1.

 

Power your Sigma Tile with the Micro-USB cable.   Within about 15 seconds a Wi-Fi 
symbol will be displayed on the LED display, indicating that the Sigma Tile is 
searching for a network. 

    

2.

 

If you see the WIFI symbols: Congratulations!   You have completed this guide 
and built your own Sigma Tile. The next step will be to connect your Sigma Tile to 
a network and to further connect it with Kepware KepServerEX. You will learn 
how to do that in the Learn KepServerEX Using a Sigma Tile guide. 

3.

 

If you did not see the WIFI symbols, continue to the troubleshooting section. 
 

 

TROUBLESHOOTING: 

1.

 

If the LED Display shows a rainbow and stays on that image, try the following: 

o

 

Open the Sigma Tile Cover and try adjusting the SenseHat as the 
connection between the Raspberry Pi and the SenseHat may be 
improper with some possible Pins misalignments or false contacts 

o

 

Ensure that the Sense Hat is level with the Raspberry Pi and the 
SenseHat is fully placed on the lip of the Spacer.
