Open-IO

A drop-in replacement for the EXT-IO. If you're not sure what the EXT-IO is, you probably don't need a replacement.

Required Parts:

• Arduino Mega 2560
• Max232 - To convert rs232 12v from BemaniPC/Python 2 to 5v for Arduino
• Hookup pins/wires
• 5v power source for Arduino

Connector & Cable Identification

To install the Open-IO, we first need to identify a few connectors inside of your DDR cabinet - Pad connectors, Neon Light connector, and Serial Communication connector.

Pad Connectors

There are 2 pad connectors (P1 - White; P2 - Orange) that each have 7 cables.

Pin Name	JP Cab Color	Kor Cab Color
Ground	Black	Black
FL1	Green	Blue
FL2	Blue	Green
FL3	Purple	Yellow
FL4	Grey	Orange
FL5	White	Red
TEST	Brown	Brown

Neon Connector

There is a Neon light connector (White) that has 2 cables (Red & Black).

Serial Communication Connector

Lastly we need to identify the serial communication cable from COM1 on your BemaniPC or Python2. This connector has 3 cables.

Pin Name	Color
GND	Black
RX	Grey
TX	Purple

Installation

Connect your Arduino using this pin-out:

Arduino Pin	Destination
2	P2 TEST
3	P2 FL5
4	P2 FL4
5	P2 FL3
6	P2 FL2
7	P2 FL1
8	P1 TEST
9	P1 FL5
10	P1 FL4
11	P1 FL3
12	P1 FL2
13	P1 FL1
16	RX on TTL side of Max232
17	TX on TTL side of Max232
22	Neon Red
5v	Max232 5v
GND	P1 GND
GND	P2 GND
GND	Neon GND
GND	Max232 GND

And connect your Max232 with this pin-out:

Note

All of these Max232 pins are on the RS232 side

If your Max232 has a db9 port, refer to the db9 pin column.

Max232 Pin	db9 Pin	Serial Data Connector Pin
RX	2	RX
TX	3	TX
GND	5	GND

You'll also need a 5v power source inside of the cabinet for your Arduino.
