5. Connect remote control interface. (optional)
For a full listing of 5500's extensive remote control provisions, refer to Remote
Control Interface Programming on page 2-42.
Optically-isolated remote control connections are terminated in a type DB-25
male connector located on the rear panel. It is wired according to Figure 2-2. To
select the desired function, apply a 5-12V AC or DC pulse between the appropri-
ate REMOTE INTERFACE terminals. The () terminals can be connected together
and then connected to ground at pin 17 to create a Remote Common. A current-
limited +12VDC source is available on pin 25. If you use 48V, connect a 2k
10%, 2-watt carbon composition resistor in series with the Remote Common or
the (+) terminal to provide current limiting.
In a high-RF environment, these wires should be short and should be run
through foil-shielded cable, with the shield connected to CHASSIS GROUND at
both ends.
