10.1 Interfaces
10.1.1 Mini-USB
The Mini-USB interface enables a customer specified communication with some add-on modules. The firmware could
also be updated using this interface.
10.1.2 USB HID
Our devices with USB HID interface support a maximum of two devices with USB HID protocol. Each USB HID port
provides a maximum current of 100 mA.
Keyboard
Compatible with most USB keyboards. Certain keyboards with additional functions may require custom firmware to
operate. Keyboards with an integral USB Hub (Mac keyboards e.g.) are also supported, however, a maximum of two
devices are supported.
Mouse
Compatible with most 2-button, 3-button and scroll mice.
Other USB HID Devices
The proprietary USB emulation supports certain other USB HID devices, such as specific touch screens, graphic
tablets, barcode scanners or special keyboards. However, support cannot be guaranteed for every USB HID device.
In certain cases, such devices can be operated with special firmware.
Extension
If it is required to extend the USB HID signals on CPU or console side (e.g., mounting requirement), the signals can
be extended either via a 3.0 m A-B cable (247-U2) or a 3.0 m USB A-A extension cable (436-USB20). The
compatibility to other extension cables cannot be guaranteed.
Only two USB HID devices are supported concurrently, such as keyboard and mouse or keyboard and touch
screen. A hub is allowed, but it does not increase the number of devices allowed.
To support other USB 'non-HID' devices, such as scanners, web cams or memory devices, use the USB 2.0
interfaces.
10.1.3 PS/2
Our devices with PS/2 interface support the use of a PS/2 keyboard and mouse.
Keyboard
Compatible with most PS/2 keyboards, even with various special keyboards. Certain keyboards with additional
functions can be run with special firmware.
Mouse
Compatible with most 2-button, 3-button and scroll mice.
