Complete the permanent CRS electronics installation in anticipation of IR1
We finished step 3 of this WP, pulling two of the 140ft DB25 cables from TCS-R2 to the SUS-C1 in the CER.
We started by laying out the cables, wiping them down, and testing them to for continuity. As expected pin 13 is connected to shield on one end of the cables, keep this in mind for future, these are reused cables, so the shield connected end may not be the end of choice. There was plenty of extra cable length left, this was pulled to the TCS rack side. The CER end of the cable has enough slack to be moved over to Beckhoff if this is required in the future.
