Hi,

I wanted to interface sony ericsson k700 phone to PIC using DRC11
(RS232) cable. But I was unable to find DRC11 cable in the market.

I have DCU11(USB) cable. I have schematic of DRC11 cable But not DCU11 cable. If you have some detail about DCU11 cable, please tell me and guide me to do this clearly.

Thanks............
 

according to the schemmatics that i found in thiss page
https://www.clubsonyericsson.com/foro/index.php?topic=23626.0

the #6 pin is RxD
the #7 pin is TxD
#9 + 3.3 v
#10 GND

for the rs232 connection i hope it works for you

Amila,
I mean have u tried what fiolin says by cutting off the USB head and take the TX and RX pns of the phone and connect to the PIC?Does it work cause I am stuck as i cant find a rs-232 cable for the phone.Thanks.
 

We should take RX, TX nad GND pin of the phone. then it works. If you want you can use just a connector of the USB data cable to connect above three pins.
Just cutting USB head and connecting RX,TX will not work.
regrds,
Amila
