End-Y ISC cabling 95% complete (Dan Rodney Fil Alberto)
Over the past few days we've cabled up the ALS table and the field rack at EY.  Using the diagrams in D1100670-v6, things are very close to finished.

All but four of the cables on the ALS table are connected (on the table-end).  The four cables missing are for the CCD camera (power & video out), the EOM RF input, and the fiber input from the "PSL".

The following boards are missing from the field rack:
VCO
iLIGO LSC RFPD Interface
Uniblitz shutter controller

All of the cables for the existing boards in the field rack have been landed.  The missing cables are for the RF connections from the oscillators in the high-bay to the RF patch panel and a few other things.

On the CDS high-bay side, none of the slow controls cables have been connected to the Beckhoff EtherCat chassis; I would prefer not to plug things in until we have looked at software models, etc to make sure we're not driving picomotors, PZTs, and so on with garbage signals.  But soon, soon...

Some notes:

 - in the ASC Demod Concentrator (D1100696), there are two controls outputs ('A' and 'B' on the rear panel), but in the cabling diagram there is only one cable (Cable 78).  I think there should be two since we've got two WFS; Cable 78 is currently connected to the 'A' slot.

 - For the picomotor driver, we've connected CAB_H2:ISC_WBSC6-64 to the readbacks, and CAB_H2:ISC_WBSC6-13 to the controls.  Note that cable 13 isn't in the final cable layout, but it had already been pulled, so we used it anyway.  Should have been CAB_H2:ISC_WBSC6-65.

 - All of the cables were too long - which is better than the alternative!  We had about 12 ft of excess on the ALS-table-to-field-rack connections, and many many feet of excess on the field-rack-to-high-bay connections.
