KB01088 - How to control sources from HDBaseT output zones on a UHD-PRO3


The UHD-PRO3 matrix system is smart and is able to recognize IR commands being received from its output (via a compatible HDBaseT receiver and IR Receiver) and route those commands to the corresponding source being displayed in that output zone.  There is no special programming required to utilize this feature.

To allow for IR signal to be received at an output zone to control a source device, you will need to have a compatible IR receiver:

  • Atlona recommends using the AT-IR-CS-RX (you can also use any third party 12v IR Receiver)
  • Atlona’s IR Receivers come with three wires: The dashed wire = Signal (S), The solid striped wire = Power (P) and the plain wire is Ground ():  


To configure the connection of an IR receiver/emitter on a UHD-PRO3 HDBaseT receiver and matrix:

  • The 12v IR receiver (AT-IR-CS-RX) would need to be connected to your HDBaseT receiver (such as the AT-UHD-EX-70C or AT-UHD-EX-100CE or any other compatible RX extender) which will pick up the infra-red commands being sent.
  • Atlona IR receivers will flash red to show that an IR signal being received: (AT-IR-CS-RX flashing RED to show IR being received)
  • Please note for IR to pass you do need a solid link and power between matrix and RX extender. Check link and power LED’s to ensure they are solid. If no link is present, please try replacing CAT cables or see our guide on troubleshooting link issues.
  • At the back of the Matrix, connect your IR emitter (1 x AT-IR-CS-TX is included with AT-UHD-PRO3 compatible receivers such as the AT-UHD-EX-70C-RX and AT-UHD-EX-100CE-RX):(AT-UHD-PRO3-88M IR Out screenshot)
  • The AT-IR-CS-TX has two wires that will need to be connected to the IR Output of the Atlona matrix that corresponds with the HDMI inputs: Solid stripped wire = Signal (S), plain wire = Ground () :

  • Once connected to the back of the matrix, position the AT-IR-CS-TX on the IR Window (aka IR Eye) of your source device. If attempting to control more than one source from a single emitter output, Atlona recommends placing two emitters into one port. While this will drop the voltage on the emitters, placing them directly on the front of a source will still allow IR signal to pass.
  • The AT-IR-CS-TX will flash a red LED to show an IR signal is being emitted:

  • Some emitters do not flash and since the human eye cannot see IR, Atlona recommends testing IR from an emitter with a digital camera (if using a cellphone, use the front camera as this does not have an IR filter as the main camera typically does)
  • With your IR Receiver and IR Emitters are properly connected, you should have the ability to control your sources that are routed to a specific output(s) zone in which you are sending the sources IR commands for that specific device. For example, viewing Input 1 on HDBaseT Output 3 means that sending an IR command to the IR Receiver at the TV in output zone 3 (HDBaseT 3) will automatically output IR from the IR OUT #1 port (which corresponds to HDMI input 1).
