The PSL picomotor controls have been moved from the ISC Driver to the PSL Driver installed in the PSL-R2 Rack (alog 63613, alog 62830). The new DB25 cable is routed from behind the PSL field rack into the enclosure. The old controls cable was pulled out of the enclosure and will be reused for HAM1/JAC. Ryan Short is testing picomotors are operational through MEDM.

I moved the picomotor breakout box (D1101691-v1) from its previous location on top of the water pipes between the PSL table and the north wall of the enclosure (first picture) to underneath the center of the table (second picture) to accommodate the new DB25 cable coming from the west wall out to the PSL racks. New cable was routed through the floor cable manager and DB9 cables up to the table were coiled under the table to account for extra length. Cable routing from the breakout box up to and on the PSL table are unchanged.
I also tested all eight picomotors (four for the two mirrors for PMC steering, four for the two mirrors for RefCav steering) and all are working well and as expected.
