End Of Train Telemeters : Basic EOT Rear Unit.

Basic EOT Rear Unit

The rear unit consists of a microprocessor, radio modem, radio, pressure transducer, side mounting style clamp and an integral antenna. The Pressure transducer can measure both air brake pressure and vacuum. If the air-pressure changes more than 10Kpa or the vacuum changes more than 5 Kpa, a message is immediately sent to the cab unit every time it changes. If the pressure or vacuum is stable, the cab unit's display is updated every 60 seconds. The cab and rear units operate as a matched pair. Each of the pair units is coded with an ID number. A cab unit will only decode a message from his corresponding rear unit.

All the Telemeters operate on a single frequency. The rear unit can also be fitted with a second short range digital receiver. This receiver can receive messages from track-side equipment and has a range of 50 to 100 meters. This allows for interfacing to low cost track side equipment like dragging equipment detectors and section-clear signals.

The InTeleTrack Telemeter system is designed to be a simple, rugged and reliable system. The clamp on the rear unit can fit on all the known types of buffers in Southern Africa and can be changed to fit other types of buffers.
Maintenance is done by changing modules. All components are readily available from local suppliers.
