Navtelekom - СИГНАЛ S-2652 Protocol
This page describes the public protocol context for using the Navtelekom СИГНАЛ S-2652 tracker with the Plaspy platform. It focuses on how the device communicates in general terms, what connection settings are used to reach Plaspy, and what to consider when integrating the tracker for real time tracking, telemetry, and event reporting. The information here is intended to help administrators and integrators understand the communication role of the device without exposing sensitive implementation details.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol once the device reports to the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so this page emphasizes connection and compatibility context rather than device internals. The SIGNAL S-2652 is discontinued by the manufacturer but remains useful in many legacy installations where its I O and logging features are required.
Protocol Overview
The protocol used by the SIGNAL S-2652 enables the tracker to report GNSS position, telemetry, and event data to a remote server so that a fleet platform like Plaspy can ingest and present the information. At a high level the tracker protocol carries location updates, input and output states, and telemetry gathered from serial, CAN, and onboard sensors.
- Provides GNSS and timestamped location reporting for real time tracking and historical replay.
- Transmits status of universal inputs and controllable outputs so Plaspy can represent ignition, door, and immobilizer events.
- Conveys telemetry from CAN and serial interfaces for fuel monitoring, diagnostics, and sensor integration.
- Supports local microSD logging to preserve records during network outages and forward them to Plaspy when connectivity is restored.
- Uses the device modem to deliver event driven alerts and periodic reports to the configured server endpoint.
How Plaspy Detects the Protocol
Plaspy is designed to accept connections from many tracker models on a common endpoint and determine the correct protocol automatically when a device connects and reports. This reduces the need for manual protocol selection within the Plaspy platform when the tracker is configured to send data to Plaspy.
- Plaspy's public endpoint is reachable at d.plaspy.com and the server IP 54.85.159.138 for device reporting.
- The central port used by Plaspy for device connections is 8888 and is the same port for all supported devices.
- Devices can be configured to use either UDP or TCP on port 8888 depending on device capability and network requirements.
- When a properly configured device reports to the Plaspy endpoint Plaspy automatically detects the tracker protocol so manual selection is typically unnecessary.
- Ensure the tracker is pointed to the correct Plaspy host and port and that mobile network settings such as APN and SIM configuration are valid.
Transport and Connection Context
Understanding the transport layer and how the tracker reaches Plaspy is essential for reliable operation. The SIGNAL S-2652 uses its cellular modem to send data over the mobile network to the configured server address and port. Network behavior, such as retries and connection mode, depends on the device firmware and configuration.
- The device may be configured using UDP or TCP on port 8888 depending on device support and installer preference.
- Pointing the device at d.plaspy.com or the IP 54.85.159.138 will direct traffic to Plaspy for parsing and ingestion.
- Plaspy uses the same port for all devices which simplifies server side settings and device provisioning.
- Cellular settings such as dual SIM selection and APN must be configured on the device to maintain connectivity.
- Local microSD logging helps bridge gaps when connections drop and allows later upload to Plaspy once connectivity is restored.
Protocol Compatibility Notes
- The SIGNAL S-2652 is compatible with Plaspy for real time tracking and telemetry when configured to report to the Plaspy endpoint.
- Protocol behavior may vary between firmware versions and hardware revisions; always check firmware release notes before deploying changes.
- Because the model is discontinued there may be manufacturer recommendations for replacement devices that offer newer cellular standards.
- Transport choice of UDP or TCP can affect delivery guarantees and should be matched to operational needs and network conditions.
- Manufacturer side configuration tools and remote management systems may affect how the device sends reports and receives updates.
- Validate device reporting by confirming the tracker is pointed to d.plaspy.com or 54.85.159.138 on port 8888 and by monitoring the device connection status in Plaspy once data begins arriving.
Why Protocol Understanding Matters
A practical understanding of the device protocol and connection context helps ensure successful setup and long term reliability with Plaspy. Knowing what the protocol carries and how the device reaches the platform reduces troubleshooting time and improves data quality for fleet operations.
- Makes initial provisioning easier by clarifying which host and port the device must report to.
- Helps diagnose common connectivity issues such as incorrect APN, SIM problems, or transport mismatch.
- Informs decisions about choosing UDP or TCP based on network reliability and expected data patterns.
- Clarifies expectations for data that will be available in Plaspy such as input events, CAN telemetry, and logged records.
- Supports maintenance planning by recognizing the impact of firmware updates and hardware revisions on reporting behavior.
Why Use Plaspy with This Protocol
Using the SIGNAL S-2652 with Plaspy provides a practical way to extend visibility and control across vehicles that require industrial I O and onboard logging. Plaspy can ingest position, event, and telemetry data from the device and surface it in dashboards, reports, and alerting workflows useful for operations, compliance, and theft prevention.
Plaspy simplifies the network side of integration by listening on a single public endpoint at d.plaspy.com or 54.85.159.138 using port 8888 and automatically detecting the tracker protocol.
