Navtelekom - СИГНАЛ S-2114 Protocol

This page covers the public protocol context for using the Navtelekom СИГНАЛ S-2114 tracker with Plaspy. It explains how the S-2114 communicates in broad terms and how those communications are handled by Plaspy for real time tracking, fuel telemetry via RS-232, and alarm reporting. The S-2114 is a discontinued model intended for legacy maintenance and replacement support, and this documentation focuses on non sensitive, high level protocol information useful to integrators and fleet operators.

Plaspy uses shared connection settings for supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior and supported features can vary with firmware revision, hardware revision, and manufacturer implementation, so this page aims to clarify the role of the communication channel without describing firmware internals or private parser details.

Protocol Overview​

The device reporting protocol is the set of messages and transport behavior the tracker uses to deliver position, telemetry, and event data to a remote server. For the S-2114 this includes GPS position, telemetry such as fuel sensor readings from RS-232, and alarm events that Plaspy can capture or log. The protocol enables the tracker to identify itself to Plaspy and deliver usable location and status data for fleet workflows.

  • Carries GPS position and timing information so Plaspy can map and time stamp locations.
  • Delivers telemetry fields such as fuel sensor readings from the RS-232 interface to Plaspy dashboards.
  • Reports device events and alarms that can be associated with vehicle status and security workflows.
  • Supports remote configuration and firmware update workflows over cellular GPRS where the device and manufacturer firmware permit.
  • Enables the tracker to identify itself so Plaspy can associate incoming data with a specific asset record.

How Plaspy Detects the Protocol​

Plaspy receives incoming connections at a shared endpoint and uses connection characteristics and device reports to determine the appropriate protocol handler. This makes setup simpler for end users because the platform typically does not require manual protocol selection if the tracker is configured to report to Plaspy.

  • Plaspy server domain for device reporting is d.plaspy.com.
  • Plaspy server IP address is 54.85.159.138 and the common reporting port is 8888.
  • Devices may be configured to use either UDP or TCP on port 8888 depending on the tracker configuration.
  • All devices in Plaspy use the same port, so there is no per device port configuration required on the server side.
  • When a properly configured S-2114 reports to the Plaspy endpoint, the platform automatically detects the tracker protocol and associates messages to the correct device record.

Transport and Connection Context​

The S-2114 delivers its reports over cellular GPRS to a remote Plaspy endpoint. Connection choices such as UDP or TCP and the destination server address must match the device configuration to ensure reliable data delivery. This section focuses on the connection context rather than message internals.

  • The device may be configured using UDP or TCP on port 8888 depending on device firmware and settings.
  • Devices can be pointed to the Plaspy reporting domain d.plaspy.com or directly to the IP address 54.85.159.138.
  • Plaspy uses the same port 8888 for all supported devices to simplify server side routing and detection.
  • Cellular network behavior and carrier NAT can affect device reachability and should be considered during deployment.
  • Verify the device APN and GPRS data settings in the tracker configuration to enable outbound reporting to the Plaspy endpoint.

Protocol Compatibility Notes​

  • The S-2114 is an archived discontinued model; manufacturer firmware versions and archives are important when validating compatibility.
  • Different firmware releases or hardware revisions can change which telemetry fields are available or how they are encoded.
  • Transport selection between UDP and TCP is dependent on device firmware and settings and can affect reliability and delivery semantics.
  • RS-232 fuel sensor behavior and signal mapping depend on the connected sensor and the device firmware configuration.
  • Alarm reporting via voice call and SMS is a device feature; how those events are represented in Plaspy may differ from direct binary telemetry messages.
  • Always validate compatibility against the manufacturer documentation and firmware release notes before planning wide deployments.

Why Protocol Understanding Matters​

Understanding how the tracker communicates helps ensure a smooth setup, accurate telemetry ingestion, and efficient troubleshooting when devices move from installation to day to day operation in Plaspy. A clear view of protocol and transport context reduces integration friction and supports long term reliability.

  • Ensures correct transport settings so the device can reach Plaspy at d.plaspy.com or 54.85.159.138 on port 8888.
  • Helps map telemetry fields such as RS-232 fuel readings to Plaspy’s data model and dashboards.
  • Makes troubleshooting easier when devices fail to report or when events are missing from the platform.
  • Guides decisions about firmware updates or device replacement for legacy fleets.
  • Supports planning for carrier behavior, APN configuration, and NAT traversal that impact connectivity.

Why Use Plaspy with This Protocol​

Using the Navtelekom СИГНАЛ S-2114 with Plaspy provides a straightforward path to bring legacy vehicle trackers into a modern fleet management environment. Plaspy consolidates GPS positions, fuel telemetry from RS-232 sensors, and alarm events for centralized visibility, allowing operators to maintain continuity for older installations without rebuilding integration stacks.
