first, thanks for your answer.... but I still have the same problem...

I'm using only the module, and I'm working with atmega 16 at 9600 bps.
and I want to read only one byte for this reason the number that I sent was 192
and next I sent the number of the locality, but these numbers I sent in
hexadecimal... although the siteplayer don't response....
help me PLEASE...!!!
OR is possible send the numbers in decimal? another question the number should
send separated by intros or followed without spaces?
I'm doing this:
first send 20 nulls characters
next send the C0(hex)(192 decimal)it`s the number of the instruction to read
only one byte
and finally I send the number of the locality that is 05(hex)
later I wait for the siteplayer response but nothing happen..!!

Hi, I'm using also the siteplayer with an atmel microcontroller. You have to send character strings to the siteplayer. I don't know which programming software...

Hi, I'm using Bascom too, but I don't know how to synchronize the siteplayer with the atmega16, I'm using the command print chr(192), another question, it's...

... I usually send the "synchronizing" nulls just after my processor opens the serial connection to the SitePlayer. ... The answers comes back as 8-bit bytes...
