BE VERY CAREFUL WHEN DOING ANY WIRING. IMPROPER
WIRING WILL DAMAGE THE MOTOR SIGNAL GENERATOR.
Two pins are directly connected to ground and +5V from the internal
power supply. These are provided for convenience as a source for the
optical ground and o5V if there is no external power source
available. Using the internal supply to power the optical isolators will
negate most of the isolation provided by the optical isolators. To use the
internal supply, directly connect DB-25 pin 24 to 25 and pin 22 to 23.
The motor signal lines as seen from the back of the box are arranged as
follows:
