I'm looking to make a cable that would let my 5500 connect to a SparkFun Tri-Axis accelerometer.

Information on the accelerometer can be had here: http://www.sparkfun.com/commerce/product_i...products_id=248

I know that the Zaurus doesn't provide enough power over the serial connection, but I think there are solutions to it (either running some of the serial wires to a power source or directly powering the board).

The wiki page on making your own serial cable looks a tad old, and the section on using the Zaurus as a DTE remains unverified. I'm not too experienced with crafting my own serial cables, so any advice that people have would be appreciated. I currently have in my possession:

Two (2) Zaurus PDA serial port connectors
One (1) Serial cable I am willing to tear up
A soldering iron
Time and inclination :-)

Does anybody have any advice on the best way to go about doing this? What color cables go to what pins? Forgive me if these are newbie questions.

The second pinout LOOKS correct. (Basically, a Null Modem cable has all the Transmit and Recieve pins swapped, so the Serial port on each machine trasmits to the recieve pins on the other.)

a D-Plug is just the 9 pin connector for the other end. (D, because it's D-shaped. Duh!) There are all sorts of variants, in both Male and female, including High-Density (Like a monitor cable, with three rows not two.)

www.rapidonline.co.uk is a British seller that does them, and will show you the difference between M and F so you get the right one. They're usually pin-marked so you get the right ones. ^^

Thanks for the links! XD That's exactly what I needed.
