I/O Communication
Each I/O board communicates to the PC through an USB to serial adaptor. If these adaptors are replaced or moved to a different USB port the configuration of their port address can change. This will cause the game to loose communication to that I/O board. The proper configuration for I/O board 1 is port 1 and I/O board 2 is port 2. If the game has trouble communicating to a USB port, the game will flash all Zombie arms yellow and sound the tilt alarm. Once communication is restored, the game will stop tilting.
To confirm or change the port settings it is recommended to disconnect one of the two I/O boards to ensure you are changing the correct I/O board.
