Share NMEA 2000 instrument data with navigation software on a phone, tablet or laptop using the Actisense W2K-2. It combines a Wi-Fi gateway, voyage-data logging and Actisense-i network diagnostics in one IP67 housing.
App-ready data — Built-in conversion makes supported NMEA 2000 information available as NMEA 0183 sentences over Wi-Fi. Select a data format supported by the application; not every app accepts every protocol.
Flexible Wi-Fi layout — Access-point and client modes can operate simultaneously, allowing a suitable onboard wireless network to be used alongside the gateway. TCP and UDP are supported, with up to three data servers.
Voyage records — Fit a microSD card of up to 128 GB to record received network data for later analysis. The memory card is not included.
Network insight — Actisense-i provides diagnostic information including network voltage and connected-device status, helping identify installation problems.

FAQ
Does it need a separate power supply? — It takes its supply from the NMEA 2000 connection. Check the backbone power budget and correct termination.
Is the logging card included? — No. Install a compatible microSD card of up to 128 GB if recording is required.
Does it have a wired NMEA 0183 connection? — Its NMEA 0183 data is streamed over Wi-Fi. For a gateway with a wired ISO connection as well, consider the WGX-1-ISO.
Will every navigation app work automatically? — The application must support a compatible data format and network connection. Configure its address, port and protocol as described by the manufacturers.
