The WI-DG is a Wifi/Ethernet to USB bridge that is pre-configured for Plug&Play discovery and control over IP networks. The Wi-DG is a tiny adaptor that interfaces to the USB port of a miniDSP hardware unit and acts as a Wi-Fi to USB bridge. Supported miniDSP plugins transparently detect and communicate with the miniDSP via the Wi-DG, enabling control and configuration over the network. Normally, the computer running the appropriate miniDSP plugin is connected directly to the miniDSP hardware unit using a USB cable. With the Wi-DG, however, the computer connects using Wi-Fi in 2 possible modes of operations: Station mode or Access Point mode. Please check out the user manual for more details.
