 The DCDC boards receives messages over UART and microUSB. It sends out the messaages *just* over UART. The UART Baud rate is 57600.
 For a controlled communication, please use the perl script *./dcdc.pl*.
+
+If the command is supposed to switch the Switch (Loopback without jumper) then the dcdc.pl fails by checking the length because the answer can't copme back. For now, change the lince in the script (line 179: to "$num=1;").
