Metrici · LAN Controller

Loops. Barriers.
Scale. All Over
the Network.

The Metrici LAN Controller bridges your IP network to the physical world — collecting triggers from inductive loops, commanding barriers, and reading truck scales via RS-232. Custom firmware available for any project.

How It Works

Network Intelligence at the Gate

The LAN Controller sits between your physical infrastructure and your Metrici server — translating loop triggers and scale data into network commands, and turning LPR decisions into barrier actions.

⚡

Loop Detects Vehicle

An inductive loop embedded in the road detects a vehicle presence and sends a trigger signal. The LAN Controller receives up to 4 such inputs simultaneously.

📡

Trigger Sent to Metrici

The controller forwards the loop trigger over the network to the Metrici LPR server. Metrici uses it to fire a camera read at exactly the right moment.

🧠

LPR Decision Made

Metrici reads the plate, checks the database, and sends the access decision back to the LAN Controller over the network — all in under a second.

🚧

Barrier Opens

The controller activates the appropriate output relay, opening the barrier. For weighing stations, it also reads the scale weight via RS-232 and forwards it to Metrici.

Features

Everything in One Network Device

Based on Barix Barionet 50 with Metrici’s custom firmware — a proven industrial platform adapted for the full range of Metrici integrations.

🖧️

4 Inductive Loop Inputs

Receives trigger signals from up to 4 inductive loops in the road. Loops trigger LPR reads with precision timing, eliminating false detections.

🚧

4 Barrier Outputs

Commands up to 4 barriers or gates independently. Each output is individually controllable based on LPR decisions for that specific lane or entrance.

⚖️

RS-232 Scale Integration

Reads weight data from industrial truck scales and forwards it to Metrici’s weighing module. Full automation from vehicle arrival to weight record.

🌐

LAN / TCP-IP Control

Communicates with the Metrici server over standard Ethernet. No special cabling — works on any existing IP network infrastructure.

🧰

Modular Architecture

Operates standalone or as part of a distributed system with multiple units, web servers and control systems across a large site.

💻

Custom Firmware on Request

Metrici’s team can develop a customised firmware version containing functionalities specific to your project. Not a generic device.

📡

Core of Other Metrici Products

The LAN Controller is at the core of the Metrici Observer Radar and LED Display. The same hardware, different firmware for each role.

🏭

Wide Application Range

Proven in parking lots, weighing stations, toll gates, industrial parks, ports and any facility needing network-controlled physical access management.

Where to Use It

Any Gate. Any Scale. Any Site.

Wherever you need to connect loops, barriers and scales to a Metrici LPR system over a standard network.

🚗

LPR Parking with Loop Triggers

Inductive loops trigger the LPR camera precisely as a vehicle arrives. The LAN Controller forwards the trigger, receives the access decision, and opens the barrier — all automatically.

⚖️

Weighing Stations

Truck arrives, loop triggers LPR, weight is read from the scale over RS-232 and sent to Metrici alongside the plate — one complete, automated weighing record per transaction.

🛣️

Toll Stations

Multi-lane toll operations with up to 4 independent lanes per controller. Each loop/barrier pair operates independently under centralised Metrici management.

⛴️

Port & Terminal Gates

Container yards and port entry gates where multiple vehicle lanes need loop-triggered LPR and individual barrier control from a single network device.

🏢

Industrial & Logistics Parks

Distributed sites with multiple entry points. Each LAN Controller manages its local gates independently while connecting to a central Metrici server.

🟡

LED Display & Radar Integration

The same hardware platform is used inside the Metrici LED Display and Observer Radar products — giving partners a consistent, familiar device across their installation.

Custom Firmware for Any Project

The LAN Controller is not a fixed product — it is a programmable platform. Metrici’s team can develop a custom firmware version with any functionality your project requires. If your site has a non-standard scale protocol, a specific relay timing, or an unusual trigger sequence, Metrici will build it in.

The same hardware serves as the core of the Metrici Observer Radar and LED Display, with different firmware for each role. This means one familiar device, one vendor, multiple applications across your installation.

Custom I/O logic Non-standard scale protocols Specialised trigger sequences Observer Radar core LED Display core Distributed systems

⚖️

Weighing Station

Firmware reads the scale over RS-232, syncs with the loop trigger timing, and forwards weight + plate to Metrici in one atomic record.

🟡

LED Speed Display

The Observer Radar uses this hardware to drive the LED sign. Custom firmware translates radar speed data into display commands.

🏭

Industrial Automation

For complex sites, firmware can handle multi-step sequences — loop trigger, camera fire, weight read, barrier open — in a precise, configurable order.
