Yes, LSCOMM is limits and homes.
You can probably use the 5v outputs on the ICM to power the optical switches. No external supply needed if they don't draw much current.
You can ground LSCOMM and provide the pos signal from the switches. However, all inputs and homes must operate in the same manner. You can't have limits one way and home another.

Thanks, Steve
Ok nowI think I am starting to understand this.
So if I use onboard ICM 2900 5V to power the Optical limits I would run a wire from one of the GND terminals on ICM to LSCOMM Then run ICM 5V+ to the limits NC and when the limit trips it will disable thru Mach?
Or does it disable the enable for that axis on the ICM?
And looking at the Opto wiring diagrams in the links you provided. Are the resistors shown a circuit within the ICM or is that something we need to add.
I wish there was some good Documentation for the functionality of the ICM 2900.
Oh by the way Wilde Racing I hope you do not think I am high jacking your thread. I figure the best place to ask these question is here, because you need the same answers.
