Theory of Operation
The FM-1600 moves the two armature fibers that are physically connected together. They stop pre-
cisely in front of fibers 0 through 7. The microprocessor receives position and command data from the
keyboard controls as well as the Rs-232 port. The appropriate information is displayed on the unit’s
LED display or sent out over the Rs-232 port. There are no electronic adjustments. Also there are no
user available mechanical adjustments inside.
