Notes:
1. Serial terminator DIP switches (S1) and Serial ID DIP switches (S2) are not used for
discrete-only CNC connections.
2. The CNC must provide separate inputs and outputs for each XPR plasma power
supply. Sole exceptions are PLASMA START+/- and HOLD+/-. These can be wired
in parallel from one set of CNC outputs to all XPR plasma power supplies.
