2. Setup Instructions

Follow these steps to properly set up your GEHEN Pandora EX 2 Box Jamma board.

2.1 Connecting the Board

1. JAMMA Connection: Carefully insert the Jamma connector of the board into the Jamma harness of your arcade cabinet. Ensure proper alignment to avoid damaging the pins. Refer to the wiring diagram below for pin assignments.
2. Video Output: Connect your display monitor to either the HDMI port or the VGA port on the board using a compatible cable. Only one video output should be used at a time.

5. External Controllers (Optional): For additional players or specific game types, connect USB gamepads or PC joysticks to the USB ports on the board.

5. Troubleshooting

This section addresses common issues you might encounter with the GEHEN Pandora EX 2 Box.

5.1 No Power or Display

• Check Power Connection: Ensure the DC-12V power supply is securely connected to the board and plugged into a working power outlet. Verify the power supply is functioning correctly.
• Verify Video Cable: Confirm that the HDMI or VGA cable is securely connected to both the board and the display monitor. Try a different cable or display if possible.
• Input Source: Ensure your display monitor is set to the correct input source (HDMI or VGA).

5.2 Game Compatibility and Performance Issues

• Game Type Discrepancy: Some users have reported that the game library may contain a higher proportion of console-based games rather than traditional arcade titles. Review the game list to ensure it meets your expectations.
• Unplayable Games / Incorrect ROM Versions: If certain games are unplayable or exhibit issues, it may be due to incorrect ROM versions on the board's storage. Advanced users may attempt to replace ROMs with compatible versions, such as the MAME2003 v0.78 ROM SET. This typically involves accessing the SD card, editing the gamelist.XML file (located in plugins\assets), and replacing ROM files (located in games\data). This process requires technical knowledge and should be performed with caution.

5.3 Controller Input Problems

• JAMMA Harness: Inspect the Jamma harness connection for any loose or bent pins. Ensure the wiring matches the board's pinout.
• USB Controllers: If using external USB controllers, ensure they are properly connected to the USB ports. Test with a different controller if issues persist.
• Controller Mapping: Access the system settings menu to verify and adjust controller button mappings if inputs are not registering correctly.
