[J.Kissel, E.Goetz, T.Mistry]
During the Tuesday maintenance time, between the times 09:30 PDT to 11:15 PDT, we went to the X End to inspect the cables, apply relevant labels and remove unnecessary NCAL parts from the end station. The NCAL remain unplugged and fully powered off apart from the NCAL PC thus, there is no way a signal can be passed from the PC to the NCAL (see LHO alog 53689). This is because the NCAL PC is located in the same racks as the power supplied and other computer systems and we are confident that the NCAL PC contributions to noise (i.e. emf, acoustic, etc) is minimal or negligible compared to the other systems in the racks.
An updated cartoon of the as-installed wiring diagram can be found at D1900015-v5 and a PDF attached to this alog. Hopefully this diagram will aid in understanding the electronic configuration of the NCAL system. A more detailed system (pin-to-pin) diagram can be found at D1900499.
