ATrack - AX5 Protocol
This page provides public protocol context for using the ATrack AX5 tracker with the Plaspy platform. It focuses on how the AX5 communicates in general terms, what connection settings are commonly used to report data to Plaspy, and what aspects of the tracker and its protocol are relevant for successful integration and day to day operation.
The AX5 is compatible with Plaspy and supports GPRS, TCP, and UDP connections from the vehicle via its OBD II interface or auxiliary wiring. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol. Exact protocol behavior can vary with firmware version, hardware revision, and manufacturer implementation, so some device specific differences are expected in practice.
Protocol Overview
The protocol of a tracker like the ATrack AX5 defines how it identifies itself, sends telemetry, and reports OBD II or CAN Bus data to a central server. When integrated with Plaspy, the tracker uses network transport to deliver GPS position, vehicle inputs, and event records so the platform can display and act on those messages.
- The tracker protocol carries location, timestamp, movement status, and event flags from the device to the server.
- OBD II and CAN Bus telemetry from the AX5 is transmitted alongside GPS and status data when configured to report to the server.
- Protocol behavior determines how the device identifies itself to the server so Plaspy can correlate messages with a device record.
- The protocol enables reporting of internal events such as panic inputs, sleep mode transitions, and backup battery status.
- Firmware updates via GPRS and internal memory use the device communication channel but depend on manufacturer procedures and server support.
How Plaspy Detects the Protocol
Plaspy receives device reports on a shared endpoint and uses automated detection to recognize the tracker protocol so users normally do not need to manually select a protocol inside the platform. If the AX5 is configured to report to the Plaspy endpoint using the correct connection settings, Plaspy will map incoming data to a device.
- Plaspy automatically detects the tracker protocol from incoming connections and message patterns.
- The Plaspy server domain is d.plaspy.com and the Plaspy server IP is 54.85.159.138.
- The port is 8888 and all devices in Plaspy use the same port for reporting.
- When the AX5 reports to the Plaspy endpoint, the platform matches the device identity and begins processing received telemetry.
- Users typically do not need to choose a protocol manually in Plaspy when the tracker is properly configured to send data to the platform.
Transport and Connection Context
Transport selection is an implementation detail of the AX5 and can be configured per device or dictated by firmware. The tracker may use UDP or TCP to send reports; both transports are supported when the device points to the Plaspy endpoint on the shared port.
- The device may be configured using UDP or TCP on port 8888 depending on device support and configuration.
- Devices may point to d.plaspy.com or 54.85.159.138 as the reporting target for Plaspy.
- Plaspy uses the same port for all supported devices which simplifies device setup and server-side routing.
- GPRS is commonly used to provide the IP connectivity required for TCP or UDP reporting from the vehicle.
- Transport behavior such as retry strategy and keepalive is governed by AX5 firmware settings and network conditions.
Protocol Compatibility Notes
- Firmware revisions can change message behavior, available fields, and transport preferences; always note the device firmware level when troubleshooting.
- Hardware revisions or optional connectors such as OBD II or external CAN Bus interfaces can affect which telemetry is available to send.
- Manufacturer configuration defaults may use either UDP or TCP, so confirm the device is set to report to Plaspy on the correct transport.
- Manufacturer side variations in command support or optional features can affect remote configuration and firmware update methods.
- Plaspy’s automatic detection reduces the need for manual protocol selection but validating the device is pointed at d.plaspy.com or 54.85.159.138 on port 8888 is essential.
- Validate compatibility and any advanced features against the manufacturer documentation for the specific firmware and hardware revision.
Why Protocol Understanding Matters
Understanding the tracker communication protocol helps ensure reliable reporting, correct data interpretation in Plaspy, and effective troubleshooting when messages are missing or malformed.
- Confirms the device is pointed to the correct Plaspy endpoint and using the expected transport.
- Helps distinguish network issues from device configuration or firmware behavior.
- Supports correct mapping of OBD II and CAN Bus parameters into fleet telematics workflows.
- Improves planning for firmware updates and remote configuration that rely on the device communication channel.
- Enables faster resolution when devices enter sleep mode or use backup memory to store and forward data.
Why Use Plaspy with This Protocol
Using the ATrack AX5 with Plaspy provides a straightforward path to vehicle level visibility and fleet management while keeping setup consistent across a mixed device estate. The AX5’s OBD II connectivity, CAN Bus support, and GPRS reporting make it suitable for common telematics use cases where rapid installation and reliable reporting matter.
