Installation
ST94-21 C/Ku-Band TVRO
3-26
3.11.1.
Connecting the ADE AC Power Cable
Connect the AC Power cable that supplies power to the ADE to a suitably rated breaker or UPS.
3.11.2.
Connecting the BDE AC Power Cables
Connect the AC Power cables that supply power to the Below Decks Equipment (ACU, Satellite Modem,
phone, fax, computer and all other equipment) to an outlet strip fed from a suitably rated breaker or UPS.
3.11.3.
Connecting the ADE IF Coaxes
Attach the RXIF coax from the antenna to a shorter section of coax to reach the RX Output of the Diplexer
Box, inside the ship but near the antenna. Then attach the long section of coax (200 feet min) coax from the
RX Input of the Diplexer Box, to the RX Connector on the Base Multiplexer Panel.
3.11.4.
Antenna Control Unit Connections

3.11.4.1.
Antenna Control Serial Cable
Connected the Antenna Control Serial Cable from the Base Multiplexer to J4A on the DAC-2202.
3.11.4.2.
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
3.11.4.3.
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.
3.11.4.4.
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.
3.11.5.

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
3.11.5.1.
SW1 - Band Selection control output.
This output is used to control below decks tone generator(s), or coax switch(s), for band selection
functions. The band selection control output is driven by the band selected in the MODE –
TRACKING display.
