The S-4651 is listed by Navtelekom as an archived model, and while documentation and firmware history remain available, verify specific functions against the device documentation and firmware notes for your unit.

Feature Overview​

The СИГНАЛ S-4651 is a vehicle grade GLONASS and GPS tracking terminal built for continuous fleet monitoring across 2G 3G and 4G LTE networks. It is designed to minimize data loss, provide flexible I O and industrial interfaces for telemetry, and support local logging and remote maintenance tasks.

  • Multi network cellular connectivity with dual SIM failover to maintain continuous reporting in mixed coverage areas
  • External GLONASS GPS and GSM antenna support for improved reception in vehicle installations
  • Rich I O set and configurable outputs for monitoring ignition, doors and other vehicle inputs
  • Industrial interfaces and protocol support for third party telemetry and diagnostics
  • Local data logging on microSD and an internal backup battery to preserve position and events during power interruptions

Core Features of Navtelekom - СИГНАЛ S-4651 (4G)​

  • GLONASS and GPS positioning with external antenna support for reliable satellite reception
  • Multi network cellular modem supporting 2G 3G and 4G LTE with dual SIM failover for improved uptime
  • Vehicle grade power protection and integrated Li Po backup battery to preserve data during power loss
  • Universal I O set including six digital and analog inputs and four configurable control outputs for sensors ignition and immobilizer control
  • Industrial communications including RS 232 RS 485 CAN bus and 1 Wire plus MODBUS support for external telemetry devices
  • Local data logging on microSD card up to 32 GB for historical playback and recovering missed reports
  • Bluetooth 4.0 for local configuration and accessory pairing
  • Remote firmware management capability for lifecycle updates and maintenance

How These Features Work with Plaspy​

Plaspy ingests positioning and event data from compatible trackers like the S-4651 so fleet managers can view live location, receive alerts, and review historical telemetry in a single platform. In many deployments Plaspy automatically detects the tracker protocol and presents captured data in the Plaspy dashboard without manual protocol selection.

  • Real time GNSS coordinates and position updates are visible in Plaspy for live monitoring and map playback
  • Digital and analog input events feed alerts and status indicators such as ignition and door events into Plaspy
  • CAN bus RS 485 and MODBUS telemetry can be forwarded to Plaspy for equipment diagnostics and reporting when configured
  • Local microSD logs enable reliable historical data recovery and playback inside Plaspy when connectivity is restored
  • Configurable outputs including immobilizer or actuator control can be triggered by Plaspy rules or remote commands where supported

Typical Use Cases​

  • Fleet location tracking and route playback for dispatch and operational oversight
  • Remote immobilization and anti theft workflows using configurable outputs
  • Door and alarm monitoring for security and compliance reporting
  • Fuel level and other analog sensor monitoring integrated into Plaspy reports
  • Cargo condition or proximity workflows using Bluetooth accessories
  • Industrial telemetry collection from vehicle mounted equipment via RS 485 CAN or MODBUS

Feature Availability Notes​

  • The S-4651 is listed as discontinued or archived by the manufacturer; documentation and firmware history remain available but feature sets may differ between firmware builds
  • Hardware revisions and installation wiring can affect which I O and interfaces are present or enabled on a specific unit
  • Regional cellular variants and carrier provisioning may change supported network bands and connectivity behavior
  • Plaspy will attempt automatic protocol detection but correct server and connection settings are required for reliable reporting
  • Confirm remote control capabilities and exact I O mapping in the official Navtelekom configuration documents for your unit

Why Use Plaspy with These Features​

Using the Navtelekom СИГНАЛ S-4651 (4G) with Plaspy gives operations teams a path to combine robust vehicle grade tracking hardware with a centralized fleet management platform. The tracker’s multi network cellular design dual SIM failover and local logging reduce blind spots, while its I O and industrial interfaces let Plaspy capture both discrete events and richer telemetry for reporting and alerts.
