- Page 4 Mirror Controller: The mirror controller electronics are housed in a remote enclosure connected to the FSM via a 6 foot cable. Mirror commands are input to the controller through a 25 socket D sub-miniature connector. The commands are differential signals representing the x and y mirror positions, scaled to the +/- 10 volt range.

The mirror can be driven while this card is pulled forward, allowing the user to optimize the PID values for a given step requirement while monitoring the position and error signals on a scope.
