Ansel, Jim, Dave:
We upgraded the final timing systems. In the staging building we upgraded the Fanout, IRIG-B and IO Chassis units. We turned these systems off after we were done to save power.
The DTS fanout was the first to be upgraded, so it had the 118 version of the code. All the other fanouts were upgraded to 121 recently, and we installed this version in the DTS. Now the master is not complaining about a firmware error on port 8.
