Navtelekom - SIGNAL S-4751

The SIGNAL S-4751 is a Plaspy compatible, high-functionality GLONASS vehicle GPS tracker engineered for modern fleet management and asset monitoring on 4G networks. Designed for demanding vehicle environments, the S-4751 combines external GLONASS/GPS and GSM antennas, a 4G modem with dual SIM redundancy, and robust power protection to keep vehicles and assets visible and secure in real time.

With on-board telemetry interfaces, Bluetooth 4.0 for local configuration and peripheral sensors, and local logging to an SD card, the SIGNAL S-4751 is ideal for operators who need reliable real-time tracking, anti-theft controls, remote diagnostics, and flexible integration with Plaspy and third-party telematics platforms. Firmware management tools and a DRC remote management system simplify large-scale deployments and ongoing maintenance.

Key Highlights

• Plaspy compatible GPS tracker built for 4G networks — dependable real-time tracking for fleets and assets.
• Dual-SIM 4G modem and external GSM/GLONASS antennas for improved connectivity and location accuracy.
• Robust vehicle-grade power protection (up to 200 V) and an 800 mAh Li‑Po backup battery for continuous operation during power loss.
• Extensive I/O and industry interfaces (6 universal inputs, 4 programmable outputs, RS-232, RS-485, CAN, 1-Wire) to support telemetry, ignition monitoring, and control functions including immobilizer use.
• SD card logging up to 32 GB for offline data retention and cargo/security event history.
• Bluetooth 4.0 for quick local configuration and connection to Bluetooth sensors and beacons.
• MODBUS support and standard serial/CAN ports for fast integration with vehicle electronics and third-party telematics systems.

How It Works with Plaspy

The SIGNAL S-4751 streams GNSS position data and vehicle telemetry to Plaspy for immediate visualization, geofencing, alerting, and historical reporting. Plaspy-compatible integration leverages the device’s reliable 4G connectivity and local logging to maintain continuous situational awareness even when cellular coverage fluctuates.

• Real-time location and telemetry updates: GNSS (GLONASS/GPS) position data is sent over the 4G modem to Plaspy for live tracking and route replay.
• Ignition and event monitoring: universal digital/analog inputs can report ignition status and other vehicle alarms to Plaspy.
• Fuel monitoring and analog telemetry: analog-capable inputs support fuel level sensors and other analog telemetry for fleet efficiency reporting.
• Remote immobilizer/control: the 4 programmable outputs can be configured for remote immobilizer or other control actions via Plaspy commands when allowed by local law and safety policies.
• Bluetooth sensors and local peripherals: Bluetooth 4.0 enables local sensor pairing and configuration; sensor data can be forwarded to Plaspy when supported by your integration.
• Offline resilience: SD card logging up to 32 GB provides a local backup of trips and events for later upload to Plaspy if real-time connectivity is interrupted.

Technical Overview

Use Cases

• Fleet management: live GPS tracker integration with Plaspy for route monitoring, driver behavior, and dispatch coordination.
• Anti-theft and immobilization: asset security with remote control outputs and location tracking to reduce vehicle theft risk.
• Cargo security and event logging: SD card logging and real-time alerts for door, alarm, or unexpected route deviations.
• Remote diagnostics and telemetry: CAN, RS-232/485 and MODBUS allow vehicle health, fuel monitoring, and sensor telemetry to be reported into Plaspy.
• Bluetooth sensor deployments: temperature, presence, or proximity sensors paired via Bluetooth 4.0 for sensitive cargo monitoring or short-range detection.

Why Choose This Tracker with Plaspy

The SIGNAL S-4751 delivers a balanced mix of connectivity, resilience, and integration flexibility that makes it a strong choice for organizations deploying Plaspy-compatible GPS tracker solutions. Dual-SIM 4G connectivity and external antennas help ensure reliable real-time tracking, while the internal Li‑Po battery and SD logging preserve data across power or network interruptions. Extensive inputs, outputs, and serial/CAN interfaces enable advanced telemetry — from fuel monitoring and ignition sensing to remote immobilizer actions — and the device’s MODBUS and standard ports simplify integration with vehicle electronics and third-party systems. Combined with DRC remote management and the NTC Configurator for firmware and configuration control, the S-4751 offers a scalable, maintainable platform for fleet management, anti-theft protection, and comprehensive telemetry reporting within Plaspy deployments.
