SWITCH SUMMARY
The 6K Main Board has two switch assemblies, S1 and S2.
S1 is a momentary pushbutton switch used to initialize the controller. The procedure that must be
used to initialize the controller is described later in this manual.
S2 is a 6-pole dipswitch array. Five of the switches are used to invert the sense of logical input
signals. The sixth switch is used for special functions.
The five sense-reversal switches are described as follows:
DIP SWITCH #1 -
Inverts Receiver #1 COR Input
DIP SWITCH #2 -
Inverts Receiver #2 COR Input
DIP SWITCH #3 -
Inverts Receiver #1 CTCSS Decoder Input
DIP SWITCH #4 -
Inverts Receiver #2 CTCSS Decoder Input
DIP SWITCH #5 -
Inverts Transmitter PTT Output
A switch in the ON (closed) position means the input is "low" active. A switch on the OFF (open)
position means the input is "high" active. Unused switches should be placed in the ON position.
