CHAPTER 5: HARDWARE OPERATION
5.1 EDID UPDATE BY BUTTONS
The MediaCento IPX 4K features EDID Management. In each video link of a transmitter unit (TX) and a receiver unit (RX), before
outputting the video (and/or audio) data, the source device connecting to the TX reads the EDID first to define the specification of
the video data it should support to output. The EDID can be the factory default, the display connecting to the TX or the sink device
(e.g. display, amplifier,….etc) connecting to RX, and be set up to one of these three types by pressing the “EDID Update” button
based on the application.
By default, the internal HDMI EDID (stored in the transmitter unit) is used. However, the EDID of the receiver’s HDMI output
connected device such as the display, amplifier,…etc, can be obtained and stored in the transmitter. It can support multi-channel
audio and 3D function from the device connecting to the receiver.
5.1.1 “EDID UPDATE” FOR HDMI SINK DEVICE ON TX OR RX SIDE
1. Press the “Select” button to make “EDID” LED blink in order to select the EDID Update function.
2. Press the “SET/RESET” button to set up the EDID Update function.
3. The “EDID” LED lights steady on when the EDID Update is completed.
4. In Extender device mode for TX/RX link, EDID Update will automatically perform when the video connection is established every
time or when the display connecting to Receiver unit is changed.
5.1.2 “EDID UPDATE” TO BE FACTORY DEFAULT
1. Make sure there is no function setting for “EDID”, “USB”, “V. profile” or “Video Channel” to be selected.
2. Press the button for 6 seconds to Reset to Default.
3. Do the above two steps for the transmitter and receiver of the same link.
5.2 AUDIO OVER IP EXTENSION
1. A computer has a Mic-In jack, as part of the sound card. To access this jack from the Receiver/RX unit, connect the microphone
to the Mic-in jack on the Receiver/RX unit.
2. To get the audio from the microphone into the computer, connect a 3.5-mm-to-3.5-mm stereo cable from the Line out jack on the
Transmitter unit to the Line in jack on the computer.
WARNING: DO NOT connect the cable from the Line out jack on the TX unit to the Mic In jack on the computer. Doing it will result in
audio “clipping” and may cause damage to the sound card.
NOTE: HDMI audio will always be passed through to the HDMI out connector on the Receiver unit. However, if a 3.5mm stereo cable
is connected to the Line in jack on the TX unit, the embedded HDMI audio is switched off. This allows the audio signal from Line in
jack (TX unit) to be received on the Line out jack (Receiver/RX unit).
