Antenna Control Unit Connections
Figure 1-1 Rear Panel DAC-2202 ACU
3.12.4.1.
Antenna Control Serial Cable
Connected the Antenna Control Serial Cable from the Base Multiplexer to J4A on the DAC-2202.
3.12.4.2.
ACU to Terminal Mounting Strip Connections
Connect the TMS to the ACU.
1.
Connect the 25 pin ribbon cable from the Terminal Mounting Strip to J1 “Ships Gyro” DB25
on the rear panel of the ACU.
2.
Connect the 9 pin ribbon cable (or NMEA serial cable) from the Terminal Mounting Strip to
J2 “NMEA” DB9 on the rear panel of the ACU
3.12.4.3.
RXIF Signal Input to the ACU
Connect the RXIF cable from the Base Multiplexer to the J6 “RF IN” connector on the rear of the
ACU. This input provides satellite signal to the tracking receiver inside the Antenna Control Unit.
3.12.4.4.
RXIF Input to the Matrix Switch
Connect the RXIF cable from the “RF OUT” on the rear of the ACU to the matrix switch or other
distribution device.

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

3.12.5.1.
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.
