EElink - TK419‑3 Features

This page provides a public feature overview for the EElink TK419‑3 and explains how its documented capabilities are used with Plaspy for real‑time tracking, fleet management, and telemetry. It summarizes practical device functions that Plaspy can surface, including multi‑constellation GNSS positioning, cellular connectivity, vehicle I/O, alarms, and sensor expandability.

Exact feature availability and behavior can vary by firmware version, hardware revision, installation method, and manufacturer implementation. Where specific functions are optional or depend on accessories, this page notes their presence in the public description and advises verifying the current device firmware and manufacturer documentation.

Feature Overview​

The TK419‑3 is a compact, vehicle‑focused tracker designed to deliver continuous GNSS positioning and event reporting to a fleet platform. Its practical value comes from reliable location updates, vehicle I/O awareness, expandability for accessories, and a rugged design suited for vehicle installs.

  • Real‑time vehicle tracking using multi‑constellation GNSS with AGPS to improve fix performance.
  • Wide area cellular connectivity with LTE Cat 1 plus GSM fallback to maintain telemetry in diverse coverage areas.
  • Vehicle I/O support such as ACC ignition detection and an optional relay for immobilizer or fuel/power cut‑off workflows.
  • Expandable inputs through GPIO and RS232 for accessory sensors and logging.
  • Comprehensive event and alarm reporting including collision/fall, vibration, speed alarms, SOS option, and geofence notifications.
  • Rugged compact enclosure with a wide operating voltage range and a built‑in emergency battery for reporting during power loss.

Core Features of EElink - TK419‑3​

  • LTE Cat 1 cellular connectivity with GSM fallback for consistent telemetry delivery.
  • Multi‑constellation GNSS support including GPS, GLONASS, BeiDou, and QZSS with AGPS assistance.
  • Vehicle I/O including ACC ignition detection and an optional relay for remote fuel or power cut‑off and immobilizer‑style control.
  • Expandable interfaces with GPIO expansion pins and an RS232 port for external sensors and accessories.
  • Event and alarm reporting such as collision/fall detection, vibration alerts, speed alarms with optional overspeed control, SOS button option, and geofencing.
  • Built‑in emergency battery to maintain reporting during primary power loss.
  • Rugged IP65 enclosure and compact form factor suitable for vehicle and asset installations.
  • Remote configuration and command support to adjust reporting behavior and enable or disable features over the air.

How These Features Work with Plaspy​

When configured to report to Plaspy, the TK419‑3 streams GNSS fixes, I/O states, and alarm events into the Plaspy platform so operators can monitor assets on maps, receive notifications, and run historical reports. Plaspy normalizes incoming data to present location, status, and event context in dashboards and alerts.

  • Real‑time GNSS position updates appear in Plaspy for live map visualization and route history.
  • ACC ignition state is reported to support start/stop analytics, duty logging, and usage tracking inside Plaspy.
  • Relay activation and immobilizer‑style commands can be issued from Plaspy where the device and installation support remote control.
  • Accessory telemetry from GPIO and RS232 devices (for example external sensors or access logs) is exposed in Plaspy reports when those inputs are enabled.
  • Event‑driven alerts such as collision/fall, vibration, geofence entry/exit, speed alarms, and SOS triggers are surfaced as configurable notifications.
  • Remote configuration changes and parameter updates sent from Plaspy allow operators to adjust reporting intervals and enable or disable specific features without onsite access.

Typical Use Cases​

  • Fleet management and route monitoring with ignition telemetry for dispatch and utilization analysis.
  • Anti‑theft protection and remote immobilization workflows using relay control and geofence alerts.
  • Driver safety monitoring and rapid incident notification via collision/fall and SOS reporting.
  • Temperature sensitive or condition monitored cargo tracking using external sensors connected to RS232 or GPIO.
  • Rental and mixed‑fleet vehicle tracking where small form factor and wide voltage support simplify installs.
  • Fuel monitoring and control workflows when external sensors and the optional relay are used to manage fuel or power.

Feature Availability Notes​

  • Some capabilities are optional or require accessories; verify whether your device includes the relay, SOS button, or sensor cabling before planning integrations.
  • Firmware differences and hardware revisions can change how events are reported or which parameters are configurable remotely.
  • Regional cellular variants and operator compatibility may affect connectivity; check device band support and local network availability.
  • Installation type and wiring affect available telemetry such as ACC detection or relay control; professional installation is recommended for vehicle control functions.
  • Always consult the manufacturer for the most current technical specifications and supported feature lists.

Why Use Plaspy with These Features​
