+==== Change 'polarity' of the FTDI cable ====
-The FTDI chip in the cable needs to be reprogrammed and the header rewired to fit the knitting machine's serial port.
+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]]

+==== Rewire the connector ====
-  * Reprogram your FTDI cable using [[http://www.ftdichip.com/Resources/Utilities.htm|FTDI MProg ]] (windows only) (need specific instructions on this still)
   * 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.
