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 https://www.aliexpress.com/item/32867535621.html?spm=a2g0s.9042311.0.0.3a3b4c4d5BJjid On Thu, Jul 8, 2021 at 7:37 AM Peter C.
