USB Modes
Two channels are used for the USB communication between the extenders. Channel A1 is always transparent
and one USB HID device is always operable. The other channel’s state can be set which determines the
current USB mode.
Transparent USB Mode
Both channels are available for USB HID devices connected to the receiver. Default setting is transparent
USB mode which means both USB HID devices connected to the receiver are transparently transmitted to
the source computer.
USB channels in Transparent mode
Configuration USB Mode
Configuration USB mode is an option where the USB settings of the extenders can be configured by using
the Lightware Device Controller. One channel (A1) is available for a USB HID device, the other channel (A2)
is reserved for communication.

INFO:
The USB mode has an effect only on the state of the transmitter. Receiver is always in configuration
mode. Setting the USB mode on the receiver effects only the transmitter.
3.6.1.
Changing the USB Mode
The USB mode can be changed in the transmitter or in the receiver but in latter case make sure that the
extenders are linked by the fiber cables.
ATTENTION!
If the USB mode is changed in the receiver when the extenders are not connected by fiber
cable, the setting is store in the receiver and the USB mode will be changed after reconnecting.
Step 1.
Power ON the extender(s) and locate the hidden function button on the bottom side.
Step 2.
Press and keep pressed the button by a thin tool (e.g. paper clip)
for about two seconds. Release the button not more than five
seconds.
Step 3.
The current USB mode is visible on the front panel.
ATTENTION!
When the configuration mode is active, only one USB HID
device can be used: the one that was connected to the receiver at first.
INFO:
Default setting (transparent mode) is restored when the device
is powered on.
3.7. HDCP Setting
When a non-HDCP compatible sink is connected to the receiver, the source can be forced to output non-
encrypted signal if the content is not protected. For more information about the HDCP management, see the
section.
HDCP is enabled as a default setting but can be changed as follows:
Step 1.
Locate the hidden function button on the bottom side of the
extender (either on TX150 or RX150).
Step 2.
Press and keep pressed the hidden function button by a thin tool
(e.g. paper clip) for at least 10 seconds (pressing the button for a
shorter period changes the USB mode instead). If the extenders
are in HDMI mode the ‘HDCP enable’ LED status is changed before
releasing the button.
ATTENTION!
The HDCP setting can be changed in DP mode, but in this
case the ‘HDCP enable’ LED will not show the change. The setting will be effective only after switching to
HDMI mode. In DP mode HDCP is always enabled.
INFO:
The HDCP setting is available in both extenders.
