The EDID learning function is only necessary whenever you encounter any display on the HDMI output port that cannot play audio and video properly. Because the HDMI source devices and displays may have various level of capability in playing audio and video, the general principle is that the source device will output the lowest standards in audio format and video resolutions to be commonly acceptable among all HDMI displays. In this case, a 720p stereo HDMI signal output would be probably the safest choice. Nevertheless, the user can force the matrix to learn the EDID of the lowest capable HDMI display among others to make sure all displays are capable to play the HDMI signals normally by performing the procedures stated below.

SW1-SW8 Pin#1 and Pin#2 must be set “ON” & “OFF” for EDID Learning Mode

Method 1: Manually connect HDMI displays to HDMI input ports

1. Power up the matrix master unit. Connect the HDMI display that its EDID needs to be learned to any of the

HDMI INPU1-INPU8 port where your source device has trouble to show the picture normally.

2. To learn the display’s EDID for source device connected to respective HDMI INPU1-INPUT8 port, pull

both pins of respective DIP switch SW1-SW8 up-and-down to stay at ON[]-OFF[] and wait for about 5 seconds to complete the EDID learning process. You DON’T NEED to pull up the DIP switch again unless you want to learn another display’s EDID by pulling both DIP switch pin-1 & pin-2 of SW1-SW8 up-and-down one more time.

3. Repeat step1 & step2 if you want to learn the EDID of this HDMI display on any other HDMI input ports

that have same trouble playing the audio/video properly.

1. When adjusting the signal level on the receiver unit, please dial the rotary control switch from 7 to 0

and stop turning the rotary switch whenever the audio/video is playing normally. Inappropriate signal level setting may cause overpowering issue that would shorten the product life significantly!

2. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to retrieve and

provide DVI or HDMI display EDID information.

3. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP

cable and ASTRODESIGN Video Signal Generator VG-859C.

4. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI sources,

and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 300m [1,000ft] bulk cables) can transmit a lot longer signals than stranded UTP cables (usually in the form of fixed length patch cords). Shielded STP cables are better suited than unshielded UTP cables. A solid UTP Cat-5e cable shows longer transmission range than stranded STP Cat-6 cable. For long extension applications, solid UTP/STP cables are the only viable choice.

5. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.

6. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can

use shielded STP cables to improve EMI problems, which is worsen in long transmission.

7. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit can

achieve and how good is the received picture quality, the actual transmission range is subject to one’s

choice of Cat-5/5e/6 cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-6 cable is recommended.

8. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]

generally can produce better transmission performance among all HDMI inputs.

9. The MA-5188RX has been tested extensively and found that it doesn’t require external power supply. If

10. Additional IR remote controls and IR blaster cables can be purchased as optional accessories to

control the HDMI sources located separately.

1. The quality of output video is not good enough, how can I do?

Please adjust the 8-level equalization on the receiver units. The HDMI signal level varies from 0 (strongest) to 7 (weakest) for respective transmission length from longest possible range to short distance. It is recommended to switch from 7 to 0 to find the optimal visual experience.

2. Can I use any kind of LAN cable?

Please check the NOTICE section for more information about how to pick up a suitable cable.

3. Can every TV work with the HDMI matrix?

Basically, the answer is YES. But if your TV can not support 1080p, please refer the EDID LEARNING section to learn EDID from your TV.

4. What is EDID? Why do I need to learn EDID?

EDID contains the whole information of the display such as the resolution and audio setting which this display can support. Therefore, based on the EDID information, media player will pick up the most suitable resolution and audio setting to the display. In order to faithfully transmit the EDID information from display to the media player, learning EDID from display to this device is necessary.

5. What should I do to learn EDID for the matrix?

Due to the limitation of HDMI, the source device can only output one format of video and audio. In other

words, the source device cannot output 720p and 1080p video at the same time, or output stereo and

surround sound at the same time. Therefore, you may need to manually setup the DIP switch for each

HDMI input for desirable audio/video output format. The mechanism of EDID Learning is to pick up the

HDMI display with the lowest capability among the ones you would use for this input source. For example,

if user would like to play the Input-2 upon output-3, output-5 and output-8, and only output-5 cannot

support 1080p [support up to 720p only], please learn the EDID from the display connected to the

output-5 at the Input-2 port. Of course, if outpt-5 could get the HDMI signals from every HDMI input,

please learn EDID information from output5 to all eight HDMI inputs. For more information about EDID

Learning, please refer to EDID LEARNING section.

6. My TV can support 1080p, but why there is no audio?

The default setting of this device is 1080p & 7.1ch audio, so there would be a problem if the TV cannot support 7.1ch audio. Please change the DIP switch of the chosen input from Default Mode to Safe Mode.

FAQ

Page 26

~ 25 ~

7. When I set an audio amplifier (AV receiver) between TV and the matrix to extract 7.1ch audio, but why

there is still no audio?

Basically, the default DIP switch setting of the chosen input can support 7.1ch audio, but the problem is that the EDID of the amplifier still cannot match the default setting. Therefore, the best method is to learn EDID from the amplifier directly. Please refer to EDID LEARNING section and follow the steps to learn the EDID. When learning EDID from the amplifier, user just needs to connect the matrix and amplifier. Please don’t connect HDMI cable between amplifier and TV when the EDID learning is proceeding.

8. When I play the same content upon multi-displays, why only the TV equipped with amplifier can have

7.1ch audio, and the others don’t have 7.1ch audio even no stereo?

Due to the limitation of HDMI, the source only can choose one video and one audio format to play, which can be either 1080p and 7.1ch or 1080p and stereo audio. It means when the user sets the matrix at 1080p and 7.1ch, the source will only play the content under this format. Therefore if the TV cannot decode 7.1ch audio, there is definitely no audio.

9. Is there an easier method that can allow this matrix switcher to work properly?

Please refer to the third method of EDID learning to switch among different default EDID profiles at the remote side. Through the switching from 1st to 5th default EDID profile, stay with the one that can get the audio and video as you wish.

10. I have tried every method above, why there is still no audio anyway?

It is because the media player cannot recognize the EDID of the display. Therefore please adjust the DIP switch of this input to EDID Learning & Stereo Mode to have audio properly.
