Bridgeport Series 2 Interact 4 Retrofit

Yes sorry also have 24V supply to the 7i76, field power led is on.

7I76 W1, W2, W3 all in left hand position?

correct all left

Note that following errors in the stepgen are most likely caused
by incorrect PID P values (this can happen if you change the with
servo thread with pncconf)

P should be 1/Servo_Thread_Period or 1000 for a 1 ms servo thread.

Much appreciated PCW, have changed to 1ms and no more following error. Still no pin availability however, but I will come back to that one day.

Have started getting the 7i92/7i85 going with the 7i84 io board initially. Flashed the 7i92_7i85xD.bit, connected the 7i84 to serial 0 and hooked power to everything. Made a simple HAL file attached with e-stop as an input and linuxcnc loaded up perfectly. I am however getting funny behavior where the input-00 is held high without anything connected to the pin (can be seen in the screenshot of HAL Config). Toggling 24V to the input pin doesn't change the pin state. Is there anything I have done wrong in the HAL definition?

cheers,

No, I don't think you can affect that in HAL

Looks like a bad or damaged 7i84.

All 7I84s must pass a loopback test (output to input test)
that tests all inputs and outputs, so whatever is wrong s something
that's changed on the card.

BTW, I tested a 7I92+7I76 configuration with 7I92_7i76x1D firmware
And saw no issues so that also look like hardware.(cabling? ESD?)
