Since the EX system was added to the DAQ we have been seeing two problems in the frame:

• all fast channels have been incorrectly marked with dataValid=1
• some DUST slow channels have been corrupted

Alex found that there is a limit on the number of DCUs acquired by the DAQ, the limit is 85. We had 94 DCUs in the DAQ.

We removed 16 DCUs from the DAQ this afternoon, and both problems have gone away (Patrick verified all DUST channels have good data).

Alex will test a fix to allow the full complement of DCUs in the DAQ next week. For now the systems listed below are out of the DAQ:

h1iopsusauxh56, h1susauxh56

h1iopsusquadtst, h1susquadtst

h1iopsusbstst, h1susbstst

h1iopseitst, h1isitst

h1iopsusex, h1iopseiex, h1iopiscex, h1iopsusauxex

h1iopsusey, h1iopseiey, h1iopiscey, h1iopsusuxey
