+=== Q3: How can I password protect Node-RED / My Node-RED is password protected ===
-Password protection of Node-Red is linked to the remote console. If a password is set for the remote console, this password is also used for securing Node-Red. The username is ''admin'', the password is the remote console password.
+__Venus OS v3.50 and later__
+For systems that have a security profile set (under Settings -> General -> Security Profile), the password protection is linked to the chosen security profile. The password that has been set for either security profile "weak" or "secured" is also used to access Node-RED, in combination with username ''admin''.
+__ Venus OS versions prior to v3.50__
+The Node-RED's password protection is tied to the remote console. If a password is set for the remote console, this password is also used for securing Node-Red. The username is ''admin'', the password is the remote console password.

 And restart Node-RED.
+=== Q11: Is there a way to have the context survive reboots? ===
+By default the context is stored in memory of the GX device only. If the GX device gets rebooted, the
+content of the memory gets reset and you loose the context information.
+In order to keep the context data, it is needed to [[https://nodered.org/docs/api/context/store/localfilesystem|store the context to disk]]. This can be achieved by creating (or adding to) a user configuration file ''/data/home/nodered/.node-red/settings-user.js'', containing:
+  module.exports = {
+    contextStorage: {
+      default: {
+        module: "localfilesystem",
+        config: {
+          flushInterval: 300 // Save context data every 5 minutes
+        }
+      }
+    }
+  }
+With the above settings, context files will get created periodically in ''/data/home/nodered/.nodered/context/''. In order not to wear out the flash too much, don't write too often.

 ==== 6.3 First use & configuring ====
-=== Step 1. Opening the dashboard ===
+Follow these steps to turn your GX into a NMEA to WiFi gateway within 5 minutes.
-Open a web browser, and go to the SignalK Dashboard by navigating to http://venus.local:3000.
+These instructions assume that your GX device has already been set-up with Venus OS Large, and Signal K is enabled.
+=== Step 1. Signal K Admin page ===
-Further documentation about that is ... (some link to signalk-node documentation?)
+Open a web browser, and go to the Signal K admin page by navigating to http://venus.local:3000.
-=== Step 2. Configure serial connections ===
+{{ :venus-os:img_2580.jpeg |}}
-Use this to, for example, configure a USB-connected NMEA0183 connection in SignalK. To do so, go to the dashboard (http://0.0.0.0:3000), and there to Server -> Connections.
+=== Step 2. Set the admin password ===
-Make sure to not add a connection using any of the built-in serial ports (/dev/ttyO0, /dev/ttyO2, /dev/ttyO4, /dev/ttyO5). These are the VE.Bus- and VE.Direct ports on the Venus GX, and it is not necessary to configure them in SignalK. Data from any devices there connected is already available in SignalK, by means of the "Victron Venus Plugin"; see Dashboard -> Server -> Plugin Config.
+Go to Security -> Users and create an admin user for Signal K and protect it with a secure password.
-Note that once configured in SignalK, for example a USB-serial port, that port is no longer normally available in Venus OS. For example, when plugging in a USB-GPS; and then adding a connection for its corresponding tty in the SignalK, makes for that GPS to be no longer be recognised and available in Venus OS.

-=== Step 3. Configure can-bus connections ===
+=== Step 3. Vessel information ===
-For the Venus GX, and Cerbo GX, SignalK comes pre-configured with a NMEA2000 listener for the VE.Can ports, its named "n2k-on-ve.can-socket", and uses the canboatjs. Here is how you can see the same in the Signal K Admin UI:
+Go to Settings and enter some basic information about your boat.
+{{ :venus-os:img_9926.png |}}
+=== Step 4. NMEA2000 Can-bus connection ===
+For NMEA2000 networks, its recommended to have all connected devices use isolated connections. Therefore, when connecting the an NMEA2000 network, we recommend using the Ekrano GX and the Cerbo MK2 GX. Connect to the port physically labelled “VE.Can 1”.
+Signal K is preconfigured to have its port operational for this.
+Here is how you can see the preconfigured connection in the Signal K Dashboard:

 For more information on CAN-busses, see chapter 6.4.
-=== Step 4. Adding Signalk Plugins or Webapps ===
+=== Step 5. Optional: Configure NMEA0183 serial connections ===
+Use this to, for example, configure a USB-connected NMEA0183 connection in SignalK. Go to Server -> Connections.
+Make sure to not add a connection using any of the built-in serial ports (/dev/ttyO0, /dev/ttyO2, /dev/ttyO4, /dev/ttyO5). These are the VE.Bus- and VE.Direct ports on the Venus GX, and it is not necessary to configure them in SignalK. Data from any devices there connected is already available in SignalK, via the "Victron Venus Plugin"; see Dashboard -> Server -> Plugin Config.
+Note that once configured in SignalK, for example a USB-serial port, that port is no longer normally available in Venus OS. For example, when plugging in a USB-GPS; and then adding a connection for its corresponding tty in the SignalK, makes for that GPS to be no longer be recognised and available in Venus OS.
+=== Step 6. Verify received data ===
+Go to the Databrowser to see the data now available to Signal K, and to tablets and nav. apps on   WiFi:
+{{ :venus-os:img_2578.png |}}
+=== Step 7. Configure your nav app ===
+Steps needed here will differ per app. The key required data is:
+  * Host/IP address: **venus.local**
+  * Protocol: **TCP**
+  * Port: **10110**
+=== Done! ===
+Now you should have all your data such as position from the boat’s GPS, speed, wind data, as well as AIS targets in your favourite nav app. Like here in Navionics:
