# Dancing Stage Fusion dedicated cabinet JAMMA edge wiring

The Dancing Stage Fusion dedicated cabinet has different wiring than
classic Dancing Stage/Dance Dance Revoluion Machines that are either based
on 573 analog/digital hardware or Python 2 hardware.

The cabinet connects to the main PCB using two JAMMA edge 28-pin connectors.

The following sub-sections provide full pinouts taken from a stock
Dancing Stage Fusion dedicated cabinet. `NC` denotes to "not connected".

## Pinout primary 28-pin connector

This 28-pin connector is actually following the JAMMA specification.

## Pinout secondary 28-pin connector

This 28-pin connector is the same as the primary connector but does not
follow the JAMMA pinout specification.

The follow hardware is connected on this connector:

* +5V power source
* Serial cable to EXT I/O
* Lights I/O cable to AMP box

## Lights I/O connector

Lights I/O connector that goes into the AMP box.
Pintout order: looking at the front of the connector, left to right:

```

## EXT I/O serial connector

Serial connector going to the EXT I/O board.
Pintout order: looking at the front of the connector, left to right:

## Adapter secondary JAMMA connector to "classic" DDR wiring

With the secondary JAMMA connector being propriatary to the Dancing
Stage Fusion cabinet, you need a "breakout" adapter that splices
the JAMMA connector into the following separate connectors:

* `EHR-5` connector to COM1 on the PCB for the EXTIO
* +5V supply, likely via a 2-pin connector that works with your
  cabinet's internal power infrastructure
* `XMP-11V` connector to PORT1 on the PCB for lights

Note: Bass lights, P1/P2 pad lights as well as sensor multiplexing
is handled by the EXTIO board.

### COM1 breakout

Pinout for the `EHR-5` connector breaking out of the JAMMA connector.

Pintout order for `EHR-5`: looking at the front of the connector,
left to right:

```text
|         |
|---------|
|1 2 3 4 5|
|---------|

1: GND (black)
2: NC
3: NC
4: RX (grey)
5: TX (purple)
```

Mapping for breakout cable:

```text
JAMMA top: 7     -> EHR-5: 5
JAMMA bottom: 7  -> EHR-5: 4
JAMMA bottom: 8  -> EHR-5: 1
```

### Lights connector breakout

Pinout for the `XMP-11V` connector breaking out of the JAMMA connector.

Pintout order for `XMP-11V`: looking at the front of the connector,
left to right:

```text
|          |--|         |
|-----------------------|
|1 2 3 4 5 6 7 8 9 10 11|

JAMMA top: 25     -> XMP-11V: 2
JAMMA top: 26     -> XMP-11V: 5
