3.7.6. Radio Control Serial Cable
If desired, connect the radio control serial cable from the base multiplexer to the COM port of a customer
furnished computer.
3.7.7. Terminal Mounting Strip (TMS) Connections
Connect the Ships Gyro Compass input to the appropriate screw terminals on this strip. The satellite
modem must also be connected to provide compliance with FCC Order 04-286 and WRC-03 Resolution
902.
There are several functional connections that may be made on the TMS connectors. Although you may
not need to make all of these connections, they are listed here for clarification during the installation
process. Connect the 9 pin ribbon cable from this PCB to J2 “NMEA” DB9 on the rear panel of the ACU.
Connect the 25 pin ribbon cable from this PCB to J1 “Ship Gyro” DB25 on the rear panel of the ACU.
CAUTION - Electrical Shock Potentials exist on the Gyro Compass output lines.
Assure that the Gyro Compass output is turned OFF when handling and
connecting wiring to the Terminal Mounting Strip. DO NOT HOTPLUG THIS
CONNECTION
3.7.7.1.
Jumper Selection
JP1 – JP4 are used to couple in pull-up resistors for the below listed functions. JP5 selects the DC
voltage output on TS4.
JP1 SW1 – This output would be used for below decks Band Select - to control a band
selection switch or tone generator. Default is OPEN .
Shorted provides DC Voltage output (determined by JP5 setting) on the SW1 screw terminal to
supply voltage to a tone generator or band select switch.
Open provides continuity output (short to ground or open circuit) on the SW1 screw terminal to
control devices which have their own power source.
JP2 SW2 (blockage & RF radiation hazard output) - Provides TX Mute control to the Satellite
Modem for FCC compliance in all VSAT systems. It is also used to control antenna switching via
a dual antenna arbitrator in dual antenna configurations.
Default is SHORTED when blocked.
The Blocked/Unblocked logic state can be reversed by including SYSTEM TYPE 0016.
Shorted provides DC Voltage output (determined by JP5 setting) on the SW2 screw terminal to
supply voltage to the satellite modem when the modem requires DC Voltage to Mute
transmission. In dual antenna configurations this used for dual antenna arbitrators that require
DC Voltage to switch. This hardware connection is also routed to the Console and OBM RJ45
ports.
Open provides continuity output (short to ground or open circuit) on the SW2 screw terminal to
satellite modem when the modem requires continuity control (short or open) to Mute
transmission. In dual antenna configurations this used for dual antenna arbitrators that require
continuity control (short or open) to switch. This hardware connection is also routed to the
Console and OBM RJ45 ports.
JP3 SW3 (reserved) - Reserved for future use. Default is OPEN .
JP4 AGC (external AGC input) - Input from Satellite Modem which is used to provide a
positive satellite Network Lock (RX Sync) ID when the modem is on the correct network.
Default is SHORTED . The Locked/Unlocked logic state can be reversed by including SYSTEM
TYPE 0128.
Shorted provides a pull-up DC Voltage input (determined by JP5 setting) into the ACU when the
modem supplies a continuity output. This hardware connection is also routed to the Console
and OBM RJ45 ports.
