Navtelekom - СМАРТ S-2333A HIT

The SMART S-2333A HIT is a compact, earlier-generation GLONASS/GPS vehicle GPS tracker that remains a practical option for Plaspy compatible deployments where legacy hardware support is required. Although discontinued, the S-2333A HIT offers integrated high-sensitivity GLONASS/GPS and GSM antennas, a built-in rechargeable backup battery, and a flexible set of inputs and outputs that make it straightforward to add real-time tracking and telemetry to fleet management and anti-theft workflows.

Designed for simple installation and reliable operation in vehicle and asset tracking scenarios, this unit integrates standard telematics interfaces (RS-485, 1-Wire) and supports firmware and configuration management via the manufacturer's documentation and the NTC Configurator utility. Plaspy users can add the S-2333A HIT into monitoring platforms to capture location, sensor data and event-driven alerts using common telematics protocols over GSM.

Key Highlights

• Plaspy compatible: integrates with monitoring platforms that accept standard telematics protocols over GSM for real-time tracking and reporting.
• Integrated GLONASS/GPS and GSM antennas for compact, tidy installations without external antenna routing.
• Built-in 800 mAh rechargeable backup battery maintains tracking and event reporting during power interruptions.
• Multiple I/O options—two digital inputs, one analog input, one frequency/pulse input, and two configurable control outputs—enable telemetry, ignition/event detection, and remote control uses such as immobilizer support.
• RS-485 and 1-Wire interfaces allow connection of third-party sensors, temperature probes and other telematics peripherals for expanded telemetry and fuel monitoring possibilities.
• Discontinued but well-documented: manufacturer-provided product passport, user manual, connection schematics and published firmware facilitate integration and maintenance.
• Compact form factor and built-in antennas simplify installation for fleet vehicles and small assets where space and concealment are priorities.

How It Works with Plaspy

When deployed as a Plaspy compatible tracker, the SMART S-2333A HIT transmits GNSS position and telemetry over its 2G GSM modem to Plaspy’s ingestion endpoints using standard telematics protocols. Plaspy can consume location updates, discrete input events, analog readings and pulse/frequency counters to enable real-time tracking, route control, and event-driven alerts such as unauthorized movement or ignition status changes.

• Real-time location and telemetry updates: GLONASS/GPS fixes are sent over GSM for live position tracking and historical playback in Plaspy.
• Ignition and event monitoring: digital inputs can report ignition, door or alarm states to Plaspy for route and usage analytics.
• Fuel monitoring and counters: the analog and frequency/pulse inputs can be used to integrate fuel level sensors or flow/pulse meters when supported by attached peripherals.
• Remote immobilizer/control: the two configurable outputs can be employed for remote immobilizer or relay control when integrated into Plaspy alert workflows.
• External sensors via RS-485 and 1-Wire: temperature probes, environmental sensors and other telemetry devices can feed data through the tracker into Plaspy for expanded monitoring.

Technical Overview

Use Cases

• Fleet management: live vehicle tracking, route control and historical reporting for small to medium-sized fleets using Plaspy dashboards.
• Anti-theft and immobilization: event-driven alerts and remote disablement workflows using configurable outputs and Plaspy alerting.
• Telemetry and fuel monitoring: analog and pulse inputs can be integrated with fuel sensors and counters for consumption analysis and fuel theft detection.
• Environmental monitoring with external sensors: use RS-485 or 1-Wire connected temperature probes or other sensors to report telemetry to Plaspy.
• Legacy system integration: support for older vehicle fleets or assets where discontinued but documented hardware must remain in service.

Why Choose This Tracker with Plaspy

Choosing the SMART S-2333A HIT for a Plaspy compatible deployment provides a pragmatic path for integrating legacy GPS tracker hardware into modern monitoring workflows. Its built-in GLONASS/GPS and GSM antennas reduce installation complexity, and the internal 800 mAh backup battery improves resilience during power loss. The combination of digital, analog and pulse inputs plus RS-485 and 1-Wire gives integrators flexibility to capture ignition events, telemetry and fuel-related signals and feed them into Plaspy for real-time tracking, telemetry analysis and anti-theft controls.

Although the model is discontinued, manufacturer documentation, published firmware and the NTC Configurator utility support continued operation and maintenance. For fleets or asset owners maintaining mixed hardware environments, the S-2333A HIT can extend the service life of existing vehicles while providing core Plaspy-compatible capabilities such as real-time tracking, telemetry reporting and remote control via configurable outputs.
