iStartek - VT110-L Protocol

This page covers the public protocol context for using the iStartek VT110-L tracker with Plaspy. It explains, in general and non sensitive terms, how the VT110-L reports position, events, and telemetry to the Plaspy platform and what role the reporting protocol plays in reliable fleet and anti theft workflows.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior for the VT110-L can vary with firmware version, hardware revision, and manufacturer implementation, so the guidance below focuses on public, high level communication context rather than firmware internals or private packet formats.

Protocol Overview​

At a high level, the tracker communication protocol defines how the VT110-L identifies itself, transmits GNSS fixes and cellular based location, and sends event or alarm reports to a remote server. For Plaspy integration the protocol enables the device to deliver timely telemetry and status that the platform can use for live monitoring, alerts, and historical analysis.

  • Enables delivery of GNSS fixes, cellular fallback location, and device status to the server for live tracking.
  • Carries event reports such as ignition state, door alarms, impact or vibration, and other inputs that drive platform alerts.
  • Provides the vehicle identifier and relevant metadata so Plaspy can associate incoming messages with the correct asset.
  • Supports remote command and control workflows such as immobilizer commands when paired with platform actions.
  • Allows for over the air configuration and firmware updates where the device and manufacturer support FOTA features.

How Plaspy Detects the Protocol​

Plaspy receives tracker traffic on a shared endpoint and uses the shared connection settings to identify and parse incoming reports automatically. In most typical setups the VT110-L only needs to be configured to report to the Plaspy endpoint and port, and Plaspy will attempt to detect the proper protocol without requiring manual protocol selection in the platform.

  • Devices should be configured to report to the Plaspy endpoint d.plaspy.com or the equivalent server IP address 54.85.159.138.
  • Plaspy accepts connections on port 8888 and uses that same port for all supported devices.
  • Plaspy automatically detects the tracker protocol so manual protocol selection in the platform is usually unnecessary when the device is configured to report correctly.
  • If multiple transport types are supported by the device, Plaspy will accept either UDP or TCP reporting on the shared port when configured accordingly.
  • Proper device identifier and reporting interval configuration on the tracker help Plaspy match incoming messages to the correct asset and ensure reliable ingestion.

Transport and Connection Context​

Transport and connection context covers how the VT110-L connects to Plaspy rather than the internal packet details. The device can use standard cellular data transport over TCP or UDP to send telemetry to the platform endpoint. Correct endpoint configuration and transport selection are central to getting reliable reporting into Plaspy.

  • The VT110-L may be configured to use UDP or TCP to report to the Plaspy endpoint.
  • Plaspy accepts device connections on port 8888 and this is the common port for all devices in the platform.
  • Devices can point to the domain d.plaspy.com or the server IP 54.85.159.138 as the reporting target.
  • Transport selection can affect delivery characteristics such as retransmission behavior and latency depending on network conditions.
  • Ensure APN and SIM data connectivity are functioning on the device to allow cellular delivery of telemetry to Plaspy.

Protocol Compatibility Notes​

  • Compatibility can depend on the VT110-L firmware version and the exact firmware build installed on a device.
  • Hardware revisions or SKU variants may implement features differently; verify the device model and revision when troubleshooting.
  • The device may support both TCP and UDP reporting; confirm which transport is configured in the field and at the carrier level.
  • Manufacturer side settings such as dual server configuration can improve delivery reliability and should be considered during setup.
  • Remote features like FOTA require both device and manufacturer backend support and may influence protocol behavior after updates.
  • Always validate device behavior against current manufacturer documentation for model specific limitations or changes.

Why Protocol Understanding Matters​

A clear, high level understanding of the VT110-L communication protocol helps with setup, troubleshooting, and ensuring long term reliability when devices report to Plaspy. Knowing what the protocol is responsible for makes it easier to interpret platform alerts and manage device configuration across a fleet.

  • Speeds up field configuration by clarifying which settings must point to the Plaspy endpoint and port.
  • Helps diagnose connectivity issues by distinguishing transport level problems from device or firmware issues.
  • Improves alarm and event mapping so platform rules trigger correctly for inputs like ignition, door, and impact detection.
  • Supports planning for firmware updates and understanding when behavior may change after a FOTA event.
  • Guides integration of additional peripherals and sensors by clarifying what data the tracker will supply to Plaspy.

Why Use Plaspy with This Protocol​

Using the VT110-L with Plaspy provides organizations with continuous vehicle visibility, rich event reporting, and workflow options for anti theft and fleet operations. The device’s GNSS plus cellular fallback, event inputs, and immobilizer capabilities pair naturally with Plaspy’s ingestion, alerting, and dispatch features to deliver useful operational insights.

If you want to evaluate how the VT110-L will work in your environment, start by configuring devices to report to d.plaspy.com or 54.85.159.138 on port 8888 using the transport type supported in your deployment.
