<<Does anyone know how the sensor transmits its info to the VMS computer?
If
one knows how far it's off, I bet it's not impossible to create a circuit to

"recalibrate" the signal.>>

It is a square wave with about a 10% duty cycle. The DPU counts the pulses
over time (frequency). While possible to make a frequency shifter, it is
much easier to burn an EPROM with the correct coefficient.
