PST - AVL-011 Protocol
This page summarizes the public protocol context for using the PST AVL-011 tracker with Plaspy. It covers how the device typically communicates with the Plaspy platform in broad, non sensitive terms and highlights the parts of the communication setup you will commonly encounter when integrating this model. The AVL-011 is a vehicle tracker with anti theft features, remote power cut capability, stealth installation options, and SOS monitoring that report status and events to a server endpoint.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device is configured to report to the Plaspy endpoint. Exact protocol behavior for the AVL-011 can vary depending on firmware version, hardware revision, and manufacturer implementation, so this page focuses on high level integration points rather than device internals.
Protocol Overview
At a high level the tracker reporting protocol defines how the AVL-011 identifies itself, reports location and status, and signals alarms or remote control events. The protocol enables Plaspy to receive position updates, emergency signals, and operational state in a way that is usable for mapping, alerts, and remote actions.
- Enables the AVL-011 to send periodic location and status reports to a remote server for tracking and monitoring
- Supports transmission of alarm and emergency events such as SOS so Plaspy can trigger alerts and logging
- Allows the device to identify itself so Plaspy can associate incoming data with the correct asset
- Carries operational state information relevant to anti theft features and remote immobilization requests
- Provides a consistent stream of telemetry that Plaspy uses for display, notifications, and historical records
How Plaspy Detects the Protocol
Plaspy receives device connections on a shared endpoint and port and automatically determines which tracker protocol is in use. That means in most cases you do not need to manually select a protocol in Plaspy as long as the AVL-011 is configured to report to the Plaspy endpoint and port.
- Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138
- The Plaspy listening port is 8888 and all devices in Plaspy use the same port
- The device may be configured using UDP or TCP on port 8888 depending on device support and configuration
- Plaspy automatically detects the tracker protocol when data arrives at the shared endpoint
- If the tracker is set to report to d.plaspy.com or 54.85.159.138 on port 8888, Plaspy will receive the device data for processing
Transport and Connection Context
Connection and transport choices determine how the AVL-011 delivers messages to Plaspy but do not change the high level reporting goals. The most important integration items are the destination address and port and whether the device is set to use UDP or TCP.
- Devices commonly point to the Plaspy domain d.plaspy.com or the IP address 54.85.159.138
- The configured destination port for Plaspy is 8888 and this same port is used for every device supported by Plaspy
- The AVL-011 may operate over UDP or TCP to send reports depending on model configuration and firmware
- Network stability and SIM connectivity affect how reliably reports reach Plaspy over either transport
- Ensure the tracker is configured to use the correct endpoint and port so incoming data arrives at Plaspy without manual protocol selection
Protocol Compatibility Notes
- Firmware variations across AVL-011 production batches can change which features are available or how some messages are reported
- Hardware revisions and optional wiring for immobilization or SOS may require specific setup steps noted in manufacturer documentation
- The choice of transport TCP or UDP can be selectable on the device and should match the configuration used when validating connectivity to Plaspy
- Manufacturer side configuration menus or SMS commands may be required to point the device to d.plaspy.com or 54.85.159.138 on port 8888
- Feature behavior such as remote power cut or voice monitoring may depend on firmware and how the device is installed
- Always validate compatibility and supported features against the manufacturer documentation for the specific firmware revision
Why Protocol Understanding Matters
Knowing the communication protocol and connection context helps you set up the AVL-011 correctly, speeds troubleshooting, and reduces downtime when integrating with Plaspy. A clear picture of how the device reports and what it is capable of ensures reliable tracking and alarm handling.
- Helps verify that the device is pointing at the correct Plaspy endpoint and port
- Aids in diagnosing why a device might not appear in Plaspy or why messages are incomplete
- Clarifies which features are driven by device messages versus server side configuration
- Supports planning for firmware updates and feature testing to preserve expected behavior
- Improves confidence when enabling critical functions like immobilization and SOS monitoring
Why Use Plaspy with This Protocol
Using the PST AVL-011 with Plaspy provides a centralized way to collect location, alarm, and operational state for fleets or individual vehicles. Plaspy consolidates incoming telemetry from the tracker so organizations can monitor movement, respond to SOS alerts, and act on anti theft events from a single platform while preserving the device capability to operate discreetly.
