Here is the question and reply I just received from Ajax.
Captain Midnight,
Hi,
I am trying to install a Whitehorse probe. I am running Mach3 on the DC310B. The manual says to connect to H3 pin 6 and pin 5 on the MPU11. It says that should be input 481. My MPU11 I/O map doesn't have that input listed. It starts at 769 and goes to 786. To verify to connection by running CNC11, Pin 6 lights up LED 769. I tried setting the Ajax Configuration Utility to Probe Input 769 and 481, but that will not light the Probe LED on the Mach3 diagnostic screen. My MPU11 I/O seemed to mapped differently than the manual's directions. I don't seem to have an Input 481 on my MPU11.
How can I resolve this?
Thank you
Captain Midnight

The Mach3 software has that input mapped differently than the CNC11 software. If you are trying to verify the operation in CNC11, when you press ALT+I, you will need to press F12 until you see inputs 769 thru 771. You could also use ModBus to look at input 481 in the Mach3 software to verify it is working. This is explained in the manual. Thanks.
