Serial Ports
Hypertherm CNCs support two serial ports that can be set for either RS-422 or RS-232 communications. Both serial
ports are set to RS-422 at the factory. To change either serial port to RS-232, you must change a jumper setting on the
serial isolation board that is inside the CNC. The jumper positions are clearly marked on the board.
The serial ports in the CNC are specifically designed to operate with a standard nine-pin serial port connector. The
following table provides specifications for these ports:
CAUTION

compatible devices.
