Hurraaaah!
We've got the damping of the suspension.
The Oplev loops has also worked!
The DAC channnel swapping was the last key!
DataViewer snapshot to show the damping against an artificial excitation was attached

Koji, Rana
The megatron DAC was temporaly connected to the suspension electronics for the DAC test. We went down to ETMY as we could not excite the mirror.
The DAC is putting correct voltages to the channels. However, the anti imaging filter test output does not show any signal.
This means something wrong is there in the DAC I/F box or the cables to the AI circuit. We will check those things tomorrow.
The ETMY was restored to the usual configuration.

It appears the front panel for the DAC board is mis-labeled. Channels 1-8 are in fact 9-16, and 9-16 are the ones labeled 1-8. We have put on new labels to reduce confusion in the future.
