 ===== Make your own cable =====
 The kh930e is designed to work with a Tandy PDD1 floppy drive. We don't need it! Make your own cable to communicate between your computer and the machine. You will need:
-  * Inverted [[http://www.adafruit.com/index.php?main_page=product_info&cPath=18&products_id=70&zenid=08edecd591934eebcc4993c01b0259d6|FTDI cable]] reprogrammed with [[http://www.ftdichip.com/Resources/Utilities.htm|FTDI MProg ]] (windows only)
+  * [[http://www.adafruit.com/index.php?main_page=product_info&cPath=18&products_id=70&zenid=08edecd591934eebcc4993c01b0259d6|FTDI cable]]
   * 2x4 connector part number [[http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=WM8036-ND|WM8036-ND on Digikey]]
+==== 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.
 ===== Python code =====
   * Available on [[http://github.com/adafruit/knitting_machine|github]]
   * Based on [[http://www.antitronics.com/wiki/index.php?title=Electroknit_Technical_Information|Steve Conklin's knitting machine code]]
+  * Includes scripts for emulating the floppy drive, previewing patterns, and converting images to new patterns.
