3.7.3.
1. Attach the TXIF coax from the antenna to the TX Connector on the Base Multiplexer Panel.
Connecting the ADE IF Coaxes
2. Attach the RXIF coax from the antenna to the RX Connector on the Base Multiplexer Panel.
3.7.4.
Connect the TXIF coax from the Base Multiplexer Panel to the Satellite Modem TX Output.
Connect the Modem TXIF Coax
3.7.5. Antenna Control Unit Connections
Figure 1-2 Rear Panel DAC-2202 ACU
3.7.5.1. Antenna Control Serial Cable
Connected the Antenna Control Serial Cable from the Base Multiplexer to J4A on the DAC-2202.
3.7.5.2. 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
3.7.5.3. 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.
3.7.5.4. RXIF to the Satellite Modem
Connect J7 “RF OUT” on the rear panel of the ACU to the RX Input connector on the Satellite
Modem. The RX signal level of the J7 output of the ACU is approximately unity with J6 input due to
an in internal amplifier.
3.7.5.5. Ethernet Connection to the ACU
The Ethernet connection can be used to Monitor & Control the antenna through Antenna Control
Unit via the internal web pages, by use of DacRemP IP or via an Ethernet connection through a
router/switch/hub to an Open AMIP compatible satellite modem. Use an Ethernet patch cable to
make your desired connection to the Ethernet connector on the rear panel of the ACU.
3.7.5.6. M&C Connection to the ACU
If you wish to use a computer to Monitor & Control the antenna through the Antenna Control Unit
there are two possible connections that can be made. One choice is a serial connection from J3
“M&C” connector on the rear panel of the ACU to a COM port on the computer using a serial
extension cable. Another choice is to connect the “ETHERNET” connector on the rear panel of the
ACU to a LAN connection on the computer or hub using an Ethernet crossover cable.
3.7.6.
If desired, connected the Radio Control Serial Cable from the Base Multiplexer to the COM Port of a
Customer Furnished Computer.
Radio Control Serial Cable
3.7.7.
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.
Terminal Mounting Strip (TMS) Connections
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.
