H1 ISI ETMX Front-end Model Bug Fixed -- End X T240 Now in Frames
J. Kissel, C. Ramet, S. Biscans, B. Lantz

While grabbing data for the windy day today, I found that the temporary T240 that has installed at the X end station (see LHO aLOG 9758) was not being read out by the channels H1:ISI-GND_ETMX_{X,Y,Z}_DQ, and therefore not stored in the frames as expected. I found that the bug was in the ISI's front-end model where the channels on which the T240 were coming in were piped into the spigots for the "A" STS right off of the ADC, where it should be piped into "B." Check out D1400077 for more details and detailed redlines to both the analog wiring diagram and Simulink front-end wiring diagram. Finally, I've filled in the STS2CART matrix such that the T240 is now properly piped into the ground sensor correction path.
