Reprogrammed the MSR IRIG-B at 12:45 PDT with Rev. 113 code (provides compatibility with the display to be used in the Control Room). Last week, Jim and I used the test stand to confirm that the flywheels in the IRIG-B PCI cards could keep stable time over a few minute interruption in the IRIG-B signal. Reprogramming took 38 seconds; the whole process of reprogramming, rebooting, resyncing, and confirming the time zone/leap seconds took 102 seconds. I had to add the leap second scheduled for later today.

MEDM screens for MSR IRIG-B are nominal. The rack-mount LED display no longer works, since Rev. 113 changes the display signal to be compatible with the display model to be used in the Control Room. Work permit 5317.
