The GV56RS has more features than our GV56 model and utilizes wired accessories based on the RS485 serial port. This product supports up to ten sensors, including fuel and load, and is designed for trucks with more than one tank containing liquids. The GV56RS is similar to the GV56 and is ideal for use in light vehicle tracking applications such as usage-based insurance, car rental, stolen vehicle recovery, logistics, and much more. The GV56RS optimizes the available I/Os allowing fuel cut, ignition detections, and a single analog sensor in addition to driver ID identification over 1-wire or BLE. Supported accessories include a range of BLE-based fuel and weight monitoring solutions offered by our partners.
