The ei simply picks up a signal from the mag, at least the rpm-1 does.
The E.I. standard RPM module takes the mag pulse and converts it to a signal that can be sent to the UBG-16 via a thermocouple input chanel.
My question is, does the RPM-1 send a similar signal when it is sending info to the MGL data logger? If so, can I just send that signal to the UGB-16 instead.
The RMP-1 gets it's reference from a Hall Effect sensor.
