Web Gauges Guide
The Web Gauges page (WG) of NMEA 2000 Wi-Fi Gateway, NMEA 2000 Wi-Fi Router, NMEA 0183 Wi-Fi Router and NMEA 0183 Wi-Fi Gateway allows real time viewing of vessel data using a web browser on a PC, laptop, tablet or smartphone and can replace instrument displays. You can open the WG using the link on the logon page of the device's administrative web site (no authorization is required) or, if you are logged in, using the "Web Gauges" menu item. No internet connection is required!
WG offers four customizable data pages. On mobile devices you can slide pages, or you can use the numeric buttons on the menu (at the bottom of the screen) to choose the active page. The BLK button on the left switches between day and night palettes. All the screenshots in this article were made on IPhone 7 if not specified otherwise.
See the video with Web Gauges in action. All basic operations are shown: opening of the WG page from administrative website, changing the layout of the data page, replacing and adding gauges and data bars, settings of data bars, preferred units settings, and viewing of NMEA logs from WG.
Data pages are pre-configured. The first page (see above) contains circular gauges for course/speed and AWA/AWS (apparent wind angle and speed), and text data bars with STW, heading, TWS and TWA data. The second page (see IPad Mini screenshot) is configured to view twin engines' data and contains circular tachometers and text data bars with engine temperature and fuel rate data. The third page contains data bars with position, time, log, sea and air temperature, barometric pressure and depth surface graph with current depth value. The fourth page is not configured and contains no gauges or data bars. You can change any page's layout and its sets of data bars.
On an IPhone, IPad and Android devices, the address bar and/or menu bar of a web browser can reduce the visible area and overlap with the WG menu in horizontal or vertical screen orientation. In this case, add WG to the Home Screen (see browser menu) and open it using the WG icon on the Home Screen. The page will then open in full screen mode without browser menus or address bars.
To customize the page, make it active and click the "SET" button in the WG menu. You can choose one of the predefined page layouts (rotate the screen to see how the selected layout looks with different screen orientations), and choose your preferred units (they are applied to gauges on all pages).
The layout contains from one to twelve placeholders. On the main screen, empty placeholders contain a cross in the middle. Tap the placeholder twice (on a mobile device) or click it with the mouse (on PC) to choose a gauge or data bar for this place. To exit from the "Edit mode", click on the "Exit" at the top of the data page, or click "SET" and set "Edit Gadgets" setting to "Off" (and you can turn the "Edit mode" on again here).
Gauges and data bars are grouped. For example, to add a TWD (True Wind Direction) circular gauge, switch groups with the "<" and ">" buttons in the menu until you find the "Wind Gauge" group. In the "Settings" section, switch to "Direction" and click the "Add" button.
Note that settings are saved in the browser storage associated with the address of the page. This allows having individual settings on each connected device. It also means that the settings are reset to default when the IP address of the device or the port of the administrative web server is changed.
To check what data are received by WG, click "SET" in the main menu and find the setting "Log NMEA" in the "OVERALL SETTINGS" section, then set it to on and click "Apply" to take effect. To view the log, click "SET" in the main menu and then click the "Logs" button to open the log window.
To rotate the data pages automatically, click "SET" in the main menu and find the "Rotate" settings in the "OVERALL SETTINGS" section and set the rotation to on.
