When adding the ETMX DAQ channels using the daqconfig gui (located in /opt/rtcds/caltech/c1/scripts/) on C1SCX.ini, we forgot to set the acquire flag to 1 from 0.
So the frame builder was receiving the data, but not recording it.
We have since then added ETMX and the C1SCX.ini file to Yuta's useful "activateDAQ.py" script in /opt/rtcds/caltech/c1/chans/daq/, so that it now sets the sensor and SUSPOS like channels to be acquired at 2k when run. You still need to restart the frame builder (telnet fb 8087 and then shutdown) for these changes to take effect.
The script now also properly handles files which already have had channels activated, but not acquired.
