.

Commands shown boldfaced are commands that are entered by the operator using the remote control terminal. Responses from the modem are shown as normal text. The program parameters on the HELP menus (Figures 6-9 through 6-12) are listed with certain letters capitalized. These capital letters are the minimum number of characters that must be typed in for the command keyword to be recognized by the modem. For example, the show command can be executed at the remote terminal by typing the letters sh at the RMT> prompt and pressing the RETURN key (refer to Table 6-l). NOTE Remote control operation does not allow setting the bits per character parameter to 5 or 6 since this would no longer allow ASCII remote control.
