Wiring Guide

This page will provide some basic, general wiring information that is common to most encoders as well as a few points that are specific to the KADE.
First a bit of advice: take your time and test your controls before committing to them.  This includes the layout of your buttons and drilling holes for them as well as understanding your wiring.

For most encoders, including the KADE miniArcade, the basic idea of wiring arcade based controls is running a common ground as well as a specific signal wire to a series of momentary switches that are operated by buttons and joysticks.  Most arcade controls use a micro-switch similar to the one shown below (in various colors). Note that some micro-switches have only 2 terminals (COM and NO).

In the picture below, the common wire is connected to the KADE ground.  You can use a daisy chain like the image or run individual wires from the Ground to each button.  The red button is wired to pin B1, blue to B2, and green to B3.  If your KADE is programmed with the default MAME configuration, the red button would activate P1 Button 5.  If you KADE is programmed with the default XBOX 1 configuration, the red button would activate A button.

There are a variety of opinons on the size and type of wires to use.  We like 20 AWG stranded coper wire.  Thicker wire is OK but we don’t recommend using anything smaller than 22AWG (larger number = smaller wire).

We suggest that you print out the mapping sheet in the KADE loader and use it at a reference when wiring.

 

Specific to KADE miniArcade

  • There are two grounds on the KADE miniArcade and either can be used.  We include 2 grounds for convenience.
  • The HWB is used to activate shift functions that you have programmed. HWB is controlled in the same way as the other pins, by wiring an arcade button (via micro-switch) to HWB and ground pins on the KADE.
  • The V+ pin provides +5V power to external devices. +5V peripherals and LEDS can be powered by connecting them to +V and Ground pins on the KADE.

Wiring Example

We are particularly impressed with the wiring of this control panel made by floriske.nl
Floris has documented his “evo XR cade” build on the BYOAC forum

First,  the ground harness is wired.
