I’d like to set up a laser enclosure with an interlock switch on a laser marking system (required per my company’s EHRS policy). I noticed there is an option in EZCAD for this, DOOR IO, that can be linked to a port such that the laser won’t fire unless the door is closed. How can I wire up an interlock switch to an available input port? Are these other digital inputs the unlabeled pins on CON4?
