Thanks for the pic embed R. My bad!
wvmarle:
1 - It's defo RS23, and voltage is 5v so i'll need the TTL converter. No biggie, just another thing on the list!
2 - Serial data protocol is:
Baudrate: 9600/no parity/no handshaking
Bits: 8
Stopbit: 1
3 - I'll have a look into it.
Thanks for the response!
