TZone - TZ-AVL19 Protocol

This page covers the public protocol context for using the TZone TZ-AVL19 GPS tracker with the Plaspy platform. It explains, at a high level, how the device typically reports location, events, and status information to Plaspy and what aspects of the tracker communication are relevant when integrating or troubleshooting the device. The intent is to provide practical guidance without exposing private implementation details.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol. Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138. The port is 8888 and the device may be configured using UDP or TCP on port 8888. All devices in Plaspy use the same port. Exact packet behavior and feature availability can vary by TZ-AVL19 firmware, hardware revision, and manufacturer implementation, so you should verify device-specific options when configuring a tracker.

Protocol Overview​

The tracker communication protocol defines how the TZ-AVL19 reports position, alarms, input states, and telemetry to a remote server so the data can be used by a fleet platform such as Plaspy. In general, the protocol acts as the language the device speaks to deliver timely and usable information about vehicle location and status.

  • Enables periodic or event driven location reporting for single position or continual tracking modes.
  • Encodes alarm and input events such as over speed, geo-fence, SOS, tremble, parking, and low battery for server processing.
  • Carries discrete vehicle control and status indicators such as door open close and engine on off to support monitoring or remote actions.
  • Supports multiple transport methods so the device can send data over GPRS using either TCP or UDP and fall back to SMS where applicable.
  • Allows optional telemetry and sensor data to be transmitted when available, for example fuel level, temperature sensors, and accelerometer events.

How Plaspy Detects the Protocol​

Plaspy accepts connections to a single shared endpoint and automatically determines which tracker protocol is in use for incoming data. When a TZ-AVL19 is configured to report to the Plaspy endpoint, the platform will match incoming messages to a compatible handler so manual protocol selection inside Plaspy is typically not required.

  • Plaspy server domain is d.plaspy.com which devices can use as their reporting host.
  • Plaspy server IP is 54.85.159.138 and devices can be pointed to this address if DNS is not used.
  • The port is 8888 and this is the common port Plaspy uses for all device connections.
  • The device may be configured using UDP or TCP on port 8888 depending on device support and configuration preferences.
  • Plaspy automatically detects the tracker protocol so users normally do not need to select a protocol in the platform if the device is sending to the correct Plaspy endpoint.

Transport and Connection Context​

Connection context is an important practical detail when configuring a TZ-AVL19 to report to Plaspy. The tracker can use GPRS to send real time data to Plaspy over the network, and the choice of TCP or UDP impacts delivery behavior and network considerations such as firewall rules.

  • The device may be configured using UDP or TCP on port 8888 according to what the tracker firmware and network conditions support.
  • Devices may point to d.plaspy.com or 54.85.159.138 as the Plaspy endpoint; using the DNS name simplifies changes on the server side.
  • The port is 8888 and all devices in Plaspy use the same port for consistency across models.
  • TCP provides connection oriented delivery while UDP offers reduced overhead; the TZ-AVL19 supports reporting over either transport in typical configurations.
  • Some installations also use SMS as a fallback for critical alerts if data connectivity is unavailable, depending on the tracker configuration.

Protocol Compatibility Notes​

  • The TZ-AVL19 is compatible with Plaspy when configured to report to the Plaspy endpoint, but exact message content and available features can depend on the device firmware version.
  • Hardware revisions or optional modules such as SD card logging, external camera or RFID reader support can change which fields or events the tracker sends.
  • Manufacturer-side configuration and default settings may require enabling GPRS reporting or selecting the TCP/UDP transport before Plaspy will receive data.
  • Network conditions, APN settings, and SIM provisioning on the device can affect connectivity to d.plaspy.com or 54.85.159.138 on port 8888.
  • SMS reporting and other fallbacks are governed by device settings; confirm whether SMS is used for alarm forwarding or as a transport fallback.
  • Always validate compatibility against the latest manufacturer documentation and firmware release notes for TZ-AVL19.

Why Protocol Understanding Matters​

Knowing how the TZ-AVL19 communicates helps ensure a smooth setup, reliable data flow, and effective troubleshooting when working with Plaspy. A practical understanding of the communication context reduces setup time and helps pinpoint issues when telemetry or events are not arriving as expected.

  • Ensures the device is pointed to the correct Plaspy endpoint and using the supported transport method.
  • Helps distinguish between connectivity problems and device configuration issues such as disabled reporting or incorrect APN.
  • Guides decisions about using TCP versus UDP for specific operational needs like timely alarms or lower bandwidth usage.
  • Supports planning for optional features such as external sensors, SD logging, or two way voice which may affect reporting behavior.
  • Assists in coordinating firmware updates and manufacturer support inquiries by providing clear information about observed behavior.

Why Use Plaspy with This Protocol​

Pairing the TZone TZ-AVL19 with Plaspy gives organizations a practical way to collect real time location, alarms, and vehicle status in a single platform. For fleet managers, the combination of TZ-AVL19 hardware features and Plaspy visibility supports route oversight, incident response, and operational reporting without manual polling of devices.
