Navtelekom - СИГНАЛ S-2550

The SIGNAL S-2550 is a cost-effective GLONASS vehicle tracker designed for reliable position reporting and basic vehicle telemetry in professional monitoring systems. Plaspy compatible by design, the S-2550 delivers essential data feeds—location, CAN bus diagnostics, and fuel sensor readings—so fleet managers and system integrators can add dependable real-time tracking without the complexity or cost of higher-end certified units.

The S-2550 is a streamlined derivative of the SIGNAL S-2551 series and targets mass-market fleet management and asset tracking where full regulatory compliance (for example, Russian Ministry of Transport Order No. 285) is not required. Although the model has been discontinued, operator documentation, an NTC Configurator utility (v.2.7.3) and a firmware archive remain available to support installation, configuration and maintenance of existing devices in the field.

Key Highlights

• Plaspy compatible: integrates position and telemetry into Plaspy for centralized real-time tracking and reporting.
• GLONASS-based GNSS positioning for reliable location data across covered regions.
• CAN bus integration via the CANLog interface for vehicle diagnostics and telemetry reading from the on-board network.
• Supports pulse, analog and digital (RS-232) fuel level sensors for accurate fuel monitoring and consumption analysis.
• Internal rechargeable battery provides autonomous operation and limited reporting during power loss.
• Streamlined, cost-effective option for fleet management and asset tracking where full regulatory certification is not required.
• Ongoing technical resources — operator’s manual, configurator utility and firmware archive — simplify field maintenance for deployed units.

How It Works with Plaspy

When paired with Plaspy, the SIGNAL S-2550 supplies continuous position and telemetry that Plaspy ingests, normalizes and presents in real time. Plaspy leverages these inputs to deliver live vehicle location, trip history, fuel monitoring dashboards and diagnostic alerts. The S-2550’s support for CANLog and multiple fuel sensor interfaces makes it particularly effective for telemetry use cases: Plaspy can correlate CAN-derived parameters with location and time to enable operational insights and prevent fuel loss.

• Real-time location and telemetry updates delivered to Plaspy for monitoring and reporting.
• Vehicle diagnostics read from the CAN bus (via CANLog) for engine and subsystem telemetry.
• Fuel monitoring via pulse, analog or digital (RS-232) sensors—Plaspy consumes calibrated sensor data for consumption and refill events.
• Autonomous reporting during power loss using the internal rechargeable battery—Plaspy receives position/alerts during short-term outages.
• Plaspy supports additional platform features such as ignition events, immobilizer control and Bluetooth sensors at the platform level; where those signals are available to the S-2550 or through auxiliary modules, Plaspy will consolidate them into a single telemetry view.

Technical Overview

Use Cases

• Fleet management — affordable real-time tracking and route monitoring for light commercial fleets where essential telemetry is required.
• Fuel monitoring and loss detection — integrate pulse/analog/RS-232 fuel sensors to track consumption, detect refuels and identify theft patterns.
• Diagnostic-based maintenance — read CAN bus telemetry for engine and subsystems to schedule preventive maintenance and reduce downtime.
• Rental and leased vehicle monitoring — position reporting and autonomous battery-backed alerts help protect assets and simplify returns.
• Assets with intermittent power — internal rechargeable battery enables limited reporting during power interruptions for higher asset visibility.

Why Choose This Tracker with Plaspy

The SIGNAL S-2550 is a practical, budget-conscious choice for organizations that need reliable real-time tracking and core telemetry without the premium features or certifications of high-end devices. Its GLONASS positioning and CANLog interface make it well-suited for fleet management scenarios where diagnostics and fuel monitoring are priorities. Plaspy receives the device’s location and telemetry streams and turns them into actionable dashboards, alerts and reports.

Although the S-2550 model has been discontinued, continued availability of documentation, a dedicated NTC Configurator utility (v.2.7.3) and a firmware archive means existing deployments can be configured, maintained and updated. For fleets that prioritize cost-efficiency while retaining essential telemetry and fuel monitoring features, pairing the SIGNAL S-2550 with Plaspy delivers dependable tracking, simplified integration and clear operational value.
