also just confirming that the
hm2_7i92.0.encoder.03.input-index doesn't change state.
I can see a few options to change.
should I change to the IDX/ input?
or should I change the value of resistor?
You should measure the voltage at the prox output/index input
in both states. It should be lower than .7V in one state and
higher than 3V in the other.

hey Peter
using a 7i77 mesa card
I just tried my PNP sensor now i have wired up the ground and 5v
correctly
and have the signal wire into the pin 7 which is the index channel. I
have also changed the jumper for the index channel to single ended
operation.
it doesn't work... what am I doing wrong?
also I am testing by using the command setp hm2 7i92
encoder.03.index.enable 1 (etc command probably is wrong here as I am
working from memory but it changes the pin color in hal configurator)
I can see the proxy is switching as the led turns off and on at the back
of
the thing
for reference here is the link to the proxy I am using

You can check the index state directly in hal by monitoring
hm2_7i92.0.encoder.0N.input-index (N is the encoder channel
you are testing) I think this is inverted from the pin state.
Note that if you do not have the stiff (270 Ohm or so) pull down
resistor, the prox output will always be high (around 5V)
