Sensor Docking Station
Frequency Sensor Wiring
There is only one opening for the frequency sensor docking
port. The F IN dock supports a 5 volt, 5000 Hertz pulse output
sensor.
The ground wire on a typical two-wire frequency sensor should
be connected to the same chassis ground that you used for
the power harness.
The diagram below illustrates the wiring configuration for a
two-wire frequency sensor.
1. Signal out from the sensor (5 volt, 5000 Hertz).
2. Ground (must go to the same chassis ground location as the Sensor
Docking Station chassis ground).
