| − | The AYAB Interface comes with two plastic covers for the circuit board, as well as cable ties to hold them in place.
| |
| − |
| |
| − | These covers have laser-cut openings that expose only the connectors that you will need with the KH-930. There is a different cover for the front and back. The cover for the front has five openings for the connectors as well as a window for the name of the board, and the back side has openings for the power and USB ports.
| |
| − |
| |
| − | Fit the two covers into place, loosely attach them to the board with the cable ties, and trim the loose ends of the cable ties. The covers will not sit flat against the circuit board, but instead rest above the various connectors that you are not using on the KH-930.

| − | This is the Brother KH-930 knitting machine. Remove the two screws on top of the machine that hold the rightmost part of the top cover in place.

| − | Now, let's attach the first connector to the new AYAB interface. Hold the board as shown here, such that the majority of the exposed connectors are on the left. Identify the one small cable on the knitting machine that is on the right hand side, close to the main switch on the top of the machine. This is a small, three-wire cable, and it connects to the small, three-pin connector on the right hand side of the AYAB Interface board.
| |
| − |
| |
| − | Press the connector into place; it will only go in one way, and it should go in easily and click into place.

| |
| − | Next, add the other connectors. Start by adding the largest connector on the left hand side of the board and work towards the smallest. There are four connectors, each with a differently-sized plug.

| |
| − | Here is how the board should look once all of the connectors have been added. Note that the large power cable should be left disconnected, and as out of the way as possible.

| |

| |
| − | This completes the installation procedure. It is worth noting that this procedure is fully reversible-- if you wish, you can remove the AYAB Interface and connect all of the original cables back to their labeled locations on the original controller board.

| |
| − | Once the board is fully connected to the knitting machine, it is time to attach power and USB.
| |
| − |
| |
| − |
| |
| − | The ideal order of operation is as follows:
| |
| − | :# Plug the power jack of the included 9 V power supply to the receptacle on the back (top) side of the AYAB Interface.
| |
| − | :# Attach the micro-USB cable to the receptacle on the back (top) side of the AYAB Interface.
| |
| − | :# Plug in the power supply (or, if on a switched power strip, turn it on).
| |
| − | :# Plug the USB port into your computer.
| |
| − |
| |
| − |
| |
| − | An important note is that the AYAB interface completely replaces the original power supply. Whether or not the original power supply on your machine worked, do not separately plug it into power while using the AYAB Interface, or indeed, any time that the cover is open. '''Leave the original power cord disconnected!'''
