Remote Control Connections
40 As an alternative to local operation, the equipment can be operated from a remote position using a
PAE 3000V2 Series Remote Control Unit (RCU). Connections to the RCU are made from the radio’s
rear panel 9-way D-type remote connector CN5 (see Fig. 4).
41 The pin-out of the remote connector is detailed in Table 3-6. Pins 1 to 4 and 9 are used by all
models; pins 5 and 6 by transceivers and receivers only, and pins 7 and 8 by transceivers and
transmitters only.
42 When making connections to rear panel D-type connectors, and in order not to compromise the
equipment’s Electromagnetic Compatibility (EMC), users must:
❏
use a D-type connector that has a screened cover.
❏
use screened multi-way cable, with the cable’s screen connected to the connector’s shell or
body.
