V-SUN - TLT-7B Protocol

This page presents the public protocol context for using the V-SUN TLT-7B tracker with Plaspy. It summarizes how the device commonly communicates, the role of the reporting protocol in getting usable position and status data to Plaspy, and practical factors to consider when configuring or validating connectivity. The TLT-7B is a 3G tracker with strong positioning performance and multiple reporting options that make it a flexible option for vehicle and asset tracking.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior can vary with firmware version, hardware revision, or manufacturer configuration, so this page focuses on public, non sensitive connection context. For Plaspy the primary server endpoint is d.plaspy.com (54.85.159.138) using port 8888 and devices may be configured to reach that endpoint over UDP or TCP.

Protocol Overview​

The tracker reporting protocol defines how the TLT-7B formats and sends position, status, and event data so Plaspy can interpret and present it. At a high level this protocol is the bridge between the device’s sensors and Plaspy’s telemetry ingestion, and it supports key features such as periodic position uploads, event driven messages, and diagnostic reporting.

  • Enables the TLT-7B to send GPS positions, movement events, and device status to a remote server for processing.
  • Provides device identification and session context so Plaspy can associate incoming data with a specific tracker.
  • Conveys important telemetry such as location, time, and event types that Plaspy uses for mapping, alerts, and history.
  • Allows the tracker to use cellular data channels (for example GPRS TCP) or alternative channels like SMS for reporting depending on configuration.
  • Supports event-driven reports for SOS, geofence triggers, power alerts, and other useful alarms the device can produce.

How Plaspy Detects the Protocol​

Plaspy’s ingestion endpoint is designed to accept connections from many common tracker models and automatically identify the protocol used by each device once it starts reporting. When a TLT-7B is configured to send data to the Plaspy endpoint, the platform matches incoming traffic to the correct processing routine without requiring a manual protocol selection in most cases.

  • The public Plaspy server domain is d.plaspy.com and its public IP is 54.85.159.138.
  • Plaspy listens on port 8888 for incoming tracker connections and all devices in Plaspy use the same port.
  • Devices may be configured to use either UDP or TCP to send data to the Plaspy endpoint on port 8888.
  • If the TLT-7B is pointed at the Plaspy endpoint and correctly identifies itself in its reports, Plaspy will automatically detect its protocol.
  • In typical setups users do not need to pick a protocol inside Plaspy if the device is properly configured to report to d.plaspy.com on the shared port.

Transport and Connection Context​

Connection context covers how the TLT-7B reaches Plaspy and which channels are commonly used for reporting. The TLT-7B supports typical cellular reporting options and can deliver its data to Plaspy over standard network transports.

  • The device may be configured using UDP or TCP on port 8888 depending on device support and the operator configuration.
  • Plaspy accepts connections at d.plaspy.com and at the IP address 54.85.159.138 on the same port.
  • All devices in Plaspy use the same port, which simplifies firewall and network planning for fleets.
  • The TLT-7B can also send position information by SMS in scenarios where GPRS is not available, while online reporting commonly uses GPRS with TCP.
  • Choosing UDP or TCP can affect delivery guarantees and network behavior; select the transport supported by your carrier and device firmware.

Protocol Compatibility Notes​

  • Firmware versions and regional hardware revisions can change how the tracker formats reports or which features are available.
  • Manufacturer settings may expose different configuration commands or parameter names across firmware releases.
  • Transport choice (UDP versus TCP) must match the device configuration and any network constraints applied by the SIM carrier.
  • Features such as SOS, geofencing, fuel cutoff alerts, and OBD II data reporting depend on the specific device build and connected sensors.
  • Validate device compatibility by testing a unit configured to report to d.plaspy.com on port 8888 before large deployments.
  • Always compare observed behavior to the official manufacturer documentation for the exact firmware build in use.

Why Protocol Understanding Matters​

Having a practical understanding of how the TLT-7B communicates helps ensure reliable setup and long term operation with Plaspy. While Plaspy handles protocol detection and ingestion, operators and integrators benefit from knowing what the tracker is expected to send and how network choices influence delivery.

  • Faster troubleshooting when a device is not appearing in Plaspy because you can confirm transport, server address, and SIM connectivity.
  • Better deployment planning by choosing the appropriate transport and verifying that the carrier provides the necessary IP routing.
  • More accurate alerting and history by confirming which event types and parameters the device is sending.
  • Easier firmware and configuration updates when you understand which options affect server reporting and feature availability.
  • Reduced integration time for large fleets by standardizing device configuration to report to the Plaspy endpoint.

Why Use Plaspy with This Protocol​

Using the V-SUN TLT-7B with Plaspy gives organizations a centralized way to collect position and event data from this capable 3G tracker. Plaspy’s shared endpoint model and automatic protocol detection simplify device onboarding and allow teams to focus on operational use cases like geofencing, overspeed monitoring, and historical route analysis.

Plaspy centralizes telemetry from many devices and supports the common reporting paths used by the TLT-7B, reducing configuration overhead for mixed fleets.
