7.4 USB HID Ghosting
This function allows specific keyboard and mouse descriptors (device descriptions) to be permanently stored in the
CPU Unit. This permanent storage eliminates the need to register and deregister the keyboard and mouse on an
operating system each time there is a shared use of a source by two or more consoles within a KVM matrix.
The following table lists the keyboard commands for the configuration of USB HID ghosting:
Keyboard command
Function
Hot Key, h, w, Enter
Write the device descriptions of the input devices connected to the CON Unit into the
CPU Unit. Activates the emulation of these device descriptions in the CPU Unit.
Hot Key, h, e, Enter
Activate the emulation of already stored device descriptions in the CPU Unit.
Hot Key, h, d, Enter
Deactivate the emulation of active device descriptions in the CPU Unit. The input devices
connected to the CON Unit will be now passed transparently to the source.
Hot Key, h, r, Enter
Deactivate the emulation of active device descriptions in the CPU Unit. Deletes the
descriptions out of the CPU Unit. The input devices connected to the CON Unit will be
now passed transparently to the source.
NOTICE
When using a USB combo device as a USB HID input device, switching to a CPU Unit with activated USB HID
ghosting may cause limited functionality.
Keyboard commands are fixed to the position of the keys on the keyboard. Keyboard mapping tables may vary for
country-specific layouts.
E.g., press Hot Key, h, z, Enter on a French keyboard layout (AZERTY) instead of Hot Key, h, w, Enter to write
the device descriptions of the input devices connected to the CON Unit into the CPU Unit and to activate the
emulation of these device descriptions in the CPU Unit.
