1.5 Use of USB Peripheral Devices

Panel PC 670/870 – Windows NT 4.0 with USB Stack

The operating system manufacturer does not support USB in the case of

Windows NT 4.0. In order to use the integrated mouse and the membrane

keyboard with the Windows NT 4.0 operating system, the Panel PC 670/870 has

been extended by the introduction of USB driver software. This extension makes

the internal keyboard and mouse operational.

Only external USB keyboards with integrated HUB, which fulfill the USB

specification 1.1, and standard USB mice (without any special additional

functionality such as scroll wheel) are approved for connection to the USB interface

at the front and the USB interface on the computer.

Notice

In order to be able to use the additional functions provided by the USB driver, the

menu item

USB Legacy Support must be set to Disabled in the BIOS.

Panel PC 670 – Windows 98/Windows 2000

The Panel PC 670 has a USB (Universal Serial Bus) interface integrated on the

front and back.

The USB interface is a flexible and easy way to use standard USB peripheral

components.

For example, either an external USB-capable keyboard or USB-capable mouse

can be connected to this port in additional to the keyboard and mouse already

integrated. If the USB-capable keyboard is also equipped with an external USB

port (USB hub), other USB-capable devices (e.g. mouse) can be connected to it.

Note

When using standard USB peripheral devices, note that their electromagnetic

interference immunity is often only sufficient for office environments. Such devices

are adequate for startup and maintenance purposes. However, components

suitable for an industrial environment must be used for the process operation.

The USB peripheral devices (e.g. keyboard, printer) are developed and marketed

by individual vendors. Support for the USB periphery devices is provided via the

respective product supplier. The terms of liability of the individual vendors or

suppliers apply.

The following types of USB peripheral devices can be distinguished:

• low power USB components:

max. 100 mA current; e.g. mouse, keyboard,

• high power USB components:

max. 500 mA current; e.g. hard disk, floppy drive etc.
