smartmicro Radar

The smartmicro radar is a forward-firing radar sensor used to detect and classify vehicles on roadways. When paired with TrafficXHub and SMATS' TMC software, it collects traffic count and speed data that can be monitored locally or accessed remotely through iNode.

This page covers everything you need to get up and running, from connecting the radar to your PC and configuring detection zones in TMC to mounting the hardware in the field. Whether you're setting up for the first time or re-wiring an existing deployment, you'll find step-by-step guidance for each part of the process.

PC Connection

There are two ways to connect the smartmicro radar to your PC: directly using the smartmicro Plug&Play cable, or through a TrafficXHub acting as a network bridge. The method you use will depend on your setup and whether you need remote access after deployment.

Direct Connection

The simplest setup connects the smartmicro Radar directly to a PC running TMC software using the smartmicro Plug&Play cable. Two interfaces are supported:

Ethernet Cable: Connect via standard Ethernet cable. No adapter required.

The image below shows the TMC Connections page configured for an Ethernet connection, found under Installation > Communication > Connections.

RS-485: Connect via RS-485 cable. A USB-to-RS-485 converter may be required depending on your PC.

The image below shows the same TMC Connections page configured for RS-485.

Connection via TrafficXHub

TrafficXHub acts as a data aggregator and router, bridging the radar's RS-485 interface to TCP/IP. This method supports both initial field setup and remote configuration via iNode after deployment.

Hardware setup: Connect TrafficXHub to the smartmicro radar JBox using the provided RS-485/12V cable. Once the hardware is connected, follow the steps below to obtain the device IP, configure the Radar plugin, and set up the TMC software.

Step 1: Obtain TrafficXHub IP Address

Connect TrafficXHub to your PC and open the web-based configuration page in your browser. The default static IP is 192.168.0.22.

Step 2: Configure the Radar Plugin

With the TrafficXHub IP address in hand, log in to configure the Radar plugin to route RS-485 data over TCP/IP.

1. Log in to the TrafficXHub configuration interface.
2. Navigate to Config > Scanner > Radar.
3. Set the Radar plugin to Config mode to enable RS-485-over-TCP routing.
4. Set the server port (e.g., 5001).
5. Restart the Radar plugin when prompted.

The image below shows the Radar plugin set to Config mode inside the TrafficXHub interface.

In this example, port 5001 is used as the server port. You will use this port along with the TrafficXHub IP address when configuring the radar in TMC.

Step 3: Configure TMC Software

With the Radar plugin configured, open TMC and connect it to the TrafficXHub using the IP address and port set in Step 2.

1. Open TMC and launch the Wizard.
2. Navigate to Installation > Communication > Connections.
3. Click + to add a Moxa server connector.
4. Select the target sensor from the available sensors list.

The image below shows the sensor selection screen in TMC after adding the Moxa server connector.

5. Enter the TrafficXHub IP address and port configured in Step 2.
6. Click Next and wait for the "Sensor Found" confirmation.

The image below shows what a successful connection looks like - you should see the "Sensor Found" message before proceeding.

You can now proceed to configure the radar.

Camera Live Feed (TRUGRD Stream)

You can access the camera feed for the smartmicro TRUGRD Stream model locally, or remotely through the iNode application (Radar Camera tab), using the following link:

Configuration

Once the radar is successfully connected to the TMC software, you will need to set up the lanes and zones, then enable the statistics module on the zones you want to gather data from.

Navigate to: Installation > Site Plan > Traffic Statistics

Configure the following:

• Zones/Lanes: Select the desired detection zones and lanes.
• Update Interval: Set the data refresh interval.
• Statistics Features Activation: Enable all desired feature flags.
• Object Classes: Select the vehicle/object classes to detect.

The images below show the Traffic Statistics page after a completed setup, giving you a reference for what a correctly configured page should look like. For complete instructions, refer to the smartmicro TMC Software Guide.

Length-Based Vehicle Classification

The radar classifies detected objects by length into the following vehicle classes:

Installation

This section covers the physical setup of the smartmicro radar system, what components are included, how they're wired together, and how to mount them in the field. Before proceeding, ensure the radar has been successfully connected and configured in TMC.

Components and Specifications

The SMATS radar detector system consists of:

• TrafficXHub: Data aggregator and router
• smartmicro forward-firing radar: Detection unit

TrafficXHub connects to the radar JBox via the RS-485/12V data/power cable provided by SMATS. The diagram below illustrates the full cabling setup between the two components and includes the recommended installation heights for both devices.

Radar orientation: You must install the radar facing the preceding and/or approaching traffic, as shown in the diagram. Optimal pitch, roll, and azimuth settings can be adjusted with guidance from SMATS staff, either on-site or remotely.

Wiring

If you need to re-wire the radar power/data cable, please follow the wiring diagram below when connecting TrafficXHub to the smartmicro JBox.

The diagram below shows the correct pin mapping for the data/power cable between TrafficXHub and the smartmicro JBox.

Mounting Brackets

Both TrafficXHub and the smartmicro radar include pole-mount brackets and clamps for installation. Please refer to the diagrams below for the recommended mounting heights and orientations.

• TrafficXHub: Pole-mount bracket included. The image below shows the TrafficXHub pole-mount bracket and how it attaches to the pole.

• smartmicro Radar: Pole-mount bracket included. The image below shows the smartmicro radar pole-mount bracket and clamp assembly.
