DIP Switches (S1-S4) for Communication Settings
The circuit board inside the CCU chassis has four DIP Switches, S1
through S4, for setting the baud rate, odd/even parity, and enable or
disable receive/transmit for channels one through eight. Each switch
supports two channels. Switch S1 sets channels 1 and 2, switch S2 sets
channels 3 and 4, switch S3 sets channels 5 and 6, and switch S4 sets
channels 7 and 8 (COM1 and COM2). Switch positions 1 and 2 set the
baud rate for channels 2, 4, 6, and 8. Switch positions 4 and 5 set the
baud rate for channels 1, 3, 5, and 7. Switch positions 3 and 7 set the
parity (even, odd, none) for channels 2, 4, 6, and 8. Switch position 6
sets the parity (even or odd) for channels 1, 3, 5, and 7. No parity is not
available for channels 1, 3, 5, and 7.
