To allow a regular signal to be acquired by the last channel of the first ADC in each IO Chassis, we (Rolf and I) have made a code change to the IOPs such that the DuoTone signal from the TDS card is no longer routed to that channel.
These changes have been made to the following frontends: h2susb478; h2susb78; h2susauxb478. Team SEI will make the change on their next code change.
Note that the DuoTone diagnostic field on the GDS_TP.adl medm screens are now showing random numbers and should not be used (This is the left field in the DT/IRIG line, showing a value of -237 on the attachement)
I hope that this is not a permanent solution. For ISC and suspension, not monitoring the timing at all sounds like an insanity.
For completeness, here are the two lines which were changed in src/include/drv/cdsHardware.h to remove the duotone:
svn di src/include/drv/cdsHardware.h
