We looked into the electronics for the new AS 90 MHz WFS, and found 2 mixups.  One we fixed, the other we ask Fil to fix tomorrow during maintenence. 

The cable for the binary I/O for AS B 90 was plugged into BIO 2, chassis 6.  However, according to E1300079 it belongs on BIO 4, chassis 4.  We made this swap, and the AS B 90 channels now look good, and respond to changes in the whitening state.

Half of the AS A 90 channels are still not good.  The problem seems to be that instead of the "normal" D1002559 whitening chassis, the "split variant" whitening chassis was installed.  These have the same DCC number, but the input panels and input adapter boards are totally different. For the normal version, all 8 channels are connected to the single input connector.  For the split variant (which is designed for use with the OMC DCPDs) 4 channels are on each of the 2 input connectors.  So, Since all 8 of our WFS signals are on one cable, 4 of those signals (I3, Q3, I4, Q4) are just going nowhere.  Anyhow, if Fil / Richard could put the normal variant of the whitening chassis in tomorrow during maintenence, we should be good to go with trying out our new AS90 centering loops.

Also, AS B Q1 signal looked dead, but after pushing the whitening cable in more, it is now fine.
