Not able to access website via USB on amplifiers and control systems with GUI

This article is applicable to the following products:

Biamp PM4100, AMP-D225H & Impera Tango, Lima, Alfa II and Sierra II. Neets Preamplifier, Neets Amplifier 2:25, TanGo, LiMa, DelTa, AlFa II, and SieRRa II.

When connecting one of the above-mentioned products to your PC via USB, you have the option to access the web GUI, using Internet Explorer and entering the URL http://192.168.0.4 or http://neetsweb

If that functionality doesn't work on your machine it is probably due to the drivers not being installed correctly in Windows. We have seen issues on some PC's where you manually have to go to 'Device manager' in Windows to fix it. The way to identify if this error is present on your machine, is that you don't have the Neets Control System RNDIS device present under Network adaptors like in the below screenshot, when one of the above mentioned products is connected via USB.

Solution:

1. Make sure your USB device is connected to your PC.

2. In Device Manager go to "Ports" where you find your serial ports and Biamp/Neets devices. Here you will find more than one serial device, and typically close to each other like COM7 and COM8 or COM14 and COM15 like in the example below.

3. Now right-click on the device called "Serial USB-device" named COM14 in the above example and select "Update driver".

It will now discover and install it as a Biamp Control System RNDIS network adaptor instead, and you can now access the web GUI using the links above. 

We are looking into if we can improve the process with automatic Windows driver installation. 


NOTE: One thing that can be a bit confusing in this process is that the second "Serial USB-device" will not disappear from the "Ports" section when you unplug the USB device from your PC. So basically you won't suspect that this has something to do with the Biamp/Neets device. But that is the case.
