HP LD4730 47-inch Micro-Bezel Video Wall Display - Manual (Page 40)

Controlling displays with IR Daisy Chain
The LD4730/LD4730G provides the capability of using IR Daisy Chain to enable selectable control of
the displays locally, using the IR Remote Control when the displays are mounted in a video wall. You
may control one display at a time by selecting the ID of the display, or you may control all the displays
simultaneously by selecting an ID of “00”.
Setting up IR Daisy Chain
The following describes how to set up the displays for IR Daisy Chain
1. Insert the External IR Sensor into the IR IN (blue) jack at the back of the display
2. Using the included IR Daisy Chain Cable, connect all the displays in the video wall. See
Connecting cables on page 15 for details.
3. Using the IR Remote Control or the display control buttons, go to MENU → OPTION 2 → SET
MONITOR ID and set the unique ID number (number between 1 and 25) for each display in the
video wall
4. Using the IR Remote Control or the display control buttons, go to MENU → OPTION 2 → IR
OUT and chose ENABLE for each of the displays in the video wall
5. Using the double sided tape, locate the External IR Sensor away in a spot where it will be easy
to point the IR Remote Control. It is recommended that the sensor be located at the top left or
right of the video wall.
NOTE: Care should be taken to avoid locating the sensor next to the bottom of any of the displays
where the IR sensor of the display could sense the IR Remote Control or where the sensor might
block the viewing area of any display.
Controlling displays with the IR remote control
Point the IR remote control at the External IR Sensor and press the MENU button. The IR Daisy
Chain home menu will appear on each display, with the Monitor ID displayed so you can easily
identify the display you want to issue the command to (
