12.1.3 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 bestimmten Fällen können solche Geräte mit spezieller Firmware betrieben werden.
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.
12.1.4 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.
12.1.5 USB 2.0 (transparent)
The extender module with transparent USB 2.0 interface supports almost all types of USB 2.0 devices.
USB 2.0 data transfer is supported with USB high speed (max. 480 Mbit/s) or USB-embedded (up to
36/50/100 Mbit/s), depending on the add-on module.
Each USB embedded port provides a maximum current of 500 mA (high power). When using a USB high
speed interface with 4 USB ports, respectively 2 connectors provide a maximum of 500 mA (high power)
and 2 connectors a maximum of 100 mA.
12.1.6 Mini-USB
The Mini-USB interface enables a customer specified communication with the extender module. The
firmware could also be updated using this interface.
