 +==== Change '​polarity'​ of the FTDI cable ====
 +
 +FTDI cables have standard '​inverted'​ TTL (zero is 3-5V and one is 0v) but the KH930E requires the opposite. Luckily its very easy to fix this by reprogramming the software.
 +
 +You will need a copy of [[http://​www.ftdichip.com/​Resources/​Utilities.htm|FTDI MProg ]] (windows only) and your FTDI cable. Plug in the FTDI cable into your windows computer and [[http://​www.ftdichip.com/​Drivers/​VCP.htm|install the driver that matches your computer best]]

 +[[http://​www.ladyada.net/​learn/​breakoutplus/​ftdifriend.html#​installing_ftdi_drivers|Please read our detailed tutorial on installing the driver here]] then come back when the driver is installed
 +
 +Now download [[http://​www.ftdichip.com/​Resources/​Utilities.htm|FTDI MProg]] and run the program
 +
 +==== Rewire the connector ====
 +
 +  * Re-situate the pins from the FTDI header connector into the 2x4 connector. [[http://​wiki.ladyada.net/​chumbyhackerboard/​serial|This chumby tutorial]] shows how to disconnect them from the original header.
