Controller Configurations

Serial controllers are connected to the computer COM ports; you simply select which port to connect to. No configuration is necessary for serial controllers.

PC-Bus controllers plug into a computer bus slot. They are set to I/O address 280 and IRQ 5 by default.

  • E-281-4035 IntelliTouch bus controller diagram. This controller requires jumper selection of both IRQ and I/O port address. The settings must match the Control Panel, Elo Touchscreen configuration.
