This is a picture of all the connection on it.
They are in German but from top left it goes like this:
first row - OUT (Programmable Logic Controller - PLC), SAFETY SWITCH (big red button to put anywhere at hand), IN (PLC), MILLING MOTOR, SAFETY SWITCH (IR or some other proximity sensor)
second row - CAN bus, RS232, Analog(for jostick)
third row - axes output
So far I have used the RS232 port to send info from PC to controller.
So to which port do I put my RS232 cable that come from a computer on which I will install demo Mach3?
I would just try it but the controller box is still in Germany (not being repared).
Now to find out how to put a picture here
