How does the E-VDT work?

The Engine Vehicle Diagnostic Transmitter (E-VDT) wirelessly communicates data to a Chameleon Modem providing real time fleet management access to operating parameters such as speed, RPM, idle time, gas mileage, and odometer readings. The E-VDT connects directly to the OBD port of light and medium duty vehicles from 1996 or later. It can also connect to a J1939 interface cable for use with heavy duty vehicles.
