Sanity check, 7i92 to mx4660 + relay board?

I am planning a new Router build with an AVID benchtop (dual drive on one axis) unit with an ATC spindle from CNCDepot with Hitachi VFD.  I have lots of experience with Linux, LinuxCNC and electronics.  I am new to using mesa cards.  I don't expect to need much if any hand holding however I would like a sanity check on my proposed setup.

The 7i92 DB25 to MX4660 DB25 should get me most, if not all, the IO I need to get the basic machine up and running.  For the stuff that does not fit in the DB25 the MX4660 has a second 26 pin connector for 4 more inputs and 4 more outputs.  Since these 26 pin connectors appear to have different pinouts I will have to make a custom cable or use a couple of 26 pin breakout boards.

I plan on keeping the spindle control analog with feedback and monitoring  via an rs485 interface.  USB converter or built in depends on the computer I pick to run it.

If I run out of outputs for things like air blast or coolant pump I also have an 8 ch relay board that I would use the other 8 GPIO on the 7i92 26 pin to drive. It has ttl style inputs (TI uln2803a input chip)


Thank you.


 

Thank you, I did find the mx4660 firmware. I think it's going to work just fine for what I need.

My 7i92 got here the other day, I will be able to play with it in a few weeks after a cross country road trip. Still waiting for my electronics and steppers to arrive as well. The main machine is 15 weeks out too.
