5-29
EAR Controlled - ECCN EAR99
5.5.3.13. J12 Aux 232
Auxiliary wired RS-232 connection. Wiring is:
Pin 1 - GND Ground
Pin 2 - Aux IN1 Modem Lock Input 1 - See modem setup chapter.
Pin 3 - Aux IN2 Modem Lock Input 2 - See modem setup chapter.
Pin 4 - GND Ground
Pin 5 - SW1 Blockage/Modem Mute Output 1 - See blockage &
modem setup chapters.
Pin 6 - SW2 Blockage/Modem Mute Output 2 - See blockage &
modem setup chapters.
Pin 7 - SW3A Dry Contact set 2 - Dry alarm contacts used to provide
(programmable) alarm output to other
equipment/systems. Switched outputs have ability to use
4.7K pull up or Pull Down and can provide Current sink of
0.5 amps max. Contacts are
Normally Open for No Alarm
state and are Closed/Shorted when the programmed
alarm state exists.
Pin 8 - SW3B

5.5.3.14. J13 NMEA 0183
NMEA 0183 I/O connections. The +12 VDC output is only intended to power a very low
current consumption device, do NOT exceed
125ma MAX. Wiring is:
Pin 1 RX+ NMEA
Pin 2 RX- NMEA
Pin 3 TX- NMEA
Pin 4 N/C
Pin 5 GND
Pin6 N/C
Pin 7 GND
Pin 8 TX+ NMEA
Pin 9 +12 VDC ( 125ma MAX )
If your NMEA 0183 Gyro Compass outputs RS-422:
•
Connect its’ TX+ output to J10 pin 1 (RX+)
•
Connect its’ TX- output to J10 pin 2 (RX-)
If your NMEA 0183 Gyro Compass outputs RS-232:
•
Connect its’ GND output to J10 pin 1 (RX+)
•
Connect a jumper from pin 1 to J10 pin 5 (GND)
•
Connect its’ TXD output to J10 pin 2 (RX-)
