TIME LINE SCHEDULE

Put time line schedule here.

DETAILED CONSIDERATIONs

Cable Requirements

Do we have sufficient number of the cables ?
Let's doublecheck it.
Current Hardwares Lists

Notes about Binary Outputs

To obtain a voltage signal, a pull-up resister and a DC voltage are needed at the receiver stage because the signal is generated with a transistor.
An easy way to check this BO system is putting an LED on the receiver stage as described in the figure below. In this case if the signal is ON the LED lights up and vice versa.

test configuration
A datasheet for the BO card is here attachment:contec32BO.pdf

Reflective Memory Network

What is the temporary configuration ?
What is the final configuration ?

Simulated Plant for Green locking

Conceptual Design

- The control signals from the realtime control model (RCM) "GRN" goes to the suspension RCM "SUS, SCX and SCY"
Then the signal of coil actuation will drive a simulated suspension called "SUP and SPX/Y" instead of the real suspensions.
In the simulated plant each model mimics the response of the real interferometer, suspensions, PDs and so on.
After the signal goes through the simulated plant, the signal eventually come back to the RCMs as fake PD readouts.
