If GlobalReader Dashboard shows no data from the machine, go through the next steps.

   1. RED - Black Box is offline
   2. Yellow - no data from the machine or there is an ongoing interruption
   3. Green - machine is working

2. Machine works but no data on Dashboard

   1. If the machine is working but data doesn't appear on the graph, then check the cables of your sensor. In the case of a physical sensor make sure that the light on the sensor is blinking when it has to blink. It is also important to observe that it hasn't shifted, blocked, or damaged.

3. GlobalReader Black Box is offline

   1. If there is no LED light on on top of the BlackBox

      1. Make sure that there is current in the electrical socket - connect some other electrical device to it (for example: working lamp) or connect the Black Box to another plug where there is electric current.
      2. Make sure that the Black Box AC adapter works - connect the power adapter from the working GR device or an extra DC adapter (12V, 2A) to the Black Box and then check again.

   2. Cyan LED is blinking fast

      1. Some of the needed network ports are closed
         • ports 5683, 443, 80
         • connections allowed admin.globalreader.eu, port 80 and 443
         • connections allowed api.globalreader.eu, port 80 and 443
         • connections allowed cloud.globalreader.eu, port 5683, 80 and 443
         • connections allowed gate.globalreader.eu, port 80 and 443

   3. Green LED blinking fast shows that there is no WiFi/GSM connection - either WiFI credentials have not been saved to the Black Box or the Wifi router is not allowing the connection (for example: DHCP address is not being distributed).

      1. Check if the WiFi network is connectable from other device - for example mobile phone
      2. Check Wifi credentials and reconfigure Wifi credentials on the Black Box if needed - hotspot for Black Box is needed as guided Connecting Scoutbox and BlackBox
      3. Check if WiFi signal strength is greater than -65 dB, if not add an access point to the Wifi network.
      4. Check that WiFi network meets the criteria
         • Security - WPA2
         • 2.4 GHz frequency
           • Wifi BlackBox does not support 5GHz frequency
         • In firewall ports are opened
           • ports 5683, 443, 80
           • connections allowed admin.globalreader.eu, port 80 and 443
           • connections allowed api.globalreader.eu, port 80 and 443
           • connections allowed cloud.globalreader.eu, port 5683, 80 and 443
           • connections allowed gate.globalreader.eu, port 80 and 443

   4. Restart BlackBox by removing power from it for a few seconds and then putting it back

   5. Any other color on the Black Box, restart it and if no change contact [email protected]
