Following IO Chassis Timing Card Firmware Upgrades all Duotone times are now sub 1 microsecond

The completion of the Timing Card Firmware upgrade has brought all the IOP Duotone timings to below 1uS (were in the 7uS region).

Duotone times are now either around 0.0uS or around +0.5uS due to a board manufacture variation.

CDS Overview Changes.

Beckhoff Slow Controls DEV1:

Following the reactivation of the LVEA chamber illuminators yesterday the DEV1 terminal count went from its degraded state of 21 to the full complement of 23. This is because during O4 the illumintor controls were found to be noisy and were powered down. To show this degraded state the CDS Overview used a slightly darker green for a terminal count of 21.

So that we don't forget to address this noise issue and/or power down the illuminator controls before IR1 starts, I'm displaying DEV1 in a dark yellow colour when all the terminals are present as a reminder.

Model RCG version and IOP Timing Card Version:

Now all models are running with RCG5.5.2 and all timing cards have the latest Firmware version I've green'ed up these tags on the overview.

The RCG tag will turn BLUE if not 5.5.2. The IOP tag will turn BLUE if the Duotone is out-of-bounds.

Timing card version is now:
