GOTOP - C790-Y Protocol

This page summarizes the public protocol context for using the GOTOP C790-Y tracker with Plaspy. It focuses on how the device communicates its GNSS position and vehicle telemetry to Plaspy using the public connection settings and common reporting methods, and what to consider when integrating the tracker into a Plaspy deployment.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device is configured to report to the platform. Exact protocol behavior and message timing can vary by firmware version, hardware revision, and manufacturer implementation, so this page focuses on public, non sensitive integration context and practical considerations rather than firmware internals.

Protocol Overview​

The C790-Y uses GNSS positioning (GPS and BeiDou) and GPRS for uplink to a remote server. Its reporting protocol carries position fixes, event flags (for example ACC, overspeed, geofence, SOS), and vehicle telemetry so Plaspy can display live location, generate alerts, and store route history for playback.

  • Enables the tracker to identify itself and send periodic or event driven location updates to Plaspy.
  • Delivers vehicle status and alarm events such as ACC detection, SOS, vibration, and remote fuel cut off to the platform.
  • Allows Plaspy to correlate incoming telemetry with device identity for mapping, alerts, and historical route playback.
  • Supports both continuous reporting and event driven uploads to balance detail and mobile data use.
  • Provides the fundamental data needed by Plaspy to perform geofencing, overspeed detection, and historical playback up to the device retention capabilities.

How Plaspy Detects the Protocol​

Plaspy receives tracker traffic on a shared, public endpoint and automatically detects the device protocol when data arrives. For most deployments the user only needs to configure the device to report to the Plaspy endpoint; the platform handles identifying the tracker format and routing telemetry into the correct device record.

  • Plaspy listens on the public endpoint d.plaspy.com and the corresponding IP 54.85.159.138.
  • The service uses port 8888 for device connections and all devices supported by Plaspy use the same port.
  • Plaspy automatically detects the tracker protocol so manual protocol selection inside the platform is usually unnecessary if the device correctly reports to the endpoint.
  • Proper device configuration to point at the Plaspy endpoint and correct APN/GPRS settings on the SIM card are common setup steps.
  • Because detection is automatic, testing a device connection is typically the fastest way to confirm proper integration.

Transport and Connection Context​

The C790-Y uses GPRS as the cellular transport to deliver messages to Plaspy, and the device may be configured to use either UDP or TCP for the transport layer depending on firmware and installer preference. Connection settings are part of the public integration context and are important for routing data reliably to Plaspy.

  • Devices may be configured to send data to d.plaspy.com or directly to 54.85.159.138.
  • The port used for Plaspy device traffic is 8888 and is the same for all devices supported by Plaspy.
  • The tracker can be set to use UDP or TCP on port 8888 depending on device support and configuration.
  • GPRS network reliability, SIM APN settings, and mobile coverage affect message delivery to the Plaspy endpoint.
  • Confirm that the tracker’s outbound data channel to the Plaspy endpoint is allowed by any local network firewall or SIM data plan restrictions.

Protocol Compatibility Notes​

  • Firmware revisions can change message timing, available fields, or optional features; always check the device firmware version when validating behavior.
  • Hardware revisions or regional variants may expose different inputs or alarm wiring for features like fuel cut off or ACC detection.
  • The choice of UDP versus TCP affects delivery semantics; installers should choose the transport that matches the device firmware capabilities and network conditions.
  • Some features such as remote control commands, remote listening, or advanced telematics may require specific firmware or configuration options.
  • Validate compatibility and supported features against official manufacturer documentation for the specific device batch or firmware.
  • Practical testing with the actual SIM and a controlled environment helps confirm that Plaspy successfully detects and ingests the device data.

Why Protocol Understanding Matters​

Understanding how the C790-Y communicates with Plaspy helps ensure a reliable installation, efficient data usage, and predictable alerting behavior. Being aware of the public integration points reduces time spent troubleshooting and improves the quality of telemetry available to operators.

  • Speeds initial setup by ensuring the device is pointed to the correct Plaspy endpoint and port.
  • Helps isolate connectivity issues that stem from APN, SIM, or mobile network problems rather than platform parsing.
  • Clarifies which vehicle inputs and alarms will be available inside Plaspy for rules and notifications.
  • Supports informed decisions about using UDP or TCP based on network reliability and expected message loss or latency.
  • Enables realistic testing and verification of features such as ACC detection, SOS events, and remote immobilization workflows.

Why Use Plaspy with This Protocol​

Using the GOTOP C790-Y with Plaspy gives organizations a practical combination of satellite positioning, GPRS telemetry, and event driven reporting for fleet visibility and security. The device’s ACC monitoring, SOS button, remote fuel cut off, and alarm reporting map directly to Plaspy workflows for geofence alerts, real time monitoring, and historical route review.

Plaspy’s automatic protocol detection and shared connection settings simplify deployment: device installers configure the C790-Y to report to d.plaspy.com or 54.85.159.138 on port 8888 (UDP or TCP as supported), and Plaspy ingests the telemetry without requiring manual protocol selection.
