Navtelekom - SIGNAL S-4751 Features

This page provides a public, feature focused description of the Navtelekom SIGNAL S-4751 and how its capabilities are used with Plaspy. It is intended to help fleet managers, integrators, and technical evaluators understand the practical functions the device provides when reporting into Plaspy for tracking, telemetry, and operational oversight.

Exact feature availability and behavior can vary by firmware version, hardware revision, region, installation type, and the manufacturer implementation. For device specific technical limits, supported bands, firmware changes, and the latest configuration tools consult the official Navtelekom documentation.

Feature Overview​

The SIGNAL S-4751 is a GLONASS enabled vehicle tracker designed for demanding fleet and asset monitoring applications over 4G networks. It combines resilient connectivity, local logging, and expanded I O and serial interfaces so vehicles and assets remain visible, controllable, and diagnosable in real time.

  • Real time GNSS tracking using GLONASS and GPS with an external antenna for improved reception.
  • 4G modem with dual SIM redundancy to maintain cellular connectivity across networks.
  • Vehicle grade power protection and internal backup battery to sustain operation through power disturbances.
  • Local SD card logging for offline data retention and later upload to Plaspy.
  • Bluetooth 4.0 for local configuration and short range sensor or peripheral connections.

Core Features of Navtelekom - SIGNAL S-4751​

  • GLONASS GPS positioning with support for an external GNSS antenna to improve location reliability.
  • 4G cellular modem with dual SIM capability to reduce downtime from single network outages.
  • Robust vehicle power protection up to 200 V and an internal Li Po backup battery for continuity.
  • Local storage via SD card support up to 32 GB for trip and event logging.
  • Multiple telemetry interfaces including universal digital and analog inputs and programmable outputs for event reporting and basic control.
  • Serial and vehicle bus interfaces such as RS 232, RS 485, and CAN plus 1 Wire for peripheral devices and sensors.
  • Bluetooth 4.0 for local setup, configuration, and supported sensor pairing.
  • Protocol and integration support including MODBUS and compatibility with remote management tools such as DRC and the NTC Configurator.

How These Features Work with Plaspy​

Plaspy receives location and telemetry from the SIGNAL S-4751 and presents that data for live tracking, alerts, historical reporting, and operational workflows. The device is designed to provide continuous situational awareness and to preserve event histories for later analysis when connectivity is intermittent.

  • Real time location reporting visualized on Plaspy maps and route replay tools.
  • Telemetry and event inputs reported as status indicators and events inside Plaspy for monitoring ignition, door, or other digital signals.
  • Local SD card logs can be uploaded to Plaspy to recover trip history when real time reporting was interrupted.
  • Programmable outputs allow remote control actions to be initiated from Plaspy where device configuration and local regulations permit.
  • Serial and CAN data made available to Plaspy integrations for vehicle diagnostics and sensor telemetry when configured.
  • Bluetooth based local configuration simplifies on site setup and can support forwarding supported peripheral data into Plaspy.

Typical Use Cases​

  • Fleet route tracking and dispatch coordination with live location and historical trip analysis.
  • Anti theft monitoring with location recovery and remote output control where supported by installation and policies.
  • Cargo security and event recording with SD card backups for missed connectivity periods.
  • Remote diagnostics and vehicle telemetry collection using serial and CAN interfaces for maintenance workflows.
  • Deployments requiring resilient cellular connectivity using dual SIM redundancy.
  • Short range sensor or beacon integrations using Bluetooth for asset proximity or door monitoring.

Feature Availability Notes​

  • Firmware and software updates can change feature behavior and available configuration options; verify firmware level before deployment.
  • Hardware revisions and regional variants may affect supported cellular bands and the exact set of interfaces provided.
  • Some control actions such as remote immobilizer commands depend on local regulations and safe installation practices.
  • Bluetooth peripheral support and specific sensor compatibility depend on local setup and firmware support.
  • For detailed electrical limits, supported bands, and wiring practices consult the manufacturer documentation and installation guides.

Why Use Plaspy with These Features​

Using the SIGNAL S-4751 with Plaspy gives organizations a combined solution for continuous location awareness and flexible telemetry reporting. Plaspy consolidates GNSS positions, input and output events, and logged trips into dashboards and reports that support operational decisions, security workflows, and maintenance planning.
