The top name of the channels has been changed from GCV to ALS      

=> Although the model name itself is still C1GCV to keep the current relations between other computers.

I and Q signals on each sensor.

LOCKIN modules to detect the sign of the error signals by shaking suspensions.

Offset adjusters, which are combination of a controllable epics value and a low pass filter, to allow a smooth length scan.

Input matrix. This branches the input signal to the DOFs as well as the LOCKIN modules.

Output matrix to allow some combination of actuation (e.g. DARM, CARM, MCL, etc.,)

Output switch to enable/disable any feedbacks to the suspensions

Output filters before the suspensions. These filters will be usually flat, but enable us to inject some signals and enable some limiters.

 

Here is the latest medm screen for the modified realtime controller.

It gives you the idea of how the latest model works.
