Automatic Input Selection - Example
The Concept
If there is no other source connected to the transmitter, but the MacBook, DP input will be automatically
switched to the optical output. If the MacBook and the PC are also connected to the transmitter, DVI-D input
will be switched to the optical output. If the Blu-ray player is connected on the HDMI input of the transmitter,
it will be switched to the optical output – independently of the presence of other video signals.
Settings
▪ Optical output
: Set the Autoselect to
Enabled
. Set Autoselect mode to Priority detect. The priorities are
the following (the lowest number means the highest priority):The priorities are the followings:
Source device Input port Priority
MacBook I1 (DP IN) 2
PC I4 (DVI-D IN) 1
Blu-ray player I2 (HDMI IN) 0
Priorities can be set in Lightware Device Controller software, see related settings in the Video Outputs and
Digital Audio Outputs sections.
3.10. USB KVM Function
HDMI-3D-OPT-TX210RAK, SW4-OPT-TX240RAK, and the HDMI-3D-OPT-RX250RA extenders support HID-
compliant (Human Interface Device) devices to transmit USB signal between the source and sink devices.
The transmitter connects to the controlled device (e.g. PC) and the controlling devices (e.g. computer
mouse, keyboard, touch panel) are connected to the receiver.
ATTENTION! Only HID-compliant devices are supported by the extenders. Non-HID devices (USB sticks,
webcams, etc) will not be working with the extenders.
USB KVM function can be used in two different modes:
Transparent
and
Composite mode
. The following

Transparent Mode
Transparent mode is a simple USB data transmission between the extenders. The same data is transmitted
on the TX side which is received on the RX side. The content of the transmitted packets are unknown to the
Lightware infrastructure so the data is not modified by any means during the transmission.
Key Features:
▪
Supports all HID-compliant devices.
▪
Driver software for all connected USB devices has to be installed on the controlled computer. When
you switch a crosspoint between two sources, the connected mouse and keyboard will be detected
as a new hardware in the operating system.
Composite Mode
The composite mode is an advanced data transmission method, recommended for most users. The devices
use their own data packets during data transmission. Thus, the content of the transmitted packets is known
to the Lightware infrastructure.
Key Features:
▪ Supports the following HID-compliant devices: computer mouse, keyboard built with 107 keys and/or
specific multimedia keys.
▪ No driver software is needed for the connected devices. The operating system uses the driver of the
extender to establish the connection for the USB devices.
INFO: You can find the related settings for Lightware Device Controller software in the USB KVM section.
USB KVM - Example 1
The Concept
The PC is connected to the transmitter with a USB cable. The signal is transmitted over the fiber optical
line from the receiver which is connected to the controller devices (to the keyboard and the mouse) to the
transmitter. The physical distance between the controled PC and the controller devices can be up to 2500
meters.
