Motor Control Connector, J5
J5, located on the right side of the back panel, is a DB-50R connector identified as the MOTOR
CONTROL connector. This connector acts as the antenna motion control port of the RC2500-ANDREW
ACU .
The port consists of 10 solid-state sinking drivers and a +12 Volt source for driving the optical isolator
inputs of the Andrew outdoor unit. The individual pin definitions as well as their mating connection at the
APC300 are shown in the table below. For additional information on this port examine Figure S-3,
RC2500 – ANDREW BLOCK DIAGRAM, OUTPUT CIRCUITRY Sheet 2.
