I was looking at the ALS-C_REFL_DC_BIAS output at the floor. The signal appeared on output 3 instead of 1 of the D-sub breakout panel. This was traced to a wiring error in the lsc model. Now corrected in the model, but not recompiled yet. This output has been connected to the second input of the common mode board and is operational. When the lsc model gets recompiled, the signal needs to be reconnected to output 1. The corner ALS overview screen has been updated to show the new filter modules.
