I now have the probe installed and functioning properly, but it still won't light the LED on the diagnostic screen. How come?

Help this man.

I am connected to pins 6 and 5. The probe functions, but it won't light the LED on the diagnostic screen. How can I correct this?

When connecting a probe, do you have to set the ports and pins?

Thank you for the reply.

My probe is a simple contact. I hooked it up to pin 6 and pin 5. I tested it with CNC11, and it lit the proper LED. When I run Mach3 it won't light the LED on the diagnostic screen, so I'm not sure what to try next to correct it.

Does the probe funtion need to be activated some way, like setting up a brain, or is it ready to work? I can't get my probe to light the LED on the Mach 3 Diagnostics page.
Also, on the MPU11, there are 4 probe input choices, which one is the high speed input?

I connected my probe to the probe input on the MPU11. Verified wiring. When tripping the probe, it doesn't show on the Mach 3 diagnostic screen. What am I missing?

I connected the probe, trying all of the probe inputs on the MPU schematic. MPU11 diagnostic screen comfirms contact. I entered the number into plugin configuration per Ajax Mach Operators manual. Set ports and pins. Restarted. Mach doesn't see probe input. What steps should I take next?

The manual states that I can use the high speed probe input channel 481. What pin number would that be. It is not listed in the MPU11 I/O Map.

Thank you.
