NVS - SIGNAL S-2115 Protocol
This page documents the public protocol context for integrating the NVS SIGNAL S-2115 tracker with the Plaspy fleet platform. It focuses on high level communication and connection details that matter when reporting device data into Plaspy, without exposing private implementation or firmware internals. The SIGNAL S-2115 is an automotive mobile set using GNSS constellations and an open information exchange protocol, which enables integration with third party tracking systems.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device reports to the platform. Exact protocol behavior for the SIGNAL S-2115 can vary by firmware version, hardware revision, and manufacturer configuration, so the notes here are meant as general guidance rather than a firmware specific manual.
Protocol Overview
The tracker protocol is the on device communication method that packages GNSS fixes, status, and alarms for transmission to a remote server. For the SIGNAL S-2115, the open protocol of information exchange makes it suitable to report location and telemetry into third party systems such as Plaspy while allowing manufacturers or integrators to adapt message contents.
- Enables the tracker to identify itself and send location, time, and status information to a backend.
- Carries telemetry used for monitoring, alarms, and basic diagnostics relevant to fleet workflows.
- Provides a consistent channel for the device to report into Plaspy while firmware defines exact fields and behavior.
- Allows integration with dispatch and monitoring systems by using a documented, open exchange format.
- Supports use cases such as route tracking, alarm reporting, and periodic position updates.
How Plaspy Detects the Protocol
Plaspy receives device reports on a shared endpoint and port and performs protocol selection automatically for incoming connections. In most cases you do not need to choose a protocol inside Plaspy if the SIGNAL S-2115 is configured to report to the Plaspy endpoint and uses a supported transport.
- Plaspy listens on the public server domain d.plaspy.com and accepts connections directed to that host.
- The platform is also reachable at the known server IP 54.85.159.138 for environments that require IP based configuration.
- Plaspy uses a common listening port for all supported devices which simplifies device setup and inbound handling.
- Devices reporting to the Plaspy endpoint are examined and matched to a parser automatically so manual protocol selection is usually unnecessary.
- Proper device configuration to point at the Plaspy endpoint and use the supported transport is the most common requirement to enable automatic detection.
Transport and Connection Context
Connection setup is a separate concern from message content; the SIGNAL S-2115 can be configured to use different transport types depending on device capabilities and local network conditions. Plaspy supports both common transport modes on its shared port to accept reports from a wide range of trackers.
- The device may be configured to use UDP or TCP on port 8888 depending on the model firmware and network environment.
- Plaspy accepts tracker reports on port 8888 and all devices supported by Plaspy use this same port.
- Devices may be pointed to the Plaspy domain d.plaspy.com or to the server IP 54.85.159.138 when DNS or firewall constraints require it.
- Use the transport mode that best fits your network and device documentation; some installations prefer UDP for simplicity while others use TCP for reliable session delivery.
- Ensure outbound traffic to the Plaspy endpoint and port is permitted by network firewalls and carrier APN settings.
Protocol Compatibility Notes
- The SIGNAL S-2115 implements an open information exchange protocol but exact message fields and triggers can vary across firmware releases.
- Hardware revisions and the NV08C receiver firmware may affect available GNSS features and message timing.
- Manufacturer configuration options or regional firmware builds can change which transport or ports are recommended by NVS.
- Choosing UDP or TCP can influence delivery characteristics; validate which transport is active on your devices before large scale rollout.
- Confirm device reporting settings (destination host, transport, port) against Plaspy endpoint values to avoid misrouting.
- For mission critical deployments, perform a small pilot to confirm messages arrive and are parsed as expected by Plaspy.
Why Protocol Understanding Matters
A basic understanding of the tracker reporting protocol helps with initial setup, diagnosing reporting issues, and ensuring long term reliability when using Plaspy. Knowing how the SIGNAL S-2115 packages and sends data reduces setup time and makes troubleshooting more efficient.
- Simplifies device provisioning by confirming the correct destination host and transport are configured.
- Speeds troubleshooting when position updates or alarms fail to appear in Plaspy by focusing checks on transport and reporting intervals.
- Helps anticipate differences between firmware versions that can change message frequency or field availability.
- Supports operational decisions about which transport to standardize on for a fleet.
- Enables clear communication with NVS support if device behavior differs from expectations.
Why Use Plaspy with This Protocol
Using the NVS SIGNAL S-2115 with Plaspy provides organizations with a straightforward path to ingest GNSS tracking and alarm data into a single fleet management platform. The SIGNAL S-2115’s open exchange protocol and certified GNSS receiver make it a practical choice for vehicle monitoring, while Plaspy’s automatic protocol detection and unified port handling reduce configuration overhead.
