For serial RS-422 multi-drop (multi-system) addressing, refer to XPR serial RS-422 multi-drop (multi-
system) addressing in the CNC Communication Protocol for the XPR Cutting System (809810).
■
For information about signals and protocols, refer to XPR serial RS-422 communications and Serial
RS-422 and EtherCAT commands in the CNC Communication Protocol for the XPR Cutting System
(809810).
■
To use Arc Voltage Control (AVC) with a serial RS-422 cutting system, connect pin 5 and pin 6 to J4
on the expansion PCB to access the estimated arc voltage. For information about how to configure the
arc voltage output scale through serial or EtherCAT, refer to the CNC Communication Protocol for the
XPR Cutting System (809810).

Hypertherm recommends a minimum distance of 1 meter (3.3 feet) between the plasma power supply
and other system components, or between the plasma power supply and an obstacle.

1. Remove the rear panel of the plasma power supply.
2. Put End A of the serial RS-422 cable through the hole in the bottom of the rear compartment in the
plasma power supply.
