RC-85 Repeater Controller Owner's Manual

Wiring to Your Controller

The various interface signals to the controller board may be connected using the
supplied mating connectors. Connector J1 uses the white 4 pin housing with the
large crimp connectors. Connectors J3 and J4 use the 8 and 14 pin red housings
with the small gold crimp connectors. It's a good idea to carefully solder the
connectors after crimping them, being careful not to let the solder flow to the
flexible portion of the pin. The pins may be inserted into the appropriate
housings. Carefully install them so that the small clip on the pin can latch onto
the square hole on each position of the housing (see diagram below).

Setting DIP Switch Options

Switch settings on the RC-85 controller board select high or low true sense for
the COS and PTT signals (see below). It's now necessary to set the switches
correctly to properly control the repeater. Switch 1 selects COS sense and switch
2 selects PTT sense. Assuming you don't have a control receiver connected yet,
switch 3 must be set ON so that the controller doesn't think that a control
receiver is active, therefore grabbing the Touch-Tone decoder. The other
switches should be left off for now. Chapter 8 provides details of switch
selections for the various options.

Setting Audio Levels

Several of the audio levels to the transmitter and phone may be adjusted using
on-board pots. The levels of the speech synthesizer and tone generator are fixed,
and the receiver audio levels (repeater and link receivers, R1 and R2) should be
adjusted to match the speech synthesizer level. The phone level to the
transmitter (R3) should be adjusted during a phone patch. The transmitter
audio output level from the controller is then fixed, and the audio gain and
deviation controls in the transmitter should be used to adjust the overall
transmit level.
