General
1.1 General Furuno’s “NavNet” is the Ethernet based high-speed network. NavNet products will allow us to customize marine electronics according to user’s needs with simple cablings. All display units are capable of controlling any component connected to the NavNet network. NavNet series include; 1) 2) 3) 4) 5) 6) 7) 8) 9)
7-inch monochrome radar/video plotter: Model 1722/1732/1742/1752/1762 7-inch color radar/video plotter: Model 1722C/1732C/1742C/1752C/1762C 10-inch monochrome CRT radar/video plotter: Model 1833/1933/1943 10.4-inch color LCD radar/video plotter: Model 1833C/1933C/1943C 7-inch monochrome STN LCD Video plotter: GD-1700 7-inch monochrome color TFT LCD Video plotter: GD-1700C 10.4-inch color TFT LCD video plotter: GD-1900C Network sounder: ETR-6/10N GPS receiver antenna: GP-310B
The GPS receiver antenna GP-310B looks like an antenna, but it is a compact 12-channel GPS receiver. The IF amplifier used on the NavNet series radars differs from model to model: Model 1722/1722C/1732/1732C/1742/1742C/1752/1752C/1762/1762C uses “Linear” IF amplifier, while Model 1833/ 833C/1933/933C/1943/1943C uses “Logarithmic” IF amplifier. An Ethernet repeating hub needs to be arranged locally for a multiple display system.

About The NavNet
1.2 About The NavNet The following describes more details about NavNet. The NavNet is a baseband network that provides a single channel for communications across the physical medium (e.g., cable), so only one device can transmit at a time. An analogy is a single phone lines such as you usually have to your house: Only one person can talk at a time – if more than one person wants to talk everyone has to take turns. Data travels in packets on a network. Packets are transmitted in standard Ethernet frames. The Ethernet header contains the destination and source addresses and the Ethernet type code. The data field immediately follows the header. +- - - - - - - -+ | 6 byte | | | +- - - - - - - -+ | 6 bytes | | | +- - - - - - - -+ | 2 bytes | | | +- - - - - - - -+ | ?? bytes | | | +- - - - - - - -+

The NavNet protocol is TCP/IP and the media access control mechanism used by the NavNet is CSMA/CD (Carrier Sense Multiple Access). Table 1 compares the NavNet with different physical types of Ethernet. Table 1.1

About The NavNet
All NavNet connections are point-to-point. This implies that a NavNet cable can have a maximum of two NavNet transceivers with one at each end of the cable. One end of the cable is typically attached to an Ethernet repeating hub or an active hub. The other end is attached directly to a NavNet product, which includes a NavNet network interface card (NIC). Two NavNet products may be directly attached to each other without a hub. In this case, a “crossover cable” (type: MJA6SPF0014), of which each end is terminated with a 6 position MJ connector, is used: one pair of wires is used for transmitting data, and the other pair for receiving data. When attaching a NavNet product to a repeating hub, a normal “straight through” cable is used and the cross over function is performed inside the repeating hub. In practically, when the NavNet is connected to the hub, a NavNet conversion cable (type: MJ-A6SRMD/TM11AP8-005) is required. The run length of NavNet cables is limited to 30 meters. The point-to-point cable connections of the NavNet result in a “star” topology for the network. A star topology consists of a central hub with point-to-point links that appear to radiate out from the center like light from a star. The star topology simplifies maintenance, allows for faster troubleshooting, and isolates cable problems to a single wiring link. (1) What is a hub? A hub is a common wiring point for star-topology networks. Hubs have multiple ports to attach the different cable runs. Hubs do not read any of the data passing through them and are not aware of a packet’s source or destination. Essentially, a hub simply receives incoming packets, possibly amplifies the electrical signal, and broadcasts these packets out to all devices on the network. Typically speaking, three different types of hub exist: 1) Passive 2) Active 3) Intelligent Passive hubs do not amplify the electrical signal of incoming packets before broadcasting them out to the network. Active hubs, on the other hand, will perform this function - - a function that is also present in a different type of dedicated network device called a “repeater.” Some people use the term “concentrator” when referring to a passive hub and the term “multiport repeater” when referring to an active hub. The NavNet uses an active hub. Intelligent hubs add extra features to an active hub that are of particular importance to businesses.

(3) What happens when a collision occurs? A collision occurs when two devices transmit at exactly the same time. Since only one device can transmit at a time, both devices back off and attempt to retransmit again. Each device waits a random amount of time and the two are very likely to retry at different times. Thus the second one will sense that the network is busy and wait until the packet is finished. If the two devices retry at the same time, they will collide again, and the process repeats until either the packet finally makes it onto the network without collisions.

Network setup
1.6 Network setup The NavNet uses TCP/IP data communication protocol. TCP/IP is a set of protocols which allow cooperating computers to share resources across a network. TCP stands for Transmission Control Protocol (TCP) and IP for Internet Protocol. IP provides the basic packet delivery service for the NavNet. The IP protocol implements a system of logical host addresses called IP addresses. The IP addresses are used by the NavNet to identify devices and to perform internetwork routing. IP is a connectionless protocol, which means that IP does not exchange control information (called a handshake) to establish an end-to-end connection before transmitting data. The IP addresses are assigned to the NavNet display units before shipment as below. It is necessary to change the last three digits of the IP address when like models are used in a network. Never set the same IP address in the network. The three digits is any number between 001 and 254.

Network setup
In addition to the entry of the IP address, Host name, Radar source, Chart source, and Sounder source must be entered to get various display modes and display combinations in the NETWORK SETUP menu. 1) Host Name: Type a name for own display unit to distinguish it from others in the network. The factory-default is shown in the above table. The name can contain figures. 2) Radar Source: Type the host name of the display unit from which the radar picture is received. This line is factory-set to RADAR for Model series display unit which comes with the scanner unit. 3) Chart Source: Type the host name of the display unit from which the chart data is received or which has chart card in its slot to use. A maximum of three units, excluding own display unit are preset on three lines. 4) Sounder Source: Factory-default is SOUNDER to connect the network sounder ETR-6/10N to the network. When the ETR-6/10N is not connected, blank this line so that the sounder symbol in the display selection window is disabled with a red X mark. Subnet mask, Gateway address, and Offset port number are not used. Never change these values. (SUBNET MASK: 255.255.000.000; GATEWAY ADDRESS: 000.000.000.000; and OFFSET PORT NUMBER: 10000) Radar source and sounder source are also selectable through the user accessible Select source menu. When two radars or more are connected in the network, either of them is selected through the Select source menu by the user. Note that at the moment, one netsounder can be used in the network. The Sounder option is for future-use.
Important! The same radar source should be selected on the NavNet plotter display units. Never select different radar source on each plotter display unit if two radars and plotters are in the network. For example, in the network shown in the figure below, radar source must be selected to either M1943C or M1833C on both plotters. Table 1.6 shows the example of setup menu setting for a network shown in Figure 1.10.

The radar picture includes Heading data so that the display in HU, NU, or CU mode is available on the plotter. TTM data is switched on and off through OUTPUT THROUGH NETWORK menu. A target is acquired and tracking target is erased from the plotter. Note that only one radar in the network can be quipped with ARP board. Table below summarizes controls of radar picture and ARP targets. Table 1.8

Circuit Description
This chapter describes the circuit of NavNet series products briefly.
2.1 General NavNet series radar is divided into two groups depending on the type of IF amplifier. One uses a linear IF amplifier and the other a logarithmic amplifier. Figures 2.1 and 2.2 show the simplified block diagram of each system. TX: The trigger pulse, generated on the Processor (SPU) board in the display unit, is delivered to the modulator in the scanner unit to oscillate the magnetron. The radar emits radio wave from the radiator with the magnetron oscillating. RX: The 9.4 GHz echo signal received by the antenna is converted down to 60 MHz IF signal by the MIC. The IF amplifier amplifies the IF signal and output it to the video circuit on the SPU board. The signal is displayed on the screen after digital signal processing. The received signal is gain-, A/C sea-, and A/C rain-controlled in the linear IF amplifier, while the signal is not controlled in the logarithmic amplifier but it is controlled in the video amplifier on the SPU board in the display unit. Auto plotter (Optional): Applied from the SPU board to the ARP board are; 1) Heading in AD format 2) 8192 bearing pulse 3) Video 4) Trigger 5) Ship’s speed in IEC-61162 format. The ARP board acquires and tracks targets. Data and symbol of the acquired target are displayed on the screen via the SPU board. Target data includes position, CPU, TCPA, speed, and course.

2.3.1 Auto Tuning Function At not only installation but also the replacement of RF unit, magnetron, MIC, and SPU board, “tune initialization” must be carried out through the tuning setup menu. The receiver is tuned automatically for maximum echoes and tuning control voltages found are stored onto the EEPROM on the SPU board. Tune initialization is carried out in two steps. First, full search is performed using a long pulse to find a coarse tuning voltage (a). Then, short search is performed for all pulses. After initialization, the pulselength which was used before is selected. In full search, tune control voltage (TUNE CONT) varies from about 1 V to 10 V and one that produces the maximum tune indicator voltage or coarse tuning voltage is memorized onto the EEPROM.

Figure 2.7 Tuning initialization process In short search, tune control voltage changes from coarse tuning voltage plus 2.5 V to coarse tuning voltage minus 2.5 V. This search is made with long, middle, and short pulses to find the fine tuning voltage. At daily use, the short search is made twice when the radar is set from ST-BY to TX and once when the plulselength is changed in auto tuning mode.

2.3.2 Manual tuning When tune mode is changed from auto to manual, the coarse tuning voltage is selected. In manual tune mode, tuning voltage is indicated graphically under the tuning indicator. The minimum scale is 3 V and the maximum scale is 10 V.
2.3.3 Tuning Indication The tuning indicator is adjusted so that the tuning indicator extends more than 80% of its full length on all ranges at best tuning. The extension on short pulse is shorter than long pulse and the indication becomes shorter when the magnetron degrades.
2.3.4 Video Level Adjustment (03P9288/19P1001) The video input level to the linear video amplifier must be adjusted through the installation menu at not only installation but also the replacement of RF unit, magnetron, MIC, and SPU board. The following describes the outline of the adjustment mechanism on the SPU board, 19P1001. The SPU board, 03P9288 has the same circuit as 19P1001, but it has different parts numbers. The following describes the outline of the adjustment. (These are carried out automatically.) 1. Main Bang suppression Level (MBS L) is set to 0. 2. EEPOT, U14 is set to minimum. (EEPOT initialization with "L" level of U14 #7) 3. EEPOT gets into step-up mode (U14 #2 is H.) to measure output video level at each step. The step is changed by pulses applied to U14 #1. The step where the output level is 2.2 V is memorized. 4. EEPOT gets into step-down mode (U14 #2 is L) to find and stores the step number where the output level is 2.2 V. 5. Averaging the step numbers found in steps 3 and 4 above, and saving onto depot. The stored value is not erased when power is turned off. 6. MBS L is reset to the value previously used.

2.3.5 Echo Averaging (EAV) Echo averaging circuit is designed for; 1) Discriminating small and weak targets such as flocks of birds, small ships, and fishing floats hidden in sea clutter, and 2) Displaying long-range targets stably. Normally echoes from sea clutter and noises do not appear on the screen at the same position in successive scans. The circuit can provide the different echo levels, correlating echo data at each scan so that the level (intensity) of the echo which appears at random position decreases. For example, echoes from target and sea clutter are displayed on the screen in the same level with EAV off. But the echo from sea clutter is displayed in lower level than target echo with EAV LOW. The return from the sea clutter appears at the different position at every scans and EAV LOW sets the echo level to low at first and second hits. The target echo appears more than three successive scans at the same position, so it gets the maximum echo level. The EAV MED gives the maximum level to the target which has four consecutive hits or more. The EAV HIGH prolongs the afterglow time of echoes. Echo averaging is a useful function when it is used properly. However, target may be lost if this function is used with improper settings. The echo averaging requires heading and LL data. Echo level

ARP Function (optional)
2.4 ARP Function (optional) 10-inch CRT and 10.4-inch LCD radars, Model 1833/1833C/1933/1933C/1943/1943C, provide ARP function if they are equipped with an optional ARP-11. The ARP board cannot be mounted on the 7-inch radars. The ARP-11 has the same circuitry and software as ARP-10, but the board is small in size. The ARP-11 requires heading data in AD format and speed data in NMEA format. Heading data in NMEA format and contact-closure speed log signal are not acceptable. The ARP-11 acquires and tracks 10 targets manually and automatically. The ARP display can be turned on/off through the ARPA TARGET INFO/ARPA Setup menu which has the following options. 1) Internal ARPA: Is selected when the radar is equipped with the ARP board and when TTM data is received via NETWORK port. Target can be acquired and cancelled from any display unit in the NavNet network. 2) External ARPA: Is selected when the display unit receives TTM data via NMEA port. Target tracks are shown but targets cannot be acquired. 3) Off Figure 2.10 shows the simplified block diagram of the ARP board, 18P9013.

ARP Function (optional)
Unlike other existing ARPs, ARP-11 does not require QV level adjustment at installation and no test point for QV echo is provided. The system checks the connection of the ARP board at every power-on. If the CPU on the SPU board fails to communicate with the ARP CPU, the message “ARP is not connected.” appears and the ARP line is not displayed in the selftest display. The ARP board generates the track of the tracking target. In the “radar” display mode, the past position is displayed by equally time-spaced dots and in the “plotter” mode, it is displayed by a solid line. To display the track in the plotter mode, the board memories the position of the tracking target at the same interval as own ship’s plot interval. A maximum of 10 positions is memorized for each target and these points are connected. Table 2.1 Display mode

When the target is not acquired, carry out the self-test at TX condition. TRIGGER, VIDEO, BP, HD must be OK, and FE-DATA 1 and FE-DATA 2 must vary depending on the gain setting. The lower the gain setting, the smaller the FE DATA value. The FE DATA must not exceed 1000 with the maximum gain setting. The APR works in the following conditions. Land echo discrimination A target measuring about 800 m or more in the radial or circumferential direction is regarded as a landmass and not acquired or tracked. Echoes smaller than about 800 m are regarded as true target. Manual acquisition 1) Within 9 scans, the target must be detected near the cursor position. 2) Target echo must be smaller than land echo (800 m or less in the radial or circumferential direction) at the front-end processor. 3) Target must be within acquisition area: 0.1 to 16 nm. 4) The number of acquired targets is not as many as 10, including the target manually acquired. 5) No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected. Automatic acquisition 1) The target must be detected for five consecutive scans within the automatic acquisition area. 2) Target echo must be smaller than land echo (800 m or more in the radial or circumferential direction) at the front end processor. 3) Target must be within acquisition area: 2.0 to 2.5 nm and 45° each side of heading line. 4) The number of acquired targets is not as many as 10, including the target automatically acquired. 5) No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected.

2.4
ARP Function (optional)
Automatic acquisition 1) A tracking target is judged as a lost target when no return is received for nine consecutive sweeps. When the system detects a loss of a tracking target, the target symbol becomes a flashing diamond. 2) A lost target will be reacquired and tracked when acquisition condition again becomes satisfactory. 3) Automatic tracking is discontinued when the target moves out of the acquisition range (less than 0.1 nm or greater than 16 nm).

2.5 PWR Board PWR boards, 03P9282, 03P9283, 03P9296, and 19P1005, are similar in circuitry, but the parts numbers are different. The power supply circuit, except for 03P9282, consists of a primary circuit and a secondary circuit. The primary circuit uses a switching regulator and generates –12 V and +12 V. The secondary circuit is powered from +12 V generated by the primary circuit. Table 2.2

On SPU (03P9286) board, -15 V is generated from -24 V by Q13 and CR4 for 7-inch color LCD display. The following describes how PWR board works in the example of 19P1005. See Figure 2.11, the block diagram of the power supply circuit, 19P1005. This board consists of main-inverter, sub-inverter, and brilliance control circuit. The main-inverter produces –12 V and +12 V, and the sub-inverter produces +3.3 V and +5 V. On the SPU board, +2.5 V is generated from +5 V with a regulator Q35. The power failure signal P FAIL N is generated by U7 and Q17 before the power supply circuit is shut down.

Protector Circuit (19P1005) The power supply circuit is protected against input low-/over-voltage and short circuit of line voltage. Provided are following power failure detectors. 1) Input over-/low-voltage detector The detector U3 outputs Low signal when ship’s main is not within the rated input voltage range. CR4 conducts and Q5 turns on. Thus, the switching oscillator U2 stops oscillating with its pin #5 (DT) High. If ship’s main is not within the range for 5 seconds, 5 sec delay circuit, consisting of Q9, Q11, R28, CR7, and C19, activates with CR5 on. Q12 is on and a reset signal is applied to the flip-flop U4. Q14 and Q13 are off. (C19 is discharged through R28, CR6, and R31.) If ship’s main becomes within the range within 5 seconds, the oscillator U2 starts oscillating again. 2) +/-12 V line short-circuit detector When +12 V or –12 V line short-circuits, overcurrent flows in the primary winding circuit of the main-inverter. The overcurrent detector, consisting of U1, R1, R2, and R3, detects this current. The output of U1 becomes low and Q3 is on. Thyristor Q6 is triggered. Q5 is on and the oscillator U2 stop oscillating with its DT pin High. With Q6 on, 0.5 sec delay circuit activates and Q13 is turned off to switch off 10 V supply. 3) +5 V line short-circuit detector When + 5 V line is short-circuited, U9 stop oscillating. Note that the main-inverter is still alive. 4) +3.3 V short-circuit detector When +3.3 V is short-circuited, overcurrent flows through R87 and R88, causing that Q27 is on. When Q27 conducts, Q19 is on and SCP line becomes Low. A photocoupler U5 triggers 0.5 sec delay circuit and the flip-flop U4 is reset. Q13 is off finally. U9 stop oscillating immediately after the short circuit of +3.3 V line with #3 pin of U9 low. 5) +2.5 V short-circuit detector On the SPU board, a photocouper detects the short circuit of +2.5 V line. The PWR OFF line becomes High and Q6 is triggered. 6) When the CPU freezes, PWR OFF signal is not generated. In this case, hold down the PWR switch for 5 seconds. Q8 and Q9 are on. C19 is discharged through R28, CR6, and R31. CR7 conducts when C19 is discharged to about 3.6 V. Then, Q12 is on.

NTSC/PAL I/F Board (19P1004, optional)
2.6 NTSC/PAL I/F Board (19P1004, optional) On the board, NTSC and PAL signals, having ITU-R601 compliancy, are converted from analog composite video signal into RGB signal for representation of video information on VGA LCD display. The board features automatic NTSC/PAL recognition so that input video signal is selected automatically to either NTSC or PAL mode depending on the number of lines per field. The analog video signal is converted into digital data through the AD converter inside the composite signal digital video decoder, and sampled by the clock at the pixel frequency from the SPU board. This board is sometimes called Picture-In-Picture (PIP) board. Figure 2.16 shows the block diagram of the NTSC/PAL I/F board. The heart of the circuit is a NTSC/PAL digital video decoder, MSM7662 or MSM7664. DRAM 1

MD-9208 The modulator produces high voltage pulses to drive the magnetron. The modulator board consists of pulse width selector, modulator trigger circuit, FET driver, and booster pulse transformer. See Figures 2.18 and 2.21 for the block diagram of MD-9208. The modulator trigger circuit, U811 (U808) and associated parts, generates a pulse to turn on FETs Q815 and Q816. The pulse is generated when TX TRIG pulse is received from the display unit. The pulse width is determined according to the P/L A and P/L B signals from the display unit. Other modulator boards work in the same principle. 03P9270 This board provides two switching regulators: one generates –6V, +5V and +12 V, and the other 8V (magnetron heater voltage) and TX high tension. VR851/VR852 (VR851) adjusts the output power of the magnetron. Part number in parentheses is for old board.

03P9235/A–33 (MODEL 1762/1762C/1933/1933C/1943/1943C) This board contains the power supply circuit which generates TX HV, +28 V, and 7.6V (magnetron heater voltage). The difference between 03P9235 and 03P9235A is listed in table 2.4. The main function of the modulator section is to produce high voltage pulses to drive the magnetron. To produce these pulses, the MODULATOR Board has a modulator trigger circuit, modulator pulse generator and booster pulse transformer. The modulator trigger circuit consists of U808 and associated components. This circuit generates the pulses which cause modulation FETs Q805, Q806 to conduct. The pulses are produced when the TX TRIG pulses from the display unit is received and U808 conducts. The voltage of the pulses is raised at pulse transformer T802 until it is 3.5 kV (4.5 kV for 6 kW). This circuit adjusts the electrical current flowing into the magnetron so it is 3 A (3.5 A for 6 kW). The MODULATOR Board also contains the TX high voltage circuit and the magnetron heater circuit. The TX high voltage circuit charges capacitors with 300 V (330 V for 6 kW) high voltage produced at the primary windings of T801 and discharges them once the TX TRIG pulse is received. The magnetron heater circuit produces stable +7.6 V. Table 2.4

03P9235/A–22 (MODEL 1762/1762C/1933/1933C/1943/1943C) This board contains the power supply circuit which generates TX HV, +20 V, and 7.6V (magnetron heater voltage). The difference between 03P9235 and 03P9235A is listed in table 2.5. The main function of the modulator section is to produce high voltage pulses to drive the magnetron. To produce these pulses, the MODULATOR Board has a modulator trigger circuit, modulator pulse generator and booster pulse transformer. The modulator trigger circuit consists of U805 and associated components. This circuit generates the pulses which cause modulation FETs Q805, Q806 to conduct.

2.8.2 IF amplifier board The IF amplifier board consists of IF amplifier and tuning indicator circuit. There are two types of IF amplifier used in the NavNet series: linear and logarithmic. Linear amplifier: 03P9269, IF-7758C, and IF-9215 Logarithmic amplifier: IF-9214 03P9269 Two types of 03P9269 exist : original type (–44) and current type (–66). The change was made at the beginning of 2002 to improve S/N ratio. –44 IF AMP board cannot be used with mew MIC, S-RX50A, became of different connector type. New IF AMP board fits two connectors for new and old MICs. The IF amplifier, the intermediate frequency of 60 MHz and band width of 7 MHz, consists of Q1, U1, U2, and a buffer Q4. This board includes the gain and STC control circuits consisting of Q3 and Q5 (Q2 and Q3). Another circuit, consisting of Q10 to U6 (Q5 to Q10), detects the main bangs to indicate the tuning level. Part number in parentheses is for old board. STC Control GAIN Control Trigger

IF-9214 The IF amplifier receives 60 MHz signal from the MIC through the bandpass filter, of which bandwidth is 25 MHz for 0.08us and 0.3us TX pulses and 3 MHz for 0.8 us. U1, U2, U3 are a logarithmic amplifier. The mixer Q1 and Q2 is provided to ensure wide dynamic range of the received signal. This board includes a Tuning Indicator circuit. 60 MHz IF signal from the MIC is amplified by the logarithmic amplifier U4 and sampled with the main bang signal. The signal is further amplified and detected by Q10 and Q11. Then send to the display unit as TUNING IND signal through the buffer circuit, Q13 and Q14. IF-7758C and 03P9310 See block diagrams on the next page.

2.8.3 MIC MIC circuit converts microwave signal into 60 MHz intermediate frequency signal. Figures which follow show the block diagram of the typical MIC. The RU-9360 does not have a RF amplifier but the IF amplifier. The diode limiter, set after the converter, protects the balanced mixer from the excessive input power, and the mixer converts the input microwave signal to the IF signal. A voltage-controlled FET oscillator outputs the signal to the mixer. Type

Adjustment
Hazardous Voltage This equipment uses high voltage electricity which can SHOCK, BURN or cause DEATH. Always make sure the electrical power is turned off before attempting to change a component or inspecting the inside of the equipment. A residual charge may exist in capacitors, even with the equipment turned off. Always short all supply lines to the chassis with an insulated screwdriver or a similar tool before touching the circuit.
Working on the Scanner Unit Mast Work on the scanner unit mast is dangerous, and doubly so if the proper precautions are not taken. 1. Post an appropriate warning sign near the display unit to indicate that work on the scanner unit is being performed, to prevent accidental application of the power to the scanner unit. 2. Wear a safety helmet and always be aware of where the scanner radiator is.

5.4 Replacement of Major Parts
5.4 Replacement of Major Parts Remarks on Replacement of Major Parts 1) Turn off the power before replacing any parts. 2) Do not touch the magnetron while the radar is transmitting. Sufficient high voltage exists at the magnetron to cause death. MAGNETRON The magnetron generates a strong magnetic field. For this reason, remove wristwatch before performing the replacement and use a non-magnetic screwdriver to dismount and fit the magnetron. The estimated life of the magnetron is 2000 hours, (including time in stand-by), however actual life depends on usage. 1. Turn off the power. 2. Dismount the transceiver module. 3. Replace the magnetron with new one. 4. Turn on the unit and wait for at least 30 minute for magnetron pre-heating under ST-BY. 5. Measure magnetron heater voltage and adjust it if necessary. See Chapter 4 for the rating. 6. Set the radar to TX on long range and measure magnetron current. See Chapter 4 for the rating. 7. Reset "TOTAL ON TIME" and "TOTAL TX TIME" on page 2, RADAR SETUP menu. See 1.9 Special keystrokes in Chapter 1 for the procedure how to access Installation menu. MIC The MIC can be replaced individually. No adjustment is necessary after replacement.
SPU Board Save data, menu and installation settings, on to the memory card before replacing the board. Then, after removing the board, play back it from the memory card. (Reason: Settings are stored on EEPROM and SRAM located on the SPU board.)
IMPORTANT! After replacing the SPU board, factory menu setting must be carried out properly.

1.4 Power supply circuit The power supply circuit is divided into two blocks: Stand-by 3.3 V circuit and main power supply circuit which generates +12 V, +/-5 V, and +100 V. When power, 10.8 to 31.2 VDC is applied to the circuit, stand-by 3.3 V circuit is turned on and the network sounder is in stand-by mode. When the NavNet display is turned on, the network sounder CPU generates the signal to release the stand-by mode and to turn on the main power supply circuit. The on/off switch of main power supply circuit consists of Q16 and photocoupler U29. The STBY N signal becomes High, current flows through U29. Switching frequencies of stand-by 3.3 V circuit and main power supply circuit are 65.5 kHz (adjusted at TP6 with R137) and 83.7 kHz (adjusted with R133 at TP5) respectively. R119 adjusts +100V. The protectors provided are; 1) Input low-/over-voltage protector, U32 2) Reversed polarity protector, CR26 3) Input over-voltage protector, 4A fuse, F1 4) Short circuit protectors for each output line 3.3 V: polymer switch, RT2; regulators U21 (-5V), U22 (+5V), and U25 (+12V) include a short circuit protector.

Transducer Check
7. Transducer Check This section describes the procedure to check the transducer.
7.1 Measuring capacitance A barium titanate transducer functions based upon the principle of electrostriction, so it is equivalent to a capacitor electrically. By measuring the capacitance of the transducer with a capacitance meter, the transducer can be judged whether it is good or not. The transducer name consists of working frequency and type. In the example of 50B-6, the 50 stands for working frequency: 50 kHz and B for Barium titanate transducer. Following table shows the capacitance of transducers. These values are reference only and include the capacitance of 10-m cable (100 pF/m). Table A.6 Transducer Type 50B-6 50B-6G 50B-12 200B-5 200B-5S

Figure A.7 Circuit for measuring impedance To measure the impedance; 1. Set the SW to #1. 2. Set the output frequency of a signal generator to the resonant frequency of the transducer. 3. Measure the voltage across the transducer with an oscilloscope. 4. Set the SW to #2 and adjust the potentiometer so as to obtain the voltage measured at step 3. 5. Measure the resistance of the potentiometer. This resistance is the impedance of the transducer at the resonant frequency. Note that the impedance of the transducer differs under the different measuring condition, i.e., in air or in water. The table A.7 shows the impedance (Ro) and resonant impedance (Z) of the transducer in water.

Resonant curve
To check the transducer whether it is good or not, compare the curve with one obtained from a good transducer. 1) When transducer elements peel off the housing, the ratio of A to B increases. This is similar to he measurement in air. 2) When transducer element cracks, several other resonant points may be obtained. 3) When transducer element splits, resonant point may be not obtained at the frequency "Fo".

Since the waveform differs with the resister "R" and the measuring condition (i.e., in water or in air), the resister and measuring condition must be the same when checking the transducer.

Radar Simulation Data
How to change “Radar Simulation” data Navnet has two radar simulation or demo modes: Simulation 1 and Simulation 2. The simulation 1 shows the same radar picture as that of the echo generator EG-3000. The simulation 2 shows the picture of our Miki factory. Both are still pictures. These pictures can be changed by using the following procedure. At an exhibition, showing the radar picture of the site for the exhibition gives more impression to the attendance. Overwrite 1) Configuration A heading sensor is required if the data is reproduced in overlay mode. The radar picture cannot be overwritten by the data received in the network. GP-310B

Power Supply Unit PSU-005
The power supply unit PSU-005 includes p.c. board 19P1006 consisting of +/-12V switching regulator, +32 V regulator, Tuning Control Circuit, and 90-second timer. The unit receives PWR ON signal from the display unit. The +/-12V switching regulator is similar to that on 19P1005. U2 is a PWM switching regulator controller. At power-on, +10V is supplied to switching regulator controller U2 through Q4. The switching frequency is set to 45 kHz by R20. R23 adjusts +12 V line to 12.2 V. CR10 lights when +12 V line is normal. To generate stable voltage, U2 receives a feedback signal at #2 (ININV). +32 V regulator, consisting of U6 and associated parts, generates +32 V from 12 V. +32 V is used in the tune control circuit. U7 is the tune control circuit. Tune control voltage is sent from the display unit to J5 on 19P1006. The input voltage, ranging from 1 V to 11V, is boosted up to between 1 V and 31 V. The output is connected to the MIC in the scanner unit via #6 of DJ1. CR13, TP5, and S1 are provided for adjusting the tune control circuit at installation. Set the slide switch S1 to the upper position (short circuit between #2 and #3). Transmit the radar on a long range with the antenna stopped. Adjust R36 clockwise so that CR13 lights in the maximum brightness, or, the maximum voltage is measured at TP5. After the adjustment, set S1 to the lower position (short circuit between #1 and #2). 90-second timer, consisting of U10, U11 and associated parts, locates in TX TRIG line. This circuit prevents the transmitter from being damaged by triggering before preheating of the transmitter, or within about 90 seconds after power on. R61 is used to adjust the timer so that TP7 is 100 kHz.
C-2
2. Power Supply Unit PSU-005
Protector 1) +/-12 V line short-circuit When +12 V or –12 V line short circuits, over-current flows in the primary windings of output transformer T1. The over-current detector, consisting of U1, R1, R2, and R3, activates. That is, U1 outputs low signal and Q6 turns on. Q7 is triggered into conduction. Q8 is on. Thus, DT terminal of U2 becomes high and U2 stops oscillating. 2) Antenna motor power supply line U9 turns on when the motor power supply line short circuits. C37 is charged through CR15 up to about 2.5V and U8 turns on. When U8 is on state, Q6 turns on. Q7 is triggered into conduction. Q8 is on. Thus, DT terminal of U2 becomes high. C37 discharges through Q10.
