Notes:
1) For single system installations set Serial ID (S301), and Machine Motion (J303) 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.
3) Use only the first four dipswitch settings, they are the same as on the 141030 control
board.
4) If a Hypertherm Automation controler 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 18 of 19 for more details.
