1.3 Supported Peripherals

1.3.1 USB-HID Devices

The DKM Modular Extender will support most USB-HID devices, including the vast majority of keyboards and mice currently on the market. Many other kinds of HID devices such as bar-code scanners and touchscreens may also be compatible.

It is not possible to guarantee support for all available USB-HID devices. In certain cases, you may need custom firmware.

USB-HID (and other) devices that are not supported as standard will normally operate with our devices featuring transparent USB support.

NOTE: Concurrent operation of more than two USB-HID devices is not possible even if you use a USB hub.

1.3.2 USB 2.0 Devices

DKM Modular Extender models featuring a transparent USB 2.0 connection use Extreme USB Technology. This technology supports all types of USB 2.0 devices; however, we cannot guarantee compatibility with every device on the market. Please contact Black Box Technical Support at 724-746-5500 or info@blackbox.com if any issues are found.
