Remote
Control Interface Programming
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 13 to create a Remote Common. A current-
l12VDC source is available on pin 25. If you use 48V, connect a 2k
Ω
±
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.
