Overview
The ITG-IO interface card is part of UltraCade Technologies’ series of JAMMA compatible PC
interface cards. For more information and a full list of current products, please go to
www.ultracade.com.
The ITG-IO provides a standard JAMMA interface for simple replacement of arcade motherboards
with a more reliable, configurable and upgradeable PC system.
The ITG-IO provides 32 I/Os (16 of each) including one optically decoupled output for complete
isolation. The remaining 15 outputs are designed for +12v operation and include surge protection
for electro-mechanical devices. +5v devices may be used; however, care is required as the surge
protection will be minimal.
Conversions are provided for PC video (0.7vpp) to Arcade video (5vpp) and PC audio (3.5mm jack)
to Arcade audio (two mono RCA jacks).

Power
The ITG-IO has two potential sources of power which must not be connected simultaneously. The
source of power depends on the application. Some JAMMA harnesses are self-powered, while
others require power to be supplied from the ITG-IO. In the former case, the ITG-IO is powered
from the JAMMA connector and the PC HDD (hard disk drive) connector must not be connected. In
the latter case, the ITG-IO is powered from a standard PC HDD connector, which then powers the
JAMMA harness. NOTE: be sure the JAMMA harness is not self-powered before connecting
the PC HDD power connector to the ITG-IO.
Another potential power source is the USB connector; however, no power from the USB connector
is used on the ITG-IO.
Irrespective of the method of connecting power, the ITG-IO is protected from the power source by
5A fuses on both the +12v and +5v lines. If power is connected using the PC HDD power
connector, then the ITG-IO and the JAMMA harness are independently protected from the power
source (J1); there are four fuses, for the +5v and the +12v lines to both the ITG-IO and the JAMMA
harness. If the JAMMA harness is the power source, the +5v and +12v lines each pass through 2
fuses to get to the ITG-IO proper.
The ITG-IO does not support the -5v JAMMA connection. If the JAMMA harness is the power
source, then the -5v signal is simply unused. However, if the PC HDD power connector is the
power source, then the -5v JAMMA connection is left unconnected, and hence not powered.
USB
Bringing up a USB design with the ITG-IO is made simple by the inclusion of shareware device
drivers for Windows and Linux along with the device driver source code and sample application
code. The only data that may need updating is the USB VendorID and ProductID in the device
driver. For backward compatibility with previously released products, these values are: VendorID
07C016 and ProductID 158416. It is recommended that a unique ProductID is requested from
UltraCade Technologies for each new product application.
With the device drivers installed, simply plug in the ITG-IO. The first time a USB device is plugged
into a Windows PC, the USB device will automatically “enumerate”. This process is basically the
USB device and the PC automatically configuring themselves.
The ITG-IO supports 16 inputs from the outside world (joystick, buttons, etc) and 16 outputs to the
outside world (lights, coin counter, etc). The 16 ITG-IO inputs are sent to the PC via a standard
“isochronous USB pipe on Endpoint 1”. The 16 ITG-IO outputs are set by a standard “Set Report”
command followed by the data on “Endpoint 0”. This is the standard USB configuration, and the
device driver may abstract away even this level of detail.
Once installed, the ITG-IO will send any changes monitored on the inputs at a minimum of 10ms
intervals. However, the changes to the inputs are monitored every 1ms, with all changes being
buffered so that no changes are missed, even if a button is pressed and released within the 10ms
reporting period. If no changes are detected in the 10ms reporting period, then the ITG-IO will not
waste time sending unchanged data. Output data sent to the ITG-IO is reflected on the output pins
of the board within 2ms of it being received.

Digital Outputs
An application sets the ITG-IO outputs using the USB Set Report command (BMRequestType 2116
and BMRequest 0916). All of the other fields in the command are ignored. The command is sent
down the control pipe (Endpoint 0) first, followed by the data packet. Only the first 2 bytes of the
data packet are used, and they are written directly to the outputs without parsing. The first byte is
written to microprocessor port 0, and the second byte to port 1. See the section on the connector
interface for a list of the assignment of the USB bits to the output connectors.
The ITG-IO supports 16 outputs. 15 outputs are decoupled ground enables using FET transistors.
The final output is completely isolated using an optocoupler. Setting an output simply enables the
corresponding circuit, either to ground or optically. Conversely, clearing the output simply disables
the circuit, either to ground or optically.
When connecting a device, connect the positive terminal to the relevant voltage supply, and the
negative (or ground) terminal to the relevant output pin on the ITG-IO. Enabling that output will
enable the circuit, and therefore the device.
Decoupling with FETs enables the only limitation on the current draw to be from the power supply
itself (the FETs used have maximum ratings of 1.6 amps continuous and 10 amp pulse). In
addition, a +12v surge protector is included as part of each output; this enables the safe use of +12v
electro-mechanical devices. NOTE: the surge protector has a lesser effect on +5v devices.
The isolated output is sent in the last bit of the second USB byte. This is routed out of
microprocessor port 1.7 to an optocoupler. Using an optocoupler means that the current is
completely isolated from the ITG-IO power supply.
The optocoupler used is low-power, and has the following ratings:
• Maximum current of 80mA continuous or 3 amp pulses
• Maximum voltage of +30v forward or +3v reverse
• Forward voltage drop of 1.2v

Video
The ITG-IO accepts video input from either a DB25 (standard PC VGA video connector) or a 6-pin
156mil Molex (standard arcade video connector). Video is then produced on the relevant pins of the
JAMMA connector.
The ITG-IO does not do any scaling of the video. The video must already be in a resolution
compatible with the target monitor. If rescaling is required, the video signal can be routed through
an UltraCade uVC video converter (see www.ultracade.com).
Two forms of video processing are performed by the ITG-IO. The 0.7vpp PC video signal is
amplified to the 5vpp arcade levels, and the synchronization method is ensured to be in composite
format.
All current main stream monitors use +5v synchronization signals, however, the red, green and blue
signals are different voltages in VGA monitors and arcade monitors. Only the 0.7vpp RGB signals
produced by a PC need to be amplified to 5vpp. Therefore the video arriving from the PC video
connector (J3) is amplified, whereas the video arriving from the arcade video connector (J2) is not
amplified.
Synchronization signals used can vary. Most arcade monitors support both composite and separate
horizontal and vertical synchronization signals. However, the JAMMA connector requires just the
composite synchronization signal. The ITG-IO therefore combines separate synchronization
signals, from either the PC video input connector (J3) or the arcade video connector (J2), into a
composite signal. If the input video signal is already in composite format, the signal is unchanged.
Details on the JAMMA interface, including which pins are used for the video output, can be found in
the section entitled “JAMMA Interface”.

JAMMA Interface
The JAMMA interface is the standard interface for arcade motherboards. To simplify the
replacement of single game non-upgradeable arcade machines with PC based systems, the ITG-IO
allows the old motherboard to simply be unplugged and the PC plugged in. All the old controls will
flow through the same JAMMA interface and be converted by the ITG-IO into USB packets.
The table below shows the standard use for each of the JAMMA pins, and how it is attached to the
ITG-IO. For example, the video green pin on JAMMA pin S12 is produced from the video green
input; player 1’s start button on JAMMA pin C17 is sent to the PC via USB in the fifth bit of the
second byte. The only ITG-IO output routed through the JAMMA connector is the primary coin
counter, which is written from the PC via USB in the seventh bit of the second output byte.

Connector Interface
All of the inputs into the ITG-IO are through the JAMMA connector. Therefore, all of the additional
connectors are used for outputs. When a USB packet is sent by the PC to the ITG-IO, the two data
bytes are written directly to the microprocessor’s outputs. Setting an output bit enables the circuit to
ground, while clearing the bit disables the circuit ground.
The exception is connector J4, which is the isolated output. The collector and emitter are
connected directly to the optocoupler. Enabling and disabling this circuit is done through USB 1.7
(eighth bit of the second byte).
In the table below, the two output bytes are numbered 0 and 1, while the eight bits are numbered 0
through 7.
