External Serial Ports

A National Semiconductor PC87309VLJ Super I/O controller is used to implement the two standard PC COM ports. These COM ports are compatible with the standard 16450 and 16550 architectures. They are labeled COM A and COM B and may be configured for any of the following ports:

COM1 (I/O address = 3F8-3FF, IRQ4) (COM A default)

COM2 (I/O address = 2F8-2FF, IRQ3) (COM B default)

COM3 (I/O address = 3E8-3EF, IRQ4)

The serial ports cannot share the interrupts with other devices.

USB Ports

A Universal Serial Bus (USB) controller is a host/hub controller and moves data between the main system memory and devices on the serial bus. The USB controller also includes the first level hub. This permits connection of two USB peripheral devices directly to the CPU chip set without an external hub. The port signals are accessible on two stacked USB connectors. If more external USB devices are required, an external hub can be connected to any one of these ports.

Floppy Disk Drive Port

The National Semiconductor PC87309VLJ super I/O controller provides a PC floppy disk port that supports one floppy disk drive. The floppy interface is a MiniD 20. The port includes +12 V and +5 V to power the disk drive, which will be current limited by Raychem Polyfuses to 1 A max. The connector for this port is unique to the Clean Screen II, so a Planar-supplied drive with custom cables should be used. Only pre-formatted diskettes should be used.

Optional Resistive Touch Screen Controller

Optional touch screen support is provided by an ELO TouchSystems E271-2210controller. If your Clean Screen has a touch screen, please refer to the Read Me file included on the touch screen driver disk. The E271-2210 controller board is mounted inside the display enclosure. Power is sourced inside the display. See Appendix D for additional touch screen information.

Hot Keys

control – alt – F1= brightness up.

control – alt – F2= brightness down.

Keyboard Interface

An external 87C42 keyboard controller will provide on AT-style keyboard port and support hot keys for adjusting the back-light inverter. The unit may be operated without a keyboard when appropriate pointing devices are installed.
