Locator 690 (IDU-400) is a professional GNSS-enabled intelligent data unit built for demanding fleet management and commercial vehicle IoT. Designed for accurate GPS positioning, robust cellular telemetry and wide peripheral support, the Locator 690 is Net Domain Technologies compatible out of the box — enabling fast integration with Net Domain Technologies for real-time tracking, dispatching and operational analytics across mixed fleets.
Whether you need continuous location for anti-theft monitoring, per-second odometer reporting for fuel subsidy calculations, or MDVR telemetry for driver safety, the Locator 690 combines high-sensitivity GNSS, full-band LTE connectivity and multiple I/O to deliver the core data Net Domain Technologies needs to power dashboards, alerts and historical reports.
Key Highlights
- Net Domain Technologies compatible GPS tracker for seamless fleet management and real-time tracking via standard telemetry protocols.
- High-sensitivity multi-constellation GNSS (GPS + GLONASS, MT3333, -167 dBm) for fast, accurate position fixes.
- Full cellular coverage with 2G/3G/4G support and broad LTE band compatibility to ensure reliable data uplink and fallback.
- Comprehensive vehicle I/O (5 digital inputs, 2 analog, 2 temperature inputs, SOS, 4 digital outputs) for ignition, door and alarm telemetry integration.
- Onboard storage for ~30,000 records and automatic backfill to Net Domain Technologies when connectivity is restored — eliminates data gaps.
- Built-in G-sensor and tamper/power removal alerts provide anti-theft and collision event detection for rapid response.
- Remote firmware update and fault detection reduce downtime and simplify large-scale deployments.
How It Works with Net Domain Technologies
When paired with Net Domain Technologies, the Locator 690 streams position and vehicle telemetry using standard protocols (TCP/UDP/FTP/HTTP/SMS) so the platform can deliver live maps, geofence alerts, historical playback and custom reports. Net Domain Technologies ingests GNSS fixes, sensor inputs and event-driven alerts to provide consolidated fleet insights and automated notifications to dispatchers and managers.
- Real-time location and telemetry updates delivered to Net Domain Technologies for live tracking and route monitoring.
- Ignition and digital input events available to Net Domain Technologies for engine-on/off, door open/close, and alarm status reporting.
- Fuel monitoring support through optional fuel level sensor integration and per-second odometer/mileage reporting for accurate fuel subsidy and cost calculations.
- Anti-theft and remote response: geofence breaches, GNSS antenna disconnect/tamper and power removal alerts are forwarded to Net Domain Technologies for immediate operator action.
- Auxiliary sensor data (temperature inputs, SOS button, G-sensor events) appear in Net Domain Technologies dashboards and can trigger automation or escalation rules.

Why Choose This Tracker with Net Domain Technologies
Choosing the Locator 690 as a Net Domain Technologies compatible GPS tracker delivers practical benefits for operators who need reliable real-time tracking, robust telemetry and a long list of vehicle integrations. Its multi-band cellular modem and GNSS sensitivity reduce blind spots, while onboard storage and automatic backfill ensure no mission-critical data is lost during temporary outages. Multiple inputs and outputs make it straightforward to capture ignition, door, SOS and analog sensor signals — and digital outputs can be used to drive immobilizer relays or other control circuits where required.
For fleets focused on uptime and low maintenance, remote firmware update and fault detection minimize service visits and simplify scaling. When integrated with Net Domain Technologies, Locator 690 becomes a data-rich endpoint: live location, odometer-grade mileage for fuel monitoring, collision and tamper alerts, and customizable reports give fleet managers the visibility and control needed to reduce costs and improve safety. Whether you need telemetry for daily operations or regulatory-grade continuous monitoring, Locator 690 provides a reliable foundation for Net Domain Technologies-powered fleet intelligence.
Set Up 690 (IDU-400)
Use with a tracker
-
Set the Operator APN
CountryCarrierAPNinternet.comcel.com.coUserCOMCELWEBPasswordCOMCELWEB
- Check your tracker clock setup is set UTC-0 or GMT. (The most trackers come from the factory on UTC.)
- For most devices you should use IMEI (International Mobile Equipment Identity) number as unique identifier. However, some devices have vendor specific unique identifier, for example TK-103 devices use 11-digit identifier.
