GV355CEU-All-purpose LTE Cat 1 telematics terminal with cAN and dlgital tachograph data reading
The device uses a u-blox all-in-one GNSS receiver supporting GPS, Glonass, Galileo, and Beidou constellations. It offers a cold start sensitivity of -148 dBm, hot start sensitivity of -160 dBm, and tracking sensitivity of -167 dBm. The position accuracy is less than 2 meters, with a cold start time of 24 seconds on average and a hot start time of 1 second on average.
The device operates on LTE-FDD bands B1/B2/B3/B4/B5/B7/B8/B20/B28, with a maximum data transmission rate of 10Mbps for download and 5Mbps for upload.
It supports frequencies of 850/900/1800/1900 MHz, with EDGE data transmission rates of up to 236.8Kbps for both download and upload, and GPRS rates of up to 85.6Kbps.
The device supports TCP, UDP, and SMS protocols for data transmission.
Dimensions are 94(L) × 58.5(W) × 21(H)mm, with a weight of 92g. It includes a Li-Polymer backup battery of 250 mAh and operates at a voltage range of 8V to 32V DC. The operating temperature range is -30°C to +70°C, with a storage temperature range of -40°C to +80°C. BLE 5.2 protocol is supported.
The device includes various inputs and outputs: one positive trigger digital input for ignition detection, three negative trigger inputs, two analog inputs, one digital output, and one latched digital output. It also features a configurable I/O, RS232 and RS485 serial ports, CAN interfaces for heavy and light vehicles, a K-Line for tachograph data, and internal antennas for cellular, GNSS, and BLE. LED indicators show network, GNSS, power, and CAN/J1708/tachograph status. A mini USB interface is available for configuration, upgrade, and debugging, and a 1-wire interface supports temperature sensors and iButton driver ID.
The device includes scheduled reporting, geo-fence alarms, low power alarms, power-on reports, tow alarms, driving behavior monitoring, crash detection, special alarms, remote control, and remote tachograph downloading capabilities.
