Does anybody have the instruction on how to build a Treo 600 9pin serial cable. I have the USB cable and want to convert it.

Thanks

If you have straight trough USB cable, you can't convert it to serial. If you still prefer USB, you must use USB to serial converter ( like with Prolific IC) and modified the pinout. If you want real serial cable, you need cable with max232 IC, you can buy it or make it for yourself. all diagram and pinout of treo are available on the net. just search.

BTW, what version of Treo you'd like to use with this cable ? GSM or CDMA ?
as far as I know, serial interface don't work with GSM version , only CDMA

Its a CDMA T600, the cable i need is to reed the seems and find the SPC code and the MSL code, so i can acces the nam programing. The SW only reads Com ports so i have a USB sync cable with the Sync botton and was wondering how to convert to a 9 pin Serial

well, the cable u mentioned above are original USB cable which don't have chip on it (straight through cable). as far as i know, you can not convert this cable to serial, you need USB to serial cable, you need to buy cable like Future dial cable and mod the pinout.

BTW : you can google it out, I had already read in some website that give you exact instruction to mod the cable and pinout, but i forgot the url.
