h1susex DAC and Timing Card Temperatures
RCG5.3.0 reads out the FPGA chip temperatures for both the Timing Card and the new LIGO 28AO32 DAC card. These are available as EPICS channels and can be trended in ndscope.
The attached image shows the past 24 hour trend, and where you can find these temperatures on the RCG MEDMs.

Note that because of heating concerns, Marc installed a third cooling fan on the h1susex IO Chassis utilizing the square hole in the front of the chassis which used to house the Columbia timing stack. The new DAC is centered on the 3rd Adnaco backplane, squarely in front of this fan.
