| - | ====== 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: | ||
| - | * [[http://www.adafruit.com/index.php?main_page=product_info&cPath=18&products_id=70&zenid=08edecd591934eebcc4993c01b0259d6|FTDI cable]] - you should be able to use a '3.3v' or '5v' cable. | ||
| - | * 2x4 connector part number [[http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=WM8036-ND|WM8036-ND on Digikey]] | ||
| - | |||
| - | You will need to make some minor mods to get the cable talking to your knitting machine. Follow the tutorials to get your knitting cable going | ||
| - | ==== 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 | ||

| - | |||
| - | Select **Scan...** from the menu | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogscan.gif |}} | ||
| - | |||
| - | The message window should say it found a cable | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogscanned.gif |}} | ||
| - | |||
| - | Now select **Read and Parse** to read in the cable programming | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogread.gif |}} | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogparsed.gif |}} | ||
| - | |||
| - | Click the buttons that say to **Invert TX and RX** | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogsignals.gif |}} | ||
| - | |||
| - | Here is the wierd thing, you have to **Save as...** the settings so just save it anywhere | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogsave.gif |}} | ||
| - | |||
| - | Now you can click the **Program** button (lightening bolt) | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogprog.gif |}} | ||
| - | |||
| - | The message window will say it programmed | ||
| - | |||
| - | {{ :tutorials:knittingmachine:mprogged.gif |}} | ||
| - | |||
| - | You're done! Quit Mprog | ||
| - | |||
| - | ==== Rewire the connector ==== | ||
| - | |||
| - | Next we need to rewire the FTDI cable to match the pinout of the knitter. The cable comes with a 1x5 connector, but we need a 2x4 connector | ||
| - | |||
| - | {{ http://www.ladyada.net/images/ybox2/propcablestart.jpg?500 |http://www.ladyada.net/images/ybox2/propcablestart.jpg}} | ||
| - | |||
| - | Use tweezers to lift up the black connector tabs | ||
| - | |||
| - | {{ http://www.ladyada.net/images/ybox2/propcableremovewire.jpg?500 |http://www.ladyada.net/images/ybox2/propcableremovewire.jpg}} | ||
| - | |||
| - | Then gently pull out the wire | ||
| - | |||
