WARNING: All analog signals between DM-1 and PTV Chassis are differential outputs.
All signals except "data communications" have matching "reference" output. To measure,
hook scope probe to convenient ground and measure signal. The "reference" for any
given signal is the same but 180 degrees out of phase. Always consult the schematic for
the actual pin number of the desired signal. Connecting the ground clip of a grounded
scope to the REF line will cause damage to components.
