ArkNav - R-9PRO Protocol

This page describes the public protocol context for using the ArkNav R-9PRO tracker with the Plaspy platform. It focuses on how the tracker communicates with Plaspy in general terms, what connection settings are used publicly, and which considerations matter when integrating the R-9PRO for fleet tracking, telemetry, and anti theft workflows.

The R-9PRO is a rugged vehicle tracker that uses GNSS positioning and GPRS data transmission and supports over the air updates and a broad set of I O options. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device is configured to report to the Plaspy endpoint. Exact protocol behavior can vary depending on firmware version, hardware revision, and manufacturer implementation, so final compatibility and behavior depend on the shipped device firmware and configuration.

Protocol Overview​

The R-9PRO communication protocol defines how the device reports position, sensor states, and alerts to a remote server and how remote commands and remote management are initiated by the management platform. For Plaspy use, this protocol provides the necessary information to present live location, telemetry, and event data in dashboards and reports without exposing vendor private internals.

  • Enables the R-9PRO to report GNSS position and vehicle telemetry to a remote fleet server.
  • Allows the tracker to identify itself and its configured sensors so Plaspy can map incoming data to device records.
  • Carries event notifications such as ignition state, alarms, panic alerts, and analog sensor readings for timely alerts.
  • Supports remote maintenance and configuration flows such as OTA updates and parameter changes when allowed by the device.
  • Provides the transportable data that Plaspy ingests for geofencing, history, and telematics analysis.

How Plaspy Detects the Protocol​

Plaspy receives incoming connections on a shared server endpoint and port and automatically detects the tracker protocol from the incoming stream when a device is properly configured to report to that endpoint. This automatic detection means most users do not need to choose a protocol manually inside Plaspy when the device is sending to the correct Plaspy address and port.

  • Plaspy listens on a single shared port for device reports and uses the incoming connection to identify the device and its protocol.
  • When an R-9PRO sends reports to the Plaspy endpoint, Plaspy will match the device by its identifiers and apply the appropriate parsing and mapping.
  • In many cases the device only needs to be configured to report to the Plaspy endpoint and no manual protocol selection is required.
  • If a device uses multiple transport modes, ensure the active transport is configured to use the Plaspy endpoint for detection to succeed.
  • Automatic detection reduces setup steps but verifying device identifiers and reporting settings is recommended during first time deployments.

Transport and Connection Context​

The R-9PRO can be configured to send its telemetry using either UDP or TCP depending on device firmware and user configuration. For reporting to Plaspy, devices should be pointed to the public Plaspy server endpoint and port so incoming data reaches the Plaspy ingestion service.

  • Plaspy server domain for device reporting is d.plaspy.com.
  • Plaspy server IP address is 54.85.159.138.
  • Plaspy uses port 8888 for device connections and all devices supported by Plaspy use the same port.
  • The R-9PRO may be configured to use either UDP or TCP on port 8888 depending on the hardware firmware and configuration choices.
  • Confirm the device network APN and GPRS settings are correct for reliable reporting over mobile networks.

Protocol Compatibility Notes​

  • Firmware changes can alter message timing, available fields, and optional features; always check the device firmware version when validating compatibility.
  • Hardware revisions and optional variants such as waterproof models may have slight differences in available I O or sensor wiring that affect telemetry.
  • Transport choice matters some devices behave differently over UDP versus TCP with respect to retransmission and session handling.
  • Manufacturer configuration options such as reporting intervals and enabled sensors influence what Plaspy receives and displays.
  • Verify that the device is configured to send data to the Plaspy endpoint and that any carrier restrictions on 2G GPRS are accounted for.
  • For the most precise device specific behavior consult the ArkNav product documentation and release notes.

Why Protocol Understanding Matters​

Knowing how the R-9PRO communicates helps ensure reliable data flow to Plaspy, speeds troubleshooting, and supports predictable behavior for alerts and remote actions. Understanding protocol context is useful for system integrators, fleet administrators, and support teams during deployment and operations.

  • Helps diagnose why a device is not appearing in Plaspy by checking transport, endpoint, and device identifiers.
  • Guides correct configuration of reporting intervals and sensor mappings so Plaspy receives useful telemetry.
  • Informs decisions about using UDP versus TCP based on network reliability and carrier behavior.
  • Supports planning for OTA updates and parameter changes without interrupting critical tracking functions.
  • Reduces trial and error by aligning device settings with Plaspy expected reporting approaches.

Why Use Plaspy with This Protocol​

Using the ArkNav R-9PRO with Plaspy gives fleet operators centralized visibility into vehicle location, I O events, and sensor telemetry. The R-9PRO hardware features such as extensive I O, internal backup battery, and OTA capability combine with Plaspy dashboards, alerts, and reporting to provide practical operational oversight for fleets, anti theft workflows, and telemetry driven maintenance.
