The sensor module allows up to 8 transmission sensors to be monitored. 8 BI-color LED’s are used and are:

Red = positive voltage

Green = ground

Orange = pulsing

Off = floating

Need more accuracy? Each sensor has a test point that you can plug in a scope, multimeter, or frequency meter. Neatly and conveniently. Oh by the way, the sensor module can be changed so that as needs change we can provide other modules.
