APPENDIX 8: SERIAL COMMUNICATIONS
A8.01 Cables and Switch Settings for 2 and 4 Wire
The CCM communicates with the TSC 3000 (touch screen HMI panel) using RS 485 (2 wire, half duplex). When a CNC
controller is used in place of the TSC the CCM can be reconfigured for RS 422 (4 wire, half duplex) if supported by the
CNC. RS 422 is normally full duplex but the CCM only supports half duplex. RS 232 is not directly supported.
Converters are available from various sources to convert RS 232 to RS 485/422. When possible, the 4 wire configurationisIt
is recommended to use the 4 wire configuration when possible for easier troubleshooting. The serial communication
port of the CCM is provided with 3KV isolation from the rest of the plasma supply circuitry.
