OKB Tehnoavtomatika - MTA-Glonass (ver.12-M RS-485)

The MTA-Glonass (ver.12-M RS-485) is a Plaspy compatible GPS tracker and vehicle monitoring terminal designed for fleet operators and service providers who need accurate positioning and wired sensor integration. Combining a 50-channel high-sensitivity GPS/GLONASS receiver with reliable GSM 900/1800 communications (DATA, GPRS and SMS), this unit provides real-time tracking, extensive telemetry and robust fuel monitoring via RS-485 connections.

Built for vehicles and telematics installations, the MTA-Glonass delivers fast technical readiness and low power draw while supporting multiple digital inputs, an ignition input, pulse/frequency fuel sensors and an RS-485 port for Omnicomm and similar fuel level sensors. Its compact IP30 enclosure and internal battery keep critical tracking and event logging running for hours after power loss — making it a practical choice for Plaspy-compatible fleet management, anti-theft and telemetry applications.

Key Highlights

• Plaspy compatible GPS tracker with GPS/GLONASS 50‑channel receiver for precise, reliable positioning and real-time tracking.
• GSM 900/1800 communications supporting DATA, GPRS and SMS for flexible server and subscriber reporting.
• RS-485 interface for direct integration with Omnicomm fuel level sensors and other intelligent wired peripherals for accurate fuel monitoring.
• Multiple configurable digital inputs and an ignition input for engine hours counting, sleep-mode control and event-driven telemetry.
• Internal rechargeable battery (up to 600 mAh) and non-volatile event memory (16,000–125,000 records depending on configuration) to preserve data during power loss.
• Low power consumption (active, idle and sleep modes documented) and fast readiness (technical readiness within 1 minute), ideal for continuous fleet management.
• Compact, lightweight form factor (≤90 × 65 × 30 mm, <200 g) suitable for discreet vehicle installation and asset tracking.

How It Works with Plaspy

When integrated with Plaspy, the MTA-Glonass acts as a source of location and wired-sensor telemetry. The unit reports position, timed events and sensor data over GPRS/DATA or SMS to Plaspy-compatible servers for real-time tracking, configurable alerts and historical reports. Its RS-485 port enables direct fuel-level telemetry to be forwarded into Plaspy dashboards or used in fuel monitoring rules.

• Real-time location and telemetry updates sent to Plaspy via GPRS/DATA or SMS for continuous visibility.
• Ignition input provides engine-on/engine-off status and supports engine hours counting for fleet management and maintenance planning.
• Fuel monitoring via RS-485 (Omnicomm and compatible sensors) and a pulse/frequency input for flow or pulse-based fuel sensors.
• Event logging and buffered non-volatile memory ensure no loss of critical records if connectivity is intermittent.
• Optional open-collector output can be used for remote control actions (for example, immobilizer or other vehicle control) when configured and supported by installation procedures.
• Although this terminal is built around wired RS-485 integration rather than Bluetooth sensors, it complements Plaspy deployments that also include BLE-enabled devices if BLE-capable trackers are used in parallel.

Technical Overview

Use Cases

• Fleet management: real-time tracking, ignition-based engine hours, and event logging for route optimization and maintenance planning.
• Fuel monitoring and loss detection: direct RS-485 connection to Omnicomm or similar sensors plus pulse/frequency input for accurate fuel telemetry and consumption analysis.
• Anti-theft and remote control: rapid location updates and an optional open-collector output that can be configured for immobilizer or other remote control functions during a security incident.
• Remote diagnostics and telemetry: buffered event logs and sensor data help capture critical diagnostics even with intermittent cellular coverage.
• Asset and equipment tracking: compact design and low power draw make it suitable for a wide range of vehicle and asset installations where wired sensors are required.

Why Choose This Tracker with Plaspy

The MTA-Glonass (ver.12-M RS-485) is a practical, Plaspy compatible GPS tracker for customers who prioritize reliable GNSS positioning together with sophisticated wired-sensor integration. Its RS-485 port and configurable inputs make it a natural choice for fleets that require accurate fuel monitoring, pulse-based sensors, and engine-hours telemetry. Low power consumption, an internal battery for continuity, and substantial non-volatile event storage reduce data loss risk and simplify fleet operations.

For fleet managers and service providers using Plaspy for centralized monitoring, this terminal brings dependable real-time tracking, event-driven alerts and the wired telemetry needed for fuel monitoring and remote diagnostics. Its compact form factor and straightforward I/O suite provide a robust foundation for anti-theft measures, immobilizer-type control workflows, and ongoing fleet optimization without sacrificing installation flexibility.
