Ultimarc I-PAC 4 Keyboard Encoder USB Interface

Ultimarc I-PAC The world's most advanced PC interface for buttons and joysticks.
NEW I-PAC 4 Full Speed ​​USB 2.0. with upgradable Firmware and support for older PCs with PS/2 keyboard connection.

I-PAC is the ONLY keyboard encoder with up to 56 inputs, each with its own dedicated microprocessor pin.
No interaction or delays, essential for multi-button games like fighting games.

I-PAC is the ONLY keyboard encoder that emulates a USB keyboard (and PS/2) and yet breaks the 6-switch (plus Ctrl, Alt, Shift) limit set by USB simultaneously pressed that affects all USB keyboard devices.
This is because it has native USB support built in and does not rely on an add-on adapter.

I-PAC is the ONLY keyboard encoder that has a fully multi-processed interrupt-driven (so no performance loss) pass-through connector so that a connected keyboard (or a second encoder) is processed in PS/2 mode with full byte interleaving in place from on / off.

I-PAC is the ONLY keyboard encoder that can be programmed with or without host software. Even without special host software, the I-PAC can still display programming steps and current settings, so no "blind" work.

I-PAC is the ONLY device to have a switch function that allows ANY input to be assigned to a shifted secondary key code and the switch button can also have its own function, so no special extra button on the control panel.

I-PAC is the ONLY device to have a self-test LED that not only gives an instant visual check of your setup, but can also indicate which connection (if any) is causing a problem.

I-PAC retains its programming after shutdown. Look after! Not all keyboard encoders do this!

The ONLY thing the ipac can't do for you is order, so you have to do that yourself ;)

Characteristics:
Fully programmable code set. Saved even after shutdown unlike some other interfaces which lose all data when turned off.
Dual interface USB or keyboard - just swap the cable.
Optional pre-assembled LED harness with 3 panel mount LEDs emulating the keyboard Caps/Num/Scroll Lights. Many MAME games control the LEDs for coin-operated indicators or during the actual game.
All joystick/button connections can be easily made using a screw lab strip. Connections marked on the board.
Chunky 5mm screw connectors.
Self-test LED provides an instant check of all your wiring. Can indicate which input, if any, has a problem.
All ground related button inputs - no need to re-associate individual grounds to each button.
Lead plugs into keyboard connector on PC or USB port.
Can be programmed with special utilities (for DOS, Windows, Linux, MAC) or without special software, using an interactive method.
An unlimited number of keycode configurations can be saved and downloaded on the fly using host software. Withheld upon shutdown.
No separate power required.
Doesn't use a matrix - no ghost codes.
Does not use a scanning method that causes a variable delay. Each input has its own special connection to the built-in CPU.
Fast running interrupt driven software gives much better response than a standard keyboard controller. Key debounce uses a state method for each key. No delays between keys pressed at the same time. (essential for fighting games).
2 operating modes. Either uses standard MAME keys or you can program your own character set.
Shift functions. Holding "Start1" and pressing other buttons sends a range of codes for MAME functions, such as "escape", "Coin 1", "tab", "enter". This means that no additional buttons are required on the cabinet. In programmable mode, any input can be the shift key and all keys can be programmed with a shifted code.
Special Note to Windows MAME Users! Shift key functions allow you to select and launch games through the Windows interface without using the keyboard or mouse.
Connector for normal keyboard that can be used together with the controls if needed. No switching delays, means you can even play a game using the control panel and keyboard at the same time.
Supports selective up/down key repeat in PS/2 mode (repeat all keys in USB mode) for easy list scrolling with minimal CPU overhead and interface "clutter".
No special drivers needed. USB drivers are Windows generic. On many motherboards, USB works in DOS.
Fully compatible with all Apple Macs that have USB ports.
