OKB Tehnoavtomatika - MTA-03 Protocol

This page describes the public protocol context for using the OKB Tehnoavtomatika MTA-03 tracker with Plaspy. It focuses on how the device communicates with Plaspy in general terms and what you should consider when configuring reporting and connectivity. The goal is to provide clear, non sensitive information about the communication role of the tracker and how it integrates with the Plaspy platform.

Plaspy uses shared connection settings for all supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior for the MTA-03 can vary with firmware, hardware revision, and manufacturer implementation, so use this guidance together with the device documentation and any firmware release notes from OKB Tehnoavtomatika.

Protocol Overview​

The protocol for the MTA-03 governs how the device reports location, status, and alert information to a remote server and how it may receive certain remote commands or configuration triggers. For Plaspy, the protocol's primary role is to deliver timely and structured telemetry so the platform can display location, events, and health status to users and automated systems.

  • Enables the MTA-03 to send GPS position, movement, and status reports to a remote endpoint
  • Carries device identification so Plaspy can associate incoming messages with the correct asset
  • Transports alerting and event information such as alarms or input state changes for operational monitoring
  • Allows for different transport options so the tracker can use the most appropriate network method available
  • Supports periodic reporting and event driven messages to balance connectivity cost and timeliness

How Plaspy Detects the Protocol​

Plaspy receives device messages at a shared endpoint and automatically determines the tracker protocol based on the incoming connection and message content. In most cases a properly configured MTA-03 will begin reporting to Plaspy without manual protocol selection inside the platform.

  • Plaspy server domain for device reporting is d.plaspy.com
  • Plaspy server IP used for reporting is 54.85.159.138
  • Plaspy listens on port 8888 for tracker messages and uses the same port for all devices
  • Devices may be configured to use UDP or TCP on port 8888 depending on device capability
  • When a device sends data to the Plaspy endpoint, the platform identifies the protocol and processes messages automatically
  • Typically no manual protocol selection inside Plaspy is required if the device is pointed to the Plaspy endpoint

Transport and Connection Context​

Connection context covers the network transport and target server settings the MTA-03 uses to reach Plaspy. The MTA-03 supports internet reporting via GPRS and can also send SMS alerts to specified numbers; for Plaspy integration the important detail is the IP or DNS endpoint and transport mode you configure on the device.

  • The device may be configured to report to d.plaspy.com or directly to 54.85.159.138
  • Plaspy accepts both UDP and TCP connections on port 8888 depending on device configuration
  • Devices that support GPRS should be able to reach the Plaspy endpoint over the mobile data network
  • Confirm the APN and GPRS settings on the tracker so it can establish outbound data sessions
  • All devices in Plaspy use the same port so port selection on the server side is consistent across models

Protocol Compatibility Notes​

  • The MTA-03 has flexible configuration but behavior can differ by firmware version and hardware revision
  • Some features such as SMS fallback, alarm reporting, or satellite assisted functions may be device firmware dependent
  • Choose UDP or TCP transport based on the device configuration and network reliability in your deployment area
  • Always validate that the tracker is pointed to d.plaspy.com or 54.85.159.138 and is using port 8888 for reporting
  • For custom or advanced setups, confirm how the device encodes identification and event data in its reports
  • Check manufacturer notes when mixing MTA-03 units from different production batches or firmware generations

Why Protocol Understanding Matters​

Understanding the communication protocol of the MTA-03 helps ensure reliable reporting, smooth onboarding into Plaspy, and efficient troubleshooting when issues arise.

  • Helps verify that the device is correctly configured to reach the Plaspy endpoint
  • Makes it easier to interpret telemetry and event behavior seen in Plaspy when investigating anomalies
  • Supports informed choices about transport mode for tradeoffs between latency and network usage
  • Reduces setup time by aligning device settings with Plaspy expectations for connection and identification
  • Aids long term maintenance when updating firmware or replacing devices in a fleet

Why Use Plaspy with This Protocol​

Using the MTA-03 with Plaspy gives organizations a straightforward path to centralize location and status reporting for vehicles and stationary assets. Plaspy's platform is designed to accept reporting from a wide range of trackers, and the MTA-03's flexibility in configuration and notification methods makes it well suited for fleet and equipment monitoring where GPRS reporting and SMS alerts are useful.
