IP_POS is back.
I reconnected the cable to an interface card : D030238-A which has been labeled as "IP POS".
The card currently resides on the third crate rack from the top at the very right side in 1Y2. Also a rear side connection was modified a little bit.
I will clean up some cables because I tried some cables to see which was which.
Hopefully I will make a simple wiring diagram such that we will never forget the connections.
A cable for IP_POS has been disconnected at the LSC rack, 1Y2. Due to it currently no IP_POS signal shows up on the digital side.
I will check how it used to be and reconnect it.
I found the disconnected cable, but I do not see the interface board at the LSC rack
