What the best place to install the Black Cat Radar?

For the best results, the Black Cat Radar Recorder should be installed:

    • Six to ten feet back from the road.

    • At least six feet above the ground.

    • At a 45 degree angle to the flow of traffic.

    • Where the far side lane is no greater than 50 feet away.

    • Where traffic is free flowing.


What do the lights on the front of the Black Cat Radar mean?

-Alarm Indicator – This light illuminates during boot-up. It also illuminates when a fault is detected.

-Run/Veh Indicator – This is normally ON, and flashes off when a vehicle is detected.

-Xfer A Indicator – Indicates a data transfer is taking place on the USB connection.

-Eng Indicator– If just the Eng light is on, this indicates the internal flash is being programmed. If both the Eng and Alarm lights are on, this indicates the internal flash is being erased.

-Link B Indicator – This indicates that the Black Cat is connected to a computer using the Mini USB port

Creating a Custom Length Scheme with JAMAR Radar Data
JAMAR Radar style counters will be shown in 13 groupings of speeds. Most customers find this default breakdown to be the best way to display their data. However, some choose to create custom length schemes for radar data. This process can be done by following the below steps:
From the main screen of TRAXPro, go up to ‘File’ in the top left corner and select ‘Scheme Editor’.
You will now see the TRAXPro Scheme Editor window.
Push the ‘OPEN, IMPORT or EXPORT a scheme’ button.
Scroll down to ‘Default Length Scheme’ and press the ‘Open’ button.
For this example, change the Description to ‘Small Medium Large Custom’.
Change the Number of Bins to 3.
Change the Bins in INCHES table to show row 1 as ‘From 1 To 71’, row 2 as ‘From 71 To 480’, row 3 as ‘From 481 To and greater’.
Press the ‘Save’ button.
Open your file and select ‘Length’ as your ‘Count Type’.
Then you will see, and select, your new scheme from the drop-down menu.
Process the data and you will now see your data being grouped into your three defined length classes.
If needed, you can right click on each column title to customize the group name: (For example, Small, Medium and Large).
