I have customer who has a Mazak Laser with L controller. They are trying to setup CNC communications and getting an alarm upon punching out. They tried to call Mazak for help yet no one has called back.

The alarm is 301 which means nothing to me. If someone has a clue or even a list of alarms codes, please fax it to me @ 619-461-5918.

Also, any wiring diagram would be helpful too. We have wired the cable up to use hardware flow control but maybe this is related to the alarm?
