INITIAL SETUP

• 

Connect a single CAT5e/6/7 cable between the Receiver and Transmitter using the HDBaseT ports.

• 

Connect HDMI cable between the Transmitter’s HDMI Input and source device (e.g. blu-ray player).

• 

Connect HDMI cable between the Receiver’s HDMI Output and the display device (e.g. TV).

• 

Connect IR cabling and emitter for control of the video source.

• 

Connect IR cabling and emitter for control of the display.

• 

Connect RS-232 cables. NOTE: Connect before applying power to the extender set or damage to the 

device may result.

• 

Connect Ethernet cables to Ethernet network and remote devices.

• 

Connect audio cables to TV and audio system.

• 

Connect power supply to the VXT-UTx Transmitter.

• 

Check the LEDs on the HDBaseT ports to ensure correct installation and connection: 

- The Yellow LED will illuminate when connected to a video link 

- The Green LED will illuminate when the device is connected to the power supply

• 

Check the IR activity on the IR Indicator LEDs (A):  

- The Receiver’s LED will flash Green when IR signals are being received 

- The Transmitter’s LED will flash Red when IR signals are being sent

INFRARED CONTROL

The VXT-URx and VXT-UTx provide bi-directional infrared transmission for control of the video source and 

display. The infrared commands received by at an RX input will be delivered over the HDBaseT cable to 

the TX output of the other device, where an emitter can be connected and installed on the device being 

controlled. 

Video Source IR Control

An RTI control system may be used for control of the video source directly. Alternatively, IR control of the 

video source may be sent to an infrared receiver and passed through the VXT-URx to the VXT-UTx. Plug 

the IR emitter to the TX Out and install the emitter over the source’s IR sensor.

NOTE: The IR receiver should be mounted underneath the display (TV) with the smallest end forward and 

the sticky pad affixed upwards. (NOTE: IR Receiver is square with a shiny surface). 

Display IR Control

An RTI control system may be used for control of the display directly. Alternatively, IR control of the 

video source may be passed through the VXT-UTx to the VXT-URx. For IR control of remote devices 

(e.g. Display) from a control system, connect to IR output of control processor. NOTE: Requires Mono to 

Stereo cable, with stereo end plugged into VXT-UTx. Plug the IR emitter into the VXT-URx TX Out and 

install the emitter over the display’s IR sensor.
