Product Features & Benefits

The information collected by the DU700 and the smartphone app can be used to verify that a parking detector installation is working correctly.

The DU700 attaches to the front of any of the 7 Series parking detectors and acquires data from the detector via an optic link. The Nortech DU Diagnostics App supplied free for iOS or Android based smart devices is used to communicate with the DU700 and display the acquired data.

Data acquired from the detector is sent via the Bluetooth link to the App running on the smart device, which then displays information such as: loop excitation frequency, loop frequency drift, minimum and maximum level detection, and detector DIP switch configuration. The App is also able to generate a report that can be used to formally sign off a site or be sent for expert analysis where a fault is suspected.
