Arduino band decoder connections
-  switch JP1 jumper to programable arduino

 -  connect USB/UART interface for programing arduino mini board to SV1

 - upload the arduino code
 -  switch JP1 jumper to DB9 CAT

 -  power on JP2

 -  connect TRX (between male connectors)

If connect TRX CAT with PC logbook, do not connect TX wire from decoder (pin 3↔3). Decored will worked in sniff mode. -  signals on BCD
