Jotron B120 Stabilized VSAT Ku-antenna
Service Guide
CAUTION: This stabilized antenna system is designed with a transmitter (Transceiver or BUC). A transmitter involves potential hazards, including exposure to RF radiation, associated with the improper use of the transmitter. The transmitter could operate independently of the stabilized antenna system. Prior to work on the stabilized antenna system, the power to the transmitter must be switched off. When the transmitter is in operation, no one should be allowed anywhere within the radiated beam being emitted from the antenna. The ultimate responsibility for safety rests with the facility operator and the individuals who work on the system. Potentially lethal voltages are present within the ADE (Above Deck Equipment) and the BDE (Below Deck Equipment) .To avoid electric shock, do not open the chassis enclosures of the BDE unless you are a Jotron certified technician. Access inside the radome is only allowed for a Jotron certified technician.
Inside the radome of the ADE (Above Deck Equipment) a moving pedestal is present. While opening the hatch, entering the radome or doing service on the pedestal please be observant so you are not hit by the moving pedestal. The hatch shall always be securely locked unless a Jotron certified technician is doing service inside the radome.

2.1 Using this manual These instructions explain how to service the Jotron B120 VSAT stabilised antenna. Instructions on how to use the system are provided in the User’s Guide and Installation Guide describes how to install the Jotron B120.
2.2 Important safety information For your own safety, and for the safety of your passengers and/or crew, be sure to read the following important notices.
2.2.1 Warning - Risk of Electric Shock Potentially lethal voltages are present within the ADE (Above Deck Equipment) and the BDE (Below Deck Equipment) .To avoid electric shock, do not open the chassis enclosures of the BDE unless you are a Jotron certified technician. Access inside the radome is only allowed for a Jotron certified technician.
2.2.2 Warning- Risk for moving platform inside radome Inside the radome of the ADE (Above Deck Equipment) a moving pedestal is present. While opening the hatch, entering the radome or doing service on the pedestal please be observant so you are not hit by the moving pedestal. The hatch shall always be securely locked unless a Jotron certified technician is doing service inside the radome. Radiation Hazard
2.2.3 Caution - RF Radiation Hazard The antenna transmits radio frequency (RF) energy that is potentially harmful. Whenever the system is powered on, make sure everyone stays more than 20 feet (6 m) away from the antenna within its 5°90° elevation range. No hazard exists directly below the antenna’s mounting plane. If a person is standing outside the antenna’s main transmission Beam, minimum safe distance is 1 foot (0.3 m). However, since person may not know which direction the antenna is pointing, it is always best to observe the full 20 feet (6 m) minimum safe distance. Passenger safe distance 16 meter

Revision A 2012-08-06
Indicates Indicates: - Automatic Calibration of sensors, “test 1” - If needed it will start after sensor Unit has moved to end stop and back to position of 0 degree elevation. - Failure on motor - Motor driver failure (ASU) - Power supply, not giving enough power to drive the antenna. - Mechanical obstruction or friction causing system to shout off power to the motor Automatic Calibration may be initiated after sensor Unit end-stop calibration and/or after antenna has detected the home sensor. (Automatic calibration is required if antenna is started at a temperature which rate sensors are not calibrated. After calibration the Antenna will restart.) Check active alarms - Check GPS and Gyro input. (GPS may use up to 10 minutes to get valid reading if system has been powered off for a long period.) - Az reference not detected ( Hall sensor) will give an alarm, If magnet is in place on AZ cogwheel – it may be related to defect hall sensor, located inside ASU, if faulty it will require ASU to be exchanged. Faulty setting of AZ home sensor offset value.
What to Check / to do Verify free movements with no special torque in all axes. (Antenna powered on so that motor breaks are off, verify free movement before antenna starts to initiate.) Observe antenna during initialisation. To check if system is performing calibration of sensors: Check JRAS: If status is = “Calibrating” wait 5-10 minutes for “Test 1” to calibrate rate sensors. If status is “Stabilising” enter “System -> regulation status” and open “View uC Trace” observe if “test 1” has started. If so wait 5-10 minutes for “Test 1” to calibrate rate sensors. Check JRAS status: If status is = “Calibrating” wait 5-10 minutes for “Test 1” to calibrate rate sensors. - If status is “Stabilising” enter “System -> regulation status” and open “View uC Trace” observe if “test 1” has started. If so wait 5-10 minutes for “Test 1” to calibrate rate sensors. - Check GPS - GPS information can be received either from own GPS located in ADE or GPS received via NMEA port on BDE. - In JRAS check c - Gyro, Check that NMEA cable is connected and that valid heading sentence is present. In JRAS check counter for valid Gyro input - If valid Gyro sentence is present on cable from Vessel, try to swap input connection: Tx+ and Tx- on input connectors NMEA In A/+ and NMEA IN B/Verify by manually performing procedure for calibrating azimuth offset values.

4.8 Polarization alarm troubleshooting In case of “regulator alert” alarm, check register 100 to see if polarization is the cause. This is done in the CLI. (telnet) Start by connecting to the BDE and use a telnet application to access the CLI. (Standard address is 192.168.0.2)
Log in with credentials user: cli password: telnet After logging in use command “rtr 100” to read register 100, this is a general alarm register and if returned value is: o 0 - All is well no alarm o 32 - The alarm is related to polarization o 96 - The potentiometer is not calibrated. (This can occur if calibration of potentiometer, “test 5”, have failed.)
(in example value “0” is returned meaning no error.)
4.8.1 Checking potentiometer readings A manual check of the potentiometer can be done by setting the antenna in hold mode. This is done by either going in to the pointing menu of the web interface or by entering the CLI command “pause”
Revision A 2012-08-06

Then one can run the transceiver to various positions using the “tilt value” command, value given in degrees. Normal span is from -37 to 144 degrees approximately.
The potentiometer reading can be read via the “rs 7” command which reports the unfiltered and unscaled value. Try moving the transceiver and read “rs 7” and see if the value changes. It should give a more or less linear curve. If the potentiometer is broken or the transceiver is stuck, typically this value will not change much. ( On current HW version 2.1, a polarization move of 1 degree in polarization is Average/approximately 5.7 units in register RS 7)
Revision A 2012-08-06

Jotron B120 Service Guide
The ASU has a pre-stored table of potentiometer readings for every 20 degree. This table is created during Potentiometer calibration, “test 5”. This Table is used to calculate the polarization error by comparing the value in the table to the current reading, The limit before rising a Potentiometer Alarm is 2 degrees. (200 in cli) The estimated polarization error can be read via test register 166.(cli command “rtr 166”)
The table is stored in a EEPROM (index 113-122) and is stored when running test 5. If test 5 fails the EEPROM table is cleared (all values set to -1). The EEPROM values can be read manually, CLI command rep 1 113, rep 1 114….. Values are displayed during start-up (might be difficult to start trace early enough to catch this, but running “test 25” will re-read and display EEPROM values ( use ”str 209 1” command first to avoid restarting). When plotting the EEPROM values they should give a more or less linear curve (decreasing). Values should decrease in steps of approx. 110 – 125. Ready for Command:rep 1 113 uc eeprom [113] = 2260 Ready for Command:rep 1 114 uc eeprom [114] = 2134 Ready for Command:rep 1 115 uc eeprom [115] = 2012 Ready for Command:rep 1 116 uc eeprom [116] = 1887 Ready for Command:rep 1 117 uc eeprom [117] = 1760 Ready for Command:rep 1 118 uc eeprom [118] = 1634 Ready for Command:rep 1 119 uc eeprom [119] = 1508 Ready for Command:rep 1 120 uc eeprom [120] = 1381 Ready for Command:rep 1 121 uc eeprom [121] = 1253 Note that the tilt command will work within the limits given by the test registers “R_POL_START_CDEG” and “R_POL_STOP_CDEG”. The control SW will implement unwrap. Running test 28 will run transceiver to end point.

4.8.2 Checking step motor current We have the possibility to monitor the current in the step motors. This is done from the cli running the rs command (rs = read sensor). rs 22 gives the current in the step motor This is just an unscaled adc value, but gives an indication of the current used. The measured current is the combined current to the step motors. The current depends on whether one or two coils are powered in the step motors. The step motors runs the following conditions. Sens motors: one or two coils (runs and holds in in half-step mode which, gives the best accuracy) Polarization motor: holds using one in order to minimize power consumption and runs using two coils in order to give maximum torque. The step motors will draw current when attached and the measured current will depend on whether the motors are running or only holding. The motors can be tested by setting the antenna in hold mode (in cli:”pause”) and running the step motors manually (in cli: “el value” or “tilt value”, value given as degrees). No motors attached rs 22 gives the value 0. Pol motor not attached (running sens motor) Holds step motor: fixed value approx 150 or 300 Running sens step motor: toggling between approx 150 and and approx 300 Sens motor not attached (running sens motor) Hold pol motor: approx 150 Running pol motor: approx 300 Both motors attached (not running sens motor) Holds pol motor: approx 300 /450 depending on elevation motor holdig one or two coils. Running pol motor: approx 450/600 Note: It is not possible to see if transceiver is stuck or not from reading the current, but at least one can see if there is any problem with the step motor cables or motor. At least when running the pol motor the measured value should be larger than the hold current. It should be possible to see if sensor box is moving, but then one must turn off tracking in elevation. ’ cli: pause(to enter hold mode) cli: str 21 0 cli: el value (to run sensor box) cli: rs 2 The value reported gives the elevation rate sensor which should change.
4.8.3 High elevation polarization error Note that for very high elevation (> 85 ) we can get polarization alarm if azimuth pointing is off. The normal satellite tracking does not work in the same way for very high elevation so here the B120 adjusts the azimuth based on gyro input. (For system release 2.11 this alarm occurs at 75 , but in the 2.11_Branch 3 the alarm threshold is increased to 85 .)

4.8.4 TEST REGISTERS Test register values are used to report or to control the MCSW. Test register values will be cleared after restart or get some default value. In order to permanently change parameters this must be done by changing code or some parameter can be change by writing to the EEPROM.
Test register 100
NAME
Explanation
R_ALERT_STATUS
105
R_ALERT_POL_CLEAR
166
R_DF_POL
If polarization alarm (bit 5 is set =32) If no potentiometer values in EEPROM (bit 6 is set = 64). Writing 1 to this register clears the polarization alarm. The SW will go on and ignoring this alarm. The value will be cleared after a reset. Important: Avoid transmitting when this register is set. Value given in [cdeg] and gives polarization error. Gives difference between measured value and reference value. The reference values are set during test 5. 1 The default threshold is 200 (2 )
The direct reading from the potentiometer can be read via the cli command: rs 7 This value should change linearly when rotating the transceiver. If potentiometer is broken or transceiver stuck the register will have a fixed value. In earlier SW releases (prior to 3.5) register 166 is not given in cdeg, and must be scaled up by 1.5. 167 R_POT Direct reading of potentiometer, only in v3.69 or later 209 R_SKIP_INITIALIZATION If set to 1, abort normal initialization, load eeprom values and goes directly to regulation mode. Normally test 5 will lead to a complete restart, but this can avoided. After a restart this register is cleared! 248 R_POL_START_CDEG Start value for polarization setting in cdeg 249 R_POL_STOP_CDEG Stop value for polarization setting in cdeg Read test register (rtr index). Write test register (str index value)
4.8.5 CHANGING THRESHOLD FOR POLARIZATION ALARM The threshold for polarization alarm is default +/-2 . This value is the default value. It is possible to modify this value by writing to EEPROM register 131 (sep 1 131 value for setting value and reading back by rep 1 131). The value will not be cleared after a reset. If the EEPROM value is -1 one it will use the default value (200). Important: Avoid transmitting when this EEPROM value is set above 200.

4.12.1 Fault finding Symptoms Defect CMU will cause BDE to ADE communication to fail, e.g. status in JRAS “no contact with pedestal” Quick check is to ping network units: ACC: default 192.168.0.2 BCMU Single Antenna: 192.168.0.5 ACMU Single Antenna: 192.168.0.14 ASU (Blackfin) : 192.168.0.15
4.12.1.1 Fault finding from BDE Connect PC to BDE Ethernet port in front on BDE or local/switch Ethernet port at the rear of the BDE. - Check if one can access the BCMU and /or ACMU. - If both CMUs are accessible it indicates that the CMUs are OK and that the problem lay elsewhere. If only BCMU is accessible it indicates that the issue may be: - Faulty ACMU HW or configuration - Faulty ACMU-BCMU configuration - Fail in Rx Chain between ACMU and BCMU - If no response when accessing ACMU nor BCMU, it may be due to: faulty BCMU HW or configuration - Faulty BDE Ethernet switch or Ethernet cables inside BDE - Try IP-connection to the Access controller: - If access fails the problem may be: Switch - Access Controller - Internal Ethernet cabling in the BDE. - IF OK it indicates a faulty BCMU and/or BCMU configuration.

4.12.1.2 Fault finding from ADE Enter the radome, connect to WLAN and verify access to the ACMU - Is it possible to access ACMU & BCMU - If only ACMU it indicates: - Faulty BCMU HW or configuration - Faulty ACMU-BCMU configuration - Fail Rx Chain between ACMU and BCMU - Observe ACMU LEDs, normal lighting ? - Verify Ethernet cabling between ACMU and ASU is connected, and that the ASU is not restarting the ACMU.
4.12.2 Cable Modem Exchange Procedure Work Flow 1. Physical replace CMU 2. Configure ACMU and BCMU NOTE! ACMU ASU supply voltage to the ACMU. ASU requires at start-up to detect physical Ethernet connection on its RJ45 connector. If no physical connection is detected during initialization ASU will continuously powercycle the ACMU. It is important during ADE Power-on/ Start-up that ASU Ethernet outlet is connected the ACMU or a Switch that powers the Ethernet. Otherwise the power to the ACMU will continuously be cycled making configuration of ACMU impossible.

1.
Observe that antenna initiates correctly.
2. Normal sequence should be after power on in the ADE: BDE indicator: Init/Operation is flashing yellow BDE indicator: Link/Antenna cal is shortly flashing green BDE indicator: Link/Antenna cal is flashing yellow/green This could take up to 3-4 minutes if the Jotron B120 has been switched off for more than [1] hrs. ADE Initialization (Approx. 1 minute) - Sensor box moves CW/Up towards end stop, when it reaches mechanical end-stop it will continue to move towards end stop for some additional time making a “hammering” noise, duration of this will depend on initial position of sensor enclosure when system is powered on. - Sensor Unit will move out of CW end stop and position itself at approx 0 degree Elevation angle. - Transceiver moves CW towards mechanical end stop, when it reaches end-stop it will continue for 1 sec “hitting” the end stopp, this will make a mechanical hammering noise. - Antenna dish move down in elevation to mechanical end-stop, Note that motor will make some extra noise when it reaches end stop. - XEL axis will move CCW to end stop, Note that motor will make some extra noise when it reaches end stop. - XEL moves to horizontal position - EL Moves to approx 0 degree - Sensor unit should now be in level both in EL and XEL direction - AZ moves CCW/CW( switches between CW and CCW every re-start) to detect reference. It will move approx 10 degree before it makes a temporary stop of 1 sec before continuing (This to detect AZ motor index readings). When Hall sensor detects the magnet the antenna will stop and rotate CW/CCW +360 degrees until the hall sensor detects the magnet. - Antenna initialization is finished and if BDE receives GPS and NMEA Gyro input it will point the antenna to the selected satellite. You will then observe the following on the BDE: Link/Antenna cal is flashing green Search/Tracking is flashing yellow This could last from 5 to 60 seconds assuming Blockage zone is not flashing yellow, no geographical obstructions (mountains, bridges etc.) or the signal level is sufficient (no rain fade or not at edge of coverage). Search/Tracking is flashing green Sat Lock/Tx-enabled is flashing yellow This could last from 10 seconds to 15minutes depending on e.g. the SNR seen by the VSAT Modem and the sea state. Sat Lock/Tx-enabled is green This will normally last very short assuming the modem is correctly configured and registered. Sat Lock/Tx-enabled is flashing green: VSAT is transmitting. Blockage zone is not lit. Alarm is not lit.
