What type of laser shutter is it (make/model). What input signal does it need to actuate? What motion controller do you have connected to the 7602?
Some motion control cards have general purpose digital I/O pins that can be set to output TTL compatible signals that might be used to control your laser shutter.
In any case, if the laser presents a safety hazard to personnell, you should add a hardwired E-STOP button to close the shutter in case of emergency (and to disable motion too)

The 7342 motion controller has a 2nd 68pin connector that has 32 general purpose digital I/O's on it, TTL compatible, up to 24mA sink/source.
You would probably need the 68 pin mating cable for it and some type of 68 terminal breakout card with terminal blocks to connect your wiring to for your external devices.
There are more details in the manual here:
https://www.ni.com/docs/en-US/bundle/373454a/resource/373454a.pdf
I never have used an NI motoin controller, not sure how the hardware/software is set up to access and control or read the digital I/O pins.
Now that we know what controller card you have, maybe someone from NI can suggest the specific cable and breakout card part numbers and how to access the I/O.
What software and version numbers do you have (programming envirnmont, motion control software, DAQ and MAX)?

Hi,
The MID 7602 gives you access to any of the signals from the Motion IO connector of your motion controller. It sounds like for your application you will need to access the Digital IO connector from your motion controller. Like AnalogKid2DigitalMan mentioned the second 68 pin connector has Digital IO lines, to access them you will need a 68 pin break out box, like the SCB 68.
I hope this helps.
Have a great day.
