Installation

9711-92 Ku-Band TXRX

3-32

•

Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations when the antenna is
mispointed by 0.5 degrees, or more, and keep it muted until the antenna has been within 0.2 degrees of peak

pointing to the satellite for a minimum of 5 seconds (FCC part 25.221 & 25.222 TX Mute requirement).

3.6.7.5.

TS2 Synchro Gyro Compass Input.

Use the R1, R2, S1, S2 and S3 screw terminals to connect the Synchro Gyro Compass to the ACU.

3.6.7.6.

TS3 Step-By-Step (SBS) Gyrocompass Input.

Use the COM, A, B and C screw terminals to connect the SBS Gyrocompass to the ACU. Some SBS

Gyro distribution boxes have terminals which are labeled S1, S2 & S3 instead of A, B and C.

3.6.7.7.

TS4 Power

•

VREG

Screw terminal is used to provide a regulated DC operating voltage to ancillary equipment. Voltage out is

dependent upon which terminal mounting strip assembly is provided. 126865-1 supplies 8Vdc @ 1Amp, while the

126865-2 assembly supplies 5Vdc @ 2Amps.

•

GND

Screw terminal is the ground reference for the regulated and unregulated power terminals.

•

12/24

Screw terminal is commonly used to provide operating voltage to an external GPS, Dual Antenna Arbitrator

or other below decks tone generators or switches. Voltage output is based on the T.M.S assemblies JP5 jumper
settings.

3.6.7.8.

TS5 NMEA A/B, GPS output.

•

RxA- and RxA+-

screw terminals, which are defined as the NMEA A connection is used to connect to the ships

Gyro Compass (Heading). The NMEA0183 compliant inputs are then connected via a 9 pin ribbon cable to the

ACU’s J2 NMEA communications port. A GPS (Latitude and Longitude) input may also be connected, but is not
required because there is a GPS device already installed in your antenna..

NOTE:

If you connect a ships GPS to

the terminal mounting strip, you

MUST

disconnect the GPS antenna on the antenna pedestal.

•

RxB- and RxB+

screw terminals, which are defined as the NMEA B connection is used to connect to the ships

Gyro Compass (Heading). The NMEA0183 compliant inputs are then connected via a 9 pin ribbon cable to the

ACU’s J2 NMEA communications port. A GPS (Latitude and Longitude) input may also be connected, but is not

required because there is a GPS device already installed in your antenna.

•

TxA-

screw terminal is used to provide a Pseudo GPS (GGA and GLL formats) output to other system components

such as a Satellite Modem.

3.6.8.

Other BDE connections

Connect your other Below Decks Equipment (ie, telephone, fax machine and computer equipment) to

complete your configuration.

3.7.

Final Checks

3.7.1.

Visual/Electrical inspection

Do a visual inspection of your work to assure that everything is connected properly and all cables/wires are

secured.

3.7.2.

Electrical - Double check wiring connections

Double check all your connections to assure that it is safe to energize the equipment.

3.8.

Power-Up

Verify that all shipping straps and restrains have been removed prior to energizing the antenna.

When all equipment has been installed, turn ACU Power and Antenna power ON. The ACU will initially sequentially

display:

“SEA TEL – MASTER and DAC-2202 VER 6.xx” followed by,
“SEA TEL – RCVR and SCPC VER 5.xx” followed by,
“SEA TEL – IO MOD and COMMIF VER 1.xx” followed by,
“SEA TEL – REMOTE and INITIALIZING”.  After initialization, the bottom line of the remote display will display

the antenna model number and the software version from the PCU.
