doorbell guard with 433.920 receiver

[giovannimarletta]

ciao everybody, I've found a doorbell that work on 433920 frequency.
this little receiver have a dip switch block with six switches on rear .
I'm searching to make it work it but I wonder if somebody can tell me how can convert the dip switchs position as binary or exadecimal code for an arduino test.
regards
