To summarize the ongoing issues from yesterday:

• we determined that the cables (DCPD and PZT) attached to each OMC are mixed up
• one cable has incorrect wiring, because the ground pins are not where they should be (pin 2 and 5 are ground instead of 6 and 9)
• we're not sure if the polarity is correct on the diode

Keita and I have decided that swapping cables can possibly be done without removing the DCPDs. We're going to determine OMC A and OMC B based off of the PZT cable, and then swap the DCPD cables. We're waiting to hear the final verdict on the diode polarity to do pin adjustments and cable swapping.

In the meantime, Oli and I installed OMCB on the suspension and bolted it down using the OMC alignment template. We have placed the butterdishes over OMCA and B, but we haven't secured them yet with viton clamps while we continue to do work on the OMCs. The cables are only loosely clamped.

Next, Oli and I worked first contacting the remaining optics for BHSS- two HRs and one 50/50 splitter. The HRs were finished today, installed in their mounts, and placed randomly on the platform. The 50/50 splitter is still being FCed and should be ready in the morning. Once that optic is installed, we will proceed with the alignment of the OMCs and optics.

One vertical clamp is still missing from OMCB, but we should be able to install it once the helicoils and such arrive.
