ArkNav - RX-9 Protocol
This page describes the public protocol context for using the ArkNav RX-9 tracker with Plaspy. It focuses on how the device communicates with Plaspy in general terms, how connection settings are applied, and what to consider when provisioning RX-9 units for fleet telemetry, anti theft, and temperature controlled logistics. The RX-9 is a rugged IP67 GPS tracker built around uBlox GNSS and cellular modules and is commonly used for vehicles, trailers, and heavy equipment where reliable positioning and robust hardware are important.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a properly configured device reports to the Plaspy endpoint. Exact protocol behavior for the RX-9 can vary with firmware version, hardware revision, accessory configuration, and manufacturer implementation. For network configuration Plaspy accepts traffic on d.plaspy.com and 54.85.159.138 using a single platform port, and RX-9 units may be configured to use UDP or TCP on port 8888 to report to Plaspy.
Protocol Overview
The tracker communication protocol is the set of rules the RX-9 uses to exchange positioning, sensor, and event data with a backend such as Plaspy. It enables the device to identify itself to the server, transmit GPS fixes and telemetry, and signal alerts and state changes. Understanding the protocol at a conceptual level helps installers and administrators ensure the device is configured to reach the Plaspy endpoint and that telemetry maps correctly into the Plaspy platform.
- Transports device location, timestamps, and sensor telemetry to the server so Plaspy can render live positions and historical traces.
- Conveys device identity and status information so Plaspy can associate incoming data with the correct asset and configuration.
- Provides event and alert signals such as ignition, motion, G force events, driver ID, battery level, and temperature that drive rule based notifications in Plaspy.
- Supports periodic heartbeat or keepalive reporting to maintain a reliable session and enable remote management workflows.
- Allows configurable reporting intervals and conditions so deployments can balance update frequency against cellular data usage and battery life.
How Plaspy Detects the Protocol
Plaspy receives incoming reports on a single shared endpoint and automatically detects the tracker protocol for most devices, including the RX-9, when the device is pointed to the platform. Because detection is handled server side, users commonly do not need to select a protocol manually in Plaspy if the device is configured correctly to report to the Plaspy address.
- Plaspy listens on a single platform port for device data and uses automated detection to identify the reporting protocol.
- Devices can be configured to report to the Plaspy domain d.plaspy.com or directly to the IP 54.85.159.138.
- All devices in Plaspy use the same port which simplifies provisioning and firewall configuration.
- Proper device identity and consistent reporting intervals help Plaspy associate data with the correct account and tracker.
- If a device does not appear in Plaspy, verify network settings, APN and that the device is pointing to the correct Plaspy endpoint and port.
Transport and Connection Context
Transport and connection choices determine how the RX-9 sends its reports to Plaspy. The RX-9 supports standard cellular data reporting and can be configured to use either UDP or TCP based on device firmware and deployment requirements. Understanding the connection context helps ensure reliable delivery and correct server addressing.
- RX-9 units may be configured to use UDP or TCP on port 8888 depending on device support and configuration choices.
- Devices can report to the Plaspy server domain d.plaspy.com or directly to the server IP 54.85.159.138.
- Plaspy uses the same port across devices which reduces per device configuration complexity.
- Choose UDP for lower overhead and faster delivery when network reliability is sufficient, or TCP when ordered delivery and connection state are preferred by the firmware.
- Ensure vehicle or fleet network policies allow outbound traffic to the Plaspy endpoint and port to permit successful reporting.
Protocol Compatibility Notes
- Firmware revisions may change field availability, report formats, or supported transport modes. Confirm the RX-9 firmware level when troubleshooting compatibility.
- Hardware revisions and accessory configurations such as external temperature sensors or immobilizers can alter the set of telemetry fields the device reports.
- Manufacturer side defaults and configurable message templates can vary by regional models. Check device configuration when expected fields do not appear in Plaspy.
- Transport selection between UDP and TCP is a configuration option on many units and can affect delivery semantics and retry behavior.
- When integrating at scale, validate a sample unit end to end with Plaspy before mass provisioning to confirm network and reporting behavior.
- Always cross reference device settings such as APN, server address, and reporting intervals with official ArkNav documentation for the specific unit model.
Why Protocol Understanding Matters
A general understanding of the RX-9 communication protocol helps administrators and integrators set up devices correctly, interpret incoming data, and diagnose common connectivity issues without needing low level protocol parsing knowledge. This practical understanding reduces deployment time and improves operational reliability when devices are monitored through Plaspy.
- Ensures correct server address and transport settings so devices reliably reach Plaspy.
- Helps map device telemetry fields to the platform so alerts and rules trigger as intended.
- Aids in troubleshooting lost reports, intermittent connectivity, and data gaps by checking transport, APN, and firmware settings.
- Supports planning for data usage, reporting intervals, and battery life trade offs in fleet deployments.
- Facilitates coordination with ArkNav support or installers when device behavior differs from documentation.
Why Use Plaspy with This Protocol
Using the RX-9 with Plaspy provides a straightforward path to real time vehicle visibility, telemetry monitoring, and rule based alerting for fleets that operate in demanding environments. The RX-9’s rugged design, onboard telemetry sensors, and support for external accessories make it well suited to fleet, trailer, and temperature controlled use cases, while Plaspy handles ingestion, visualization, and alerts for the data the device reports.
