Ultimarc J-PAC PC to JAMMA Board (Standard Version)

The J-PAC is a board which allows plug-in connection of a JAMMA arcade cabinet to a VGA card and USB port on a PC. It incorporates all the advanced features of the I-PAC with an on-board JAMMA connector. Includes USB and VGA Cables.

Features:

• NEW VERSION! Now has inputs fully protected against static discharge and reverse connection, now supports 3 extra JAMMA connections (Tilt, Service SW and Test)
• Now supports 12 volt coin doors.
• Fully programmable key code set. Stored even after power off.
• Self-Test LED gives an instant check of all your wiring. Can indicate which, if any, input has a problem.
• No separate power needed.
• Does not use a matrix - no ghost keys. All inputs are completely separate and generate their own interrupt - this is the fastest possible method.
• Does not use a scanning method which causes a variable delay.
• Either use 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 no extra buttons are needed on the cabinet. In programmable mode any input can be the shift key and all keys can be programmed with a shifted code.
• No special drivers needed. USB drivers are generic Windows.
• All control inputs which are part of a normal JAMMA standard are routed to an on-board JAMMA edge connector.
• Connector for VGA input from PC VGA card. Routes through to JAMMA edge connector for connection to the cabinet arcade monitor.
• On-board video amplifier boosts signal to standard arcade monitor levels. Uses high-bandwidth video amplifier chip.
• Custom microcontroller only allows sync signals to be sent to the monitor if they are in the correct range that the monitor is designed for. Avoids driving the monitor with a too-high horizontal sync rate which can damage some arcade monitors.
• Sync circuitry also converts separate horizontal and vertical syncs into composite sync. Can handle both positive and negative vertical sync.
• If required, can divide a 31Khz VGA signal in half so that it will display a stable picture on a 15Khz arcade monitor. Useful for checking boot-up progress and configuration (not for application use). Automatically stops dividing the signal when it detects a correct 15Khz rate is being send by the PC.
• JAMMA cabinet speaker routed to screw connectors for wiring to powered sound card or hacked PC speakers.
