You cannot build that cable. Please look at the thread here: http://community.arubanetworks.com/t5/Aruba-Instan
You will have to purchase it.

Or, you can do as i did. I had to access the serial on an AP103 and could not get a hold of the propper console cable at the moment. I searched the Airheads community and with the info i could find i sucessfully managed to access the console using a cheap USB-TTL converter i had at home:
USE AT OWN RISK!
I do not guarantee this will work, if done wrong there is a risk that you permanently damage the console port of your AP/RAP!
First set the jumper on the USB-TTL converter to 3.3V! (5V TX signals might damage the console port on the AP/RAP, i have not tested 5V since 3.3V works.)
Secondly connect cables like this:
That's it. TTL-USB converters are not really rocket sience, and the Arduiono boom have made the converters really cheap and easy to find.

As Tamaz cited, you can use a USB TTL adapter, but you can also use a standard TTL-RS232 adapter as well.
It appears that the PIN out is also the same, VCC, RX, TX, and Ground.
VCC on the RAP-3 and the AP-205H appears to be 3.3V.
