OKB Tehnoavtomatika - MTA-02 Protocol

This page describes the public protocol context for using the OKB Tehnoavtomatika MTA-02 GPS system with Plaspy. It focuses on how the MTA-02 communicates in general terms, what role the tracker reporting protocol plays in integration, and the common connection settings used to reach Plaspy servers. The MTA-02 is a flexible tracker that supports peripherals, multiple notification channels such as GPRS and SMS, and is suitable for vehicle, equipment, and asset tracking scenarios.

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 MTA-02 can vary depending on firmware version, hardware revision, and manufacturer implementation. This page provides practical, non-sensitive context to help with configuration and troubleshooting while encouraging verification against OKB Tehnoavtomatika documentation for firmware specific details.

Protocol Overview​

The tracker reporting protocol defines how the MTA-02 sends position, status, and peripheral data to a remote server and how remote commands or acknowledgements are exchanged when supported. For integration with Plaspy, the protocol's role is primarily to ensure the device can reliably identify itself and deliver usable telemetry over a supported transport.

  • Enables the MTA-02 to report GPS position, time, and status to a remote endpoint used by Plaspy
  • Carries event notifications such as ignition changes, sensor triggers, and peripheral inputs
  • Allows the device to include identifying information so Plaspy can associate data with the correct asset
  • Supports transmission over standard mobile data channels such as GPRS to reach the Plaspy endpoint
  • Provides the foundation for remote management workflows where the device and backend exchange state information

How Plaspy Detects the Protocol​

Plaspy receives incoming connections on a shared endpoint and determines how to interpret the incoming data so devices can be processed automatically. When an MTA-02 is configured to report to Plaspy, the platform will attempt to recognize the device protocol without requiring manual protocol selection in most cases.

  • Plaspy uses the same server domain and IP across supported devices, which helps streamline device setup
  • The Plaspy server domain is d.plaspy.com and the Plaspy server IP is 54.85.159.138
  • All devices in Plaspy use the same port, and Plaspy automatically detects the tracker protocol
  • Users typically only need to configure the tracker to point at the Plaspy endpoint and the platform will handle protocol detection
  • If a device is not behaving as expected, firmware differences or incorrect reporting settings are common causes to review

Transport and Connection Context​

Connection context covers the network transport the MTA-02 uses and the Plaspy endpoint information required for the device to deliver reports. The MTA-02 can use cellular data (GPRS) to reach Plaspy and may be set to use either UDP or TCP depending on the device configuration and firmware capability.

  • The device may be configured using UDP or TCP on port 8888
  • Plaspy listens on port 8888 for device traffic and this is the same port used by all supported devices
  • Devices may be configured to report to the domain d.plaspy.com or directly to the IP 54.85.159.138
  • Using the domain name allows standard DNS resolution and can simplify changes on the platform side
  • Network reliability, APN settings, and mobile operator behavior can affect how consistently the device reaches the Plaspy endpoint

Protocol Compatibility Notes​

  • Firmware version matters: protocol details and available features can change between firmware releases
  • Hardware revisions and optional peripherals installed on an MTA-02 may alter reported data fields and event behavior
  • The choice of transport (UDP vs TCP) can influence delivery characteristics and should match device capabilities
  • Manufacturer-side configuration options such as reporting intervals and event filters will affect the data seen in Plaspy
  • Always validate compatibility and supported features against current OKB Tehnoavtomatika documentation for the specific unit
  • In cases of unusual behavior, review device logs, configuration, and operator network notes before assuming a protocol parsing issue

Why Protocol Understanding Matters​

Understanding how the MTA-02 communicates with Plaspy helps ensure a smooth setup, faster troubleshooting, and predictable long term operation. Even though Plaspy automatically detects protocols and uses unified endpoints, knowledge of connection context and device behavior is valuable for administrators and integrators.

  • Proper device configuration reduces time to first fix and avoids common connectivity issues
  • Knowing transport options helps diagnose packet loss, retransmission, or intermittent reporting
  • Awareness of firmware and hardware differences prevents misinterpretation of missing or extra fields
  • Clear expectations for event reporting and sensor behavior improve alert tuning and operational workflows
  • Troubleshooting steps such as verifying APN, server address d.plaspy.com, or direct IP 54.85.159.138 are easier with protocol awareness

Why Use Plaspy with This Protocol​

Using the MTA-02 with Plaspy gives organizations a practical route to collect position and status data from vehicles, assets, and equipment while leveraging Plaspy's automatic protocol detection and uniform endpoint model. The MTA-02's support for peripherals and multiple notification channels pairs well with Plaspy's ability to ingest and surface telemetry for operations, security, and fleet management use cases.
