NVS - CH-5704 Protocol

This page provides a public protocol overview for using the NVS CH-5704 automobile terminal with Plaspy. It summarizes how the device can communicate with Plaspy for vehicle tracking and monitoring without exposing sensitive implementation details. The information here is focused on high level protocol context, transport choices, and practical compatibility considerations.

The NVS CH-5704 is a GNSS enabled terminal that supports GLONASS, GPS, GALILEO, and SBAS and uses GSM for data transmission. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, while exact protocol behavior can vary by firmware version, hardware revision, and the manufacturer implementation. For device specific commands and firmware notes consult the manufacturer documentation.

Protocol Overview​

At a high level the CH-5704 reporting protocol defines how the terminal packages navigation and status data and sends it to a remote server for processing. When integrated with Plaspy the protocol's role is to allow the device to identify itself, report position and telemetry, and receive optional server side commands or acknowledgements through standard network transport.

  • Enables the tracker to send GNSS position, time, and basic telemetry to a backend service
  • Carries device identity information so Plaspy can associate reports with the correct unit
  • Provides a channel for status updates such as ignition, battery, and movement indicators
  • Supports integration with fleet monitoring workflows and location based services
  • Operates over standard cellular data to reach Plaspy for real time monitoring

How Plaspy Detects the Protocol​

Plaspy receives incoming reports on a shared endpoint and uses automatic detection to handle many common tracker protocols. In most deployments you do not need to select a protocol manually inside Plaspy if the CH-5704 is configured to report to the Plaspy endpoint.

  • Plaspy listens on a single common port for all devices and automatically detects the tracker protocol
  • Devices configured to report to the Plaspy endpoint will be recognized as they send identifying information
  • Typical setup requires pointing the terminal to the Plaspy server address and using the correct transport
  • Manual protocol selection in the platform is rarely required when the device reports correctly

Transport and Connection Context​

Connection to Plaspy for the CH-5704 occurs over standard IP transport using the device cellular link. The terminal may be configured to send its reports via either UDP or TCP to the Plaspy endpoint on the uniform port used by all supported devices.

  • Plaspy server domain for device reporting is d.plaspy.com
  • Plaspy server IP address is 54.85.159.138
  • The shared transport port used by Plaspy devices is 8888
  • The CH-5704 may be configured to use UDP or TCP on port 8888 depending on device support and operator preference
  • All devices supported by Plaspy use the same port and Plaspy automatically detects the tracker protocol

Protocol Compatibility Notes​

  • Firmware versions and hardware revisions can change how the device formats reports and what fields are included
  • Manufacturer side configuration options may enable or disable specific telemetry or reporting intervals
  • Choice of UDP or TCP should match the device configuration and any network operator constraints
  • Verify the APN and cellular setup to ensure the terminal can reach the Plaspy endpoint
  • Confirm device identity settings match what Plaspy expects to avoid misattributed reports
  • Always validate compatibility against official manufacturer documentation when in doubt

Why Protocol Understanding Matters​

Understanding the CH-5704 communication protocol helps ensure reliable setup, easier troubleshooting, and predictable long term operation when used with Plaspy. Knowing how the device reports and what transport it uses reduces integration friction and supports effective fleet monitoring.

  • Speeds up initial configuration by aligning device reporting with Plaspy server settings
  • Makes troubleshooting simpler when position or telemetry reports do not appear in the platform
  • Helps choose the appropriate transport type and network configuration for your deployment
  • Assists in identifying firmware related differences that affect data fields or reporting cadence
  • Improves confidence in long term reliability and maintainability of the tracking solution

Why Use Plaspy with This Protocol​

Using the NVS CH-5704 with Plaspy gives organizations a practical way to convert GNSS and telemetry data into usable location intelligence. Plaspy's shared endpoint and automatic protocol detection simplify device onboarding so fleets can begin monitoring vehicles with minimal platform configuration.
