Device configuration

At the first start-up, it is necessary to configure the device. The easiest way to configure Inveo devices is to use a Discoverer application. The program is available here. After installing and launching the application, all Inveo devices connected to the network will appear in the table. If the device has not been found, select another Interface or check the connection to the router.

If the devices have the Enable Remote Config service disabled, it is necessary to change the settings manually by changing the computer’s IP address. The precise device configuration instruction can be found in the manual.
