Mechanical and Electrical Installation

Use 4 #10-32 mounting screws (included with the controller) to secure the unit to a standard
19" rack. The controller's back panel is depicted in figure 3.1.
The back panel contains ...
1) An IEC AC voltage input module with built-in fuse and line voltage select. Fusing
requirements and line voltage selection is described in section 3.1.
2) A removable, clamp style, 11 position connector (designated J1) that interfaces to ...
a) the antenna actuator position sense lines (antenna position sense connections are
described later in this section),
b) the analog receiver, modem or beacon receiver analog output voltage that is proportional
to antenna received signal strength (interface described in section 4.x),
c) the Autopol input (section xx),
d) and the Polarotor 3 wire servo polarization control device (section xx). Please refer to
section xx even if your system does not support polarization control.
Terminal 1 of connector J1 is labeled.
3) A removable, clamp style, 6 position connector (designated J2) to interface to the antenna
drive motor. The antenna actuator interface is described in this section. Terminal 1 of
connector J2 is labeled.
4) A DB-9 female connector (J3) for the SA-Bus compatible remote control interface.
Interfacing to the CONTROL-1500's remote control connector is described in the appendices.
5) Optional – A removable, clamp style, 5 position connector (designated J4) that interfaces to
a rotating feed powered by a DC motor that employs a potentiometer for position feedback.
This connector will only be present if the RC2KPOL option is installed in the controller. The
RC2KPOL option is described in section xx. Terminal 1 of connector J4 is labeled.
6) Four potentiometers labeled AGC1 Gain, AGC1 Offset, AGC2 Gain, and AGC2 Offset. The
adjustment of these potentiometers is described in section xx.
7) A circuit breaker to protect the antenna drive. When a circuit breaker of this type trips, it
will protrude from its mounting bezel. To reset a circuit breaker, turn the power switch off,
wait a few minutes for the circuit breaker to cool down, then depress the breaker so that it
latches and is even with the bezel.
