Configuring the Radio Control Board
The radio control board provides the audio interface, level set, audio mixing, local
telemetry (key up and CW ID) generation, serial radio control interface, extra user
programmable open collector outputs. One RCB is required for every radio or VOIP
computer in the system. Each RCB is configured to have one of several "personalities"
including a repeater, RF link, remotely controlled base station, or VOIP computer.
Basic Checklist
Make sure all RCB board jumpers are properly set.
JU1 - RX Port Select
You MUST have one (and only one) jumper installed in this block. It must correspond
to the port you want to assign this board from 0 to 7.
No two boards can have the same rx port select value.
JU2 - CPU Address
You MUST install jumpers in the address header to match the port assignment. This
should be the same vale as the jumper installed in the Rx Port Select information above.
