Per E1600247 and ECR1600246, the following electronics were modified or relocated:

HAM6 shutter controller S1203609 was relocated from ISCT6 table (top) to rack ISC-R5, slot U2/3.

Changed R23 from 26.7K ohms to 12.4Kohms in the QPD transimpedance amplifier chassis S1301506. This was to increase the maximum threshold for the AS port trigger PD as seen by the shutter controller. See alog entry.

Cabling to ISCT table has been reconnected. The high voltage supplies for both the fast shutter and PZT are now power on.
