How to Assemble and Install an AXISdapter

Step 6Wiring

Wiring
The important thing to remember about using an AXISdapter in an arcade stick is that you must be careful about which wires you setup as your common. On most common ground boards, there is a single wire that is sent to one pin of every microswitch direction and button. With an AXISdapter, the 'common' lines for your buttons and stick cannot all be tied together. Everything is grouped to be as easy as possible, but please take a moment to be sure of your wiring.

There are two main terminals on the AXISdapter, the longer terminals with 7 pins each. One terminal contains the four D-pad direction, L1, L2, and a common line for those inputs. The other 7 pin terminal has pins for the four face buttons(circle, square, etc.), R1, R2 and a common line for those inputs.

The smaller set of screw terminals is for the 'control' buttons, start, select, and the Playstation 'home' button. On the ShinJN version, there are two 'common' pins, one for the Playstation button, and the other for start and select. Despite the warning above, the start, select, and Playstation buttons do not require a specific common. They can be activated by the common from either of the 7 pin terminals. This makes wiring quite a bit easier as you will see soon.

First, let's wire up the the stick. If you are using a 5 pin connector, like a Seimitsu or Sanwa harness, then wiring is a cinch. Place the 'common' or 'ground' wire from the harness into the common screw terminal for the directions. This is marked 'COM_S' on the Toodles board, and marked 'GND (L)' on the ShinJN board.

The other four wires of the harness each correspond to a cardinal direction. Install the four wires into their matching screw terminal screw them down.

If you are using a stick with four separate microswitches for each direction, like a Sanwa JLW or Happ Competition stick, you need to run a wire from the common screw terminal for the directions (Marked 'COM_S' on the Toodles board, and marked 'GND (L)' on the ShinJN board) to one tab of each of the four microswitches. That's why it is called a 'common'. One wire from each microswitch should then go to the matching direction marked on the AXISdapter.

One nice thing about the AXISdapter is that the start, select, and Playstation buttons can be activated using either of the common lines. What this means is that you can run a single common wire to all of your buttons except for L1 and L2. If you are using only six main play buttons, you don't need or even want to use L1 or L2, so there is only one common wire for all buttons. Take a peek at my crude MSPaint wiring diagram to help illustrate what I mean.

If you intend to use an eight play button layout, you will need to wire up L1 and L2 as well. The common line for these two buttons can NOT be the one you used for the other buttons, or else your inputs will not work properly. It must be common line from that terminal block; the same common you used for the stick. The six play buttons from the other terminal block will have their common, and the last two button will use the other common.
