QRT02
Telemetry transmitter is designed for installation in passenger cars like also in truck and vans. QRT02 transmits data (position GPS, many parameters read from CAN-Bus/CAN-FMS of vehicle and from additionally inputs) to the fleet management system.
Device have GPS positioning module, GSM transmission modem, interface to CAN-Bus of vehicle, digital inputs (include counter), analogue inputs, inputs for digital fuel probes and 1-wire interface for measure of temperature or identyfication. For continuous operation of device inside is build-in battery. When is required longer time of operation without powering then is possible to connect external, more capacity battery.
