-===== Watchdog ===== +===== Logic Controller Configuration ===== 
-The watchdog of the Strato Pi has to be configured for our use. First the firmware has to be updated to 3.5. Then we can connect to the serial interface. +Configuration of the StratoPi logic controller is performed through a 1200 baud, 8N1 UART connection at the following pins (5V if board is not connected to RPI)
  
 ^ USBUART      ^ Stratopi       ^ Corresponding pin on RPI          ^ ^ USBUART      ^ Stratopi       ^ Corresponding pin on RPI          ^

 +Pin counting begins with the pin closest to the screw terminals as 1.
  
-Where counting begins with the pin closest to the screw terminals as 1+This configuration assumes FW 3.5 on the logic controller.

 +==== Watchdog ==== 
 +  * ''XWED'' Set the watchdog enable mode to disabled (Badly named, in this mode, it's enabled by setting WatchdogEnable gpio pin from the RPI). 
 +  * ''XWH00005'' Set timeout to 5 sec. 
 +  * ''XWW00001'' Set the watchdog forced shutdown timeout to 1sec(min). 
 +  * ''XCCS''  Make configuration permanent.
