Notes:
1) For single system installations set Serial ID (S301), and Machine Motion (J300) as shown in Unit 1,
jumpers J104 and J105 must be closed.
2) On multi-system installations refer to the illustration. Jumpers J104 and J105 are left open on all
systems except for the very last system where they are in the closed position. Termination resistors (120-ohm) or
termination jumpers must be installed/set at the CNC for each of the RS-422 RX and TX signal pairs.
A
3) If a Hypertherm Automation Controller is being used, and there are intermittent communication failures
(PS Link Failure), try removing the jumpers on J104 and J105 on the control board, and the termination jumper
(J6 or J8) on the serial isolation board in the controler. Only remove the termination jumper on the
serial isolation board that is connected to the HPR power supply. See sheet 19 for more details.
