Aidan had some more acromag cards in the TCS lab, he has given them to me.  I have one more XT1541 and one more XT1221

At this stage the plan is to wire them up to interface with the TTFFS interface boxes so gains and lock engage can be computer controlled.  This can use a simple EPICS interface but also allows for scripted control of the lock engage.  Right now when the FFS control box is set to remote mode it MUST be provided with voltages corresponding to gains of each of the servo stages.  Without this there is no tunablity of the control loop gains from the front panel.  Eventually, when the mode cleaners are implemented, the reference cavities will need to be locked conditional on the mode cleaner state.   Having a scriptable engage will be useful for keeping all of these locks going.  

Also, there are a bunch of other bits of the experiment that we may want to temperature control: EOMs, modecleaners, etc.  Extra channels for temperature readout and actuation should be handy.
