Navtelekom - SIGNAL S-2551 Configuration

This page covers the public configuration context for using the Navtelekom SIGNAL S-2551 tracker with Plaspy. It summarizes the practical server settings and the typical steps integrators use to point the tracker to Plaspy, explains what to check before integration, and highlights how Plaspy receives device data. The content below uses publicly available Plaspy connection parameters and the SIGNAL S-2551 product description as the factual basis.

Plaspy uses shared server settings across supported devices and automatically detects the tracker protocol, while the exact manufacturer side setup steps can vary by firmware version, hardware revision, installation type, and vendor configuration tools. Use this guide to prepare the device for Plaspy ingestion and then follow the SIGNAL S-2551 manufacturer documentation and configuration tools for device specific steps.

Configuration Overview​

The goal of configuration is to prepare the SIGNAL S-2551 to send GNSS positions and telemetry to Plaspy reliably using the platform's shared endpoint and port. This includes updating server fields, selecting the appropriate transport, confirming cellular connectivity, and validating that Plaspy is receiving data.

  • Point the device server settings to Plaspy using d.plaspy.com or the equivalent IP address.
  • Configure the device to use port 8888 which Plaspy uses for all supported devices.
  • Choose UDP or TCP transport if the tracker requires a transport selection.
  • Ensure dual SIM and GPRS settings are functional for cellular data transmission.
  • Save and apply settings with the SIGNAL S-2551 configurator or SMS commands and verify the device appears in Plaspy.

Plaspy Server Settings​

  • Server domain d.plaspy.com
  • Server IP 54.85.159.138
  • Port 8888
  • Transport support for UDP or TCP
  • Plaspy automatically detects the tracker protocol and uses the same port for all supported devices

Typical Requirements Before Setup​

  • Access to the SIGNAL S-2551 official configuration method such as the NTC Configurator or manufacturer SMS commands
  • A powered and installed device with cellular connectivity and at least one active SIM for GPRS data
  • Knowledge of the device IMEI and any administrator credentials required by the manufacturer tool
  • Confirmation that the device firmware supports EGTS, FLEX, or the protocol variants used by Plaspy
  • A test vehicle or bench setup to validate GNSS reception and telemetry reporting
  • Optional microSD or USB access if local logging or offline configuration is needed

How This Tracker Connects to Plaspy​

When configured for Plaspy, the SIGNAL S-2551 transmits GNSS position and telemetry data over cellular data channels to the platform endpoint on the shared Plaspy port. Plaspy ingests the data, maps the device to the customer account, and presents real time location, I O state, and telemetry for dashboards and alerts.

  • The device reports to the shared Plaspy endpoint d.plaspy.com or 54.85.159.138 on port 8888
  • Transport is selectable as UDP or TCP where required and Plaspy accepts either
  • Plaspy automatically detects the device protocol so the tracker can use EGTS, FLEX, or a supported custom protocol
  • Data sent includes GNSS position plus configured telemetry channels such as digital inputs, analog sensors, and CAN data when enabled
  • Plaspy provides visibility for real time updates, historical replay, and rule based alerts

Common Configuration Workflow​

  1. Access the official SIGNAL S-2551 configuration method or software provided by Navtelekom such as the USB configurator or manufacturer web tools.
  2. In the server settings enter d.plaspy.com or 54.85.159.138 as the primary server address.
  3. Set the server port to 8888 to match the Plaspy shared port used for all devices.
  4. If the device requires a transport selection, choose UDP or TCP according to installation needs.
  5. Save or apply the configuration and push settings to the tracker using the manufacturer tool or confirmed SMS commands.
  6. Restart the device if required by the configurator or after applying network changes.
  7. Validate in Plaspy that the device reports successfully and that telemetry and positions are received.

Example Configuration Commands​

The SIGNAL S-2551 supports multiple manufacturer configuration methods including local USB configurator software and remote SMS or GPRS commands. Exact public command syntax can vary by firmware and tool version. Because manufacturer command sets differ, follow the Navtelekom documentation or the NTC Configurator for the precise command strings and their required order.

If you have a vendor supplied command list or SMS templates from Navtelekom, apply them using the recommended workflow and then verify the data reach d.plaspy.com on port 8888. Plaspy will automatically detect the correct protocol once the device initiates communication to the shared server endpoint.

Configuration Notes​

  • Firmware variations can change available settings and command syntax; always verify your device firmware version before applying commands.
  • TCP and UDP both work with Plaspy on port 8888; choose the transport that best matches your network conditions and installation policy.
  • The SIGNAL S-2551 can be configured to send to up to three servers; when using multiple endpoints, ensure one is set to d.plaspy.com or 54.85.159.138 on port 8888.
  • Use the manufacturer USB configurator for bulk provisioning and for access to advanced I O, CAN, and telemetry mappings.
  • Keep a record of applied settings and validate reporting in Plaspy after each configuration change to confirm successful integration.

Why Use Plaspy with This Configuration​
