Notes and Changes:

This version (-F/-v4) is a consequence of ECR E1200934. The changes are explained in E1200907. This board has the following four types:
1) LL type: Arm Length Stabilization (ALS), Laser Locking
2) ALS type: Arm Length Stabilization (ALS), Cavity Locking
3) MC type: Input Mode Cleaner (IMC) Cavity Locking
4) CM type: Interferometer Common Mode
The component values for each type are given in E1200907. (Note that some, but not all, component value changes for each type are given in the D040180-F/-v4 schematic).
