9711-92 Ku-Band TXRX

Installation

3-29

3.6.5.3.

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 ACU.

3.6.5.4.

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.

3.6.5.5.

Ethernet Connection to the ACU

The Ethernet connection can be used to Monitor & Control the antenna through the ACU 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.

3.6.5.6.

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.

3.6.6.

Radio Control Serial Cable

If desired, connect the radio control serial cable from the base multiplexer to the COM port of a customer

furnished computer.

3.6.7.

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

3.6.7.1.

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.
