Set Up a Live Capture - Decimator MD-HX (HDMI to HDMI)

For infor­ma­tion on the Decimator MD-HX, check out the Capture Hardware Recommendations page.

This con­nec­tion guide for using the Decimator means that the fol­low­ing fac­tors are true:

  • The video source is con­nect­ed to the Decimator using an HDMI connection
  • The Decimator is con­nect­ed to the AJA U-TAP using an HDMI connection

  2. Plug your HDMI video source into the HDMI Input.

  3. Plug an HDMI cord into the HDMI Output.

  4. Press the Enter but­ton to wake the device if the front LCD screen is not already on.

    If you have a video feed com­ing in through the HDMI cable, you should see a sig­nal appear­ing in the H row.
