The GV300W by Queclink (WCDMA / 3G variant of the GV300 family) is a professional-grade GPS tracker designed for Plaspy compatible deployments where reliable real-time tracking, robust telemetry and seamless fleet management are priorities. Built around a u-blox all-in-one GNSS receiver and a flexible set of vehicle I/O, the GV300W delivers precise positioning, extensive data acquisition and accessory integration for heavy trucks, cars and cold‑chain transport.
As a Plaspy compatible tracker, the GV300W can transmit GNSS, ignition and rich telemetry to your Plaspy platform over TCP, UDP or SMS. Its buffered logging and OTA control make it a strong choice for anti-theft protection, remote immobilizer implementations and mission-critical fleet operations that demand dependable reporting even in intermittent coverage areas.
Key Highlights
- Plaspy compatible real-time tracking via TCP, UDP or SMS for immediate location and alerting.
- High-precision GNSS with u-blox receiver (typical position accuracy <2.5 m CEP) for accurate route and asset monitoring.
- Comprehensive vehicle I/O: dedicated ignition positive trigger, multiple negative triggers, configurable and analog inputs for telemetry and fuel monitoring when paired with sensors or CAN readers.
- Anti-theft and immobilizer support by OTA control of digital outputs and a latched open-drain output for reliable vehicle disabling.
- Robust telematics features: geo-fencing, driving behavior, crash detection, tow and antenna disconnect alarms, plus data buffer for up to 10,000 messages.
- Compact, rugged form factor suitable for heavy trucks, cars and refrigerated transport (operating -30°C to +70°C).
- Accessory ecosystem support (CAN readers, temperature/humidity sensors, RS232 expanders) to extend telemetry and fuel monitoring capabilities.
How It Works with Plaspy
Integration with Plaspy is straightforward: configure the GV300W to send positional and telemetry packets over TCP, UDP or SMS to Plaspy endpoints. Plaspy can then parse GNSS, I/O and event messages to display real-time location, timeline events and aggregated telematics reports. The device’s internal buffering and scheduled reporting options ensure data continuity during temporary network loss.
- Real-time location and telemetry updates sent via TCP/UDP or SMS to Plaspy servers.
- Ignition detection through a dedicated positive trigger input and two negative trigger inputs for reliable engine status reporting.
- Fuel monitoring and additional analog telemetry using the configurable input (0–16 V) and analog input (0.3–16 V), or via CAN bus readers accessed through accessory support.
- Remote immobilizer implementation using OTA control of digital outputs and the latched open-drain output for secure anti-theft actions.
- External sensor integration (temperature, humidity) and RS232 devices via the 16‑pin Molex serial port, enabling cold‑chain and asset telemetry into Plaspy.
