Overview:
The galvo driver box contains power supplies for the three galvo drivers. In addition the box contains a circuit that couples the two Y galvos through a Gain and provides an offset to Y1.
The galvos need to be operated in differential mode. This is determined by jumper settings on the galvo drivers boards. They are usually shipped configured for ‘common mode, non-inverting’ To switch to differential mode, only jumper 1-3 need to be connected. This usually means that jumper 4-6 needs to be disconnected. (see MicroMax Series 671 Cambridge Technology manual).

Zero the inputs through the BNC cables - in other words, short the X and Y inputs.
The LEDs on each driver board should turn green after the power is turned on.
