The MRDI transmitter and portable receiver units are wireless devices developed by Southern Technologies to assist with wheel sensor alignment for the 2600-020 AEI Controller or the MRDI system. When used with the AEI Controller, the top four LEDs indicators (TO5-TO8) represent sensors TO1-TO4.
The Transmitter Unit activates when plugged into the AEI Controller. The Receiver Unit indicates the current state of each connected wheel sensor and provides a means to remotely monitor status changes while making precise adjustments at trackside.
The maximum working distance between the transmitter and receiver is approximately 150 feet (45.72 meters) line of sight. The AEI Controller provides power to the Transmitter Unit. The Receiver operates from a 9-volt battery.
