| + | ==== 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. |

| * Re-situate the pins from the FTDI header connector into the 2x4 connector.
