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
