Eventually the DRMI was locked.
I was struggling to find a good signal port for SRC over the weekend and finally found AS55_I worked somehow. I used :
REFL11_I --> PRC
AS55_Q --> MICH
AS55_I --> SRC
A configuration script was prepared such that someone can try this configuration by clicking a button on the C1IFO_CONFIGURE.adl screen.
I don't think this signal extraction scheme is the best, but now we can find better signal ports by shaking each DOF and looking at each signal port.
More details will be reported in the morning.
I will try with POY55 that Koji prepared today.
