Troubles to get started with SD240 Retrofit

INDEX+ input (encoder disconnected)
changes the state of the hal index pin (hm2_7i80.0.encoder.00.input-index for X)

No it does not change in HAL-Show, it stays high (yellow) even if I short ENCX0 with GND (PIN on the 7i33)

And Sorry, I mixed it up- the jumpers W1-W4 are set to UP position so TTL/RS-422  sorry!

Not sure what you mean here, to me you seem to be saying  hm2_7i80.0.encoder.00.input-index changes
when you ground the INDEX+ pin but then it does not change.

2. Leaving the TTL option enabled, can you check that grounding the INDEX+ input (encoder disconnected)
changes the state of the hal index pin (hm2_7i80.0.encoder.00.input-index for X)

 

This was just a copy of your questions- sorry, the "2" is missing in my copy and below I wrote the answer to the question you asked.

OK that indicates either a problem with the 7I33, the connecting cable, the FPGA card
or the firmware.

Note that this test will only work if the 7I33 is jumpered for TTL encoder mode.

Ok, hope I understood correctly- I disconnected the X-encoder, set the jumper W4 DOWN to TTL and shorted the pins ENCX0 and GND of the X-encoder.
The status in HAL-Show for the hm2_7i80.0.encoder.00.input-index for X did not change, stayed high (yellow).
(I have set the jumper W4 back to UP before reconnecting the X-encoder)

OK it should be possible to debug this step by step:

First what FPGA card and what firmware is being used?
