Installation DAC-2202 Antenna Control Unit
4-2
4.5. Install the Terminal Mounting Strip (TMS)
Install the TMS in the rear of the standard 19” equipment rack or other suitable location.
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.

4.6. Install the Base Multiplexer Panel
If your antenna system includes a base multiplexer panel, install the panel in the rear of the standard 19” equipment
rack or other suitable location.
4.7. Terminal Mounting Strip Connections and Jumper Settings
4.7.1. 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

Jumper Selection
JP1 – JP4 are 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.
JP2 SW2 (blockage & RF radiation hazard output) - Used to control dual antenna arbitrator, in
dual antenna configurations, and provide TX Mute control to the Satellite Modem. Default is
SHORTED when blocked.
JP3 SW3 (reserved) - Reserved for future use.
JP4 AGC (external AGC input) - Pull-up for external AGC input from Satellite Modem which is
used to a positive satellite Network ID when the modem is on the correct network (therefore the
antenna is on the correct satellite). Default is SHORTED.
NOTE: This jumper MUST be
removed when using iDirect 3000 & 5000 Series modems.
JP5 Voltage Output Select - Select 12VDC or 24VDC. Default is 12VDC.
4.7.1.2. J1 “Modem Console Port” connector
FCC compliance connection to an iDirect Satellite Modem can be made very easily by connecting a
Straight Serial RJ-45 cable from the J1 “Modem Console Port” connector on the Terminal Mounting
Strip to the Console port on the iDirect Modem. Your modem must be set
If your modem is Open AMIP compatible and you wish to use it in an Open AMIP configuration you
will use an Ethernet patch or cross-over cable as is appropriate to connect to your LAN.
