The front end timing was not working properly for 2 of the IO chassis. They were not being synced to the 1 PPS signal.
This prevented the use of RFM for communication between front ends because time stamps on the transmitted data did not match the cycle on the receiving machine.
We took one of the incorrectly working chassis over to Downs. Rolf said he would take a look at it tomorrow morning.
Joe will be going over tomorrow morning to talk with Rolf and see what needs to be done to fix it.
