Compatibility

We support all displays that use the HX & HXE SIGN PROTOCOL v4.2.

The main difference between compatible displays is the physical size and how many characters can be displayed at one time.

While the displays usually support both a Serial and Ethernet connection, we recommend using the Ethernet connection for maximum stability.

For example, one popular choice for ANPR matrix displays is Spectra Displays. Please ensure the appropriate HX/HXE version of the display is purchased (the CPower versions are not compatible).

Note: TetherX are not affiliated with Spectra.

Setting Up in TetherX

  1. In TetherX, open Admin > Cameras > Edit Camera > Switch to the Advanced Tab

  2. Under ANPR Camera settings, tick the ANPR LED Matrix display tick-box and press Update:

3. Open Admin > TetherBoxes > Edit the relevant TetherBox > LED Matrix Display tab

4. Tick the "Enable LED matrix display" tick-box and fill in the form, for example:
​

5. The Matrix Display will show the license plate for the configured number of seconds, before switching to the default messages

Limitations

If you require something that is not currently offered by this feature, please let us know and we may be able to add it. Please note there may be additional costs for development or integration.

Some currently limitations include:

  1. You can only connect a single Matrix Display per TetherBox at present

  2. Only HX & HXE SIGN PROTOCOL v4.2 is supported.
    ​Note: Some manufacturers may have versions of the same display with and without the HX/HXD protocol support.

Example Installation

In this example of a live TetherX installation, it is configured to:

  1. Show "ANPR IN USE" as the default massage.

  2. When the camera detects a license plate, it shows the plate for 20 seconds or until the next car is detected.

  3. After the configured delay, it shows the "IMAGES RECORDED" message before going back to the default message.
