INTRODUCTION

The AT-HD44M-SR 4x4 HDMI over CAT5 Matrix with IR Control Path provides the most exible and cost effective solution in the market to route high denition video sources plus multi-channel (up to 7.1-channel) digital audio from any of the four HDMI sources to the remote displays

at the same time. Through low cost CAT5/5e LAN cables, not only high quality video and audio can be transmitted to the display sites, but also users can switch among 4 HDMI sources using the push button or remote control. With single power design at the source site, each remote

module is easily installed without power supply. Furthermore, the built-in IR extension function

makes users at display site access the DVD player, PS3 or any HDMI equipped devices directly!

FEATURES:

• State-of-the-art Silicon Image (founder of HDMI) chipset embedded for upmost compatibility

and reliability

• HDMI 1.2a compliant

• HDCP compliant

• Allows any source to be displayed on multiple displays at the same time

• Allows any HDMI display to view any HDMI source at any time

• Supports 7.1 channel digital audio

• Supports default HDMI EDID and learns the EDID of displays

• The matrix master can switch every output channels to any HDMI inputs by push button, IR

remote control, or RS-232 control

• Allows controlling local HDMI sources such as DVD and TiVo by IR extender through control

path at remote receiver

• Allows to control main matrix center through control line at remote receiver

• Extends video signal up to 35m (115 feet) over CAT5e at 1080p

• Easy installation with rack-mounting and wall-mounting designs for master and receiver re-

spectively

Note:

If the HDTV shows video but without audio, please try to set audio mode to stereo.

Factory default of SW1-SW4: Pin#1-OFF & Pin#2- OFF for 1080p with stereo.

If you encounter any unsolved audio/video output problem during system installation, please turn any SW1-SW4

to Pin#1-OFF & Pin#1-ON , for safe mode to enforce the most compatible 720p stereo output for system check.

Bypass means the matrix will maintain playing the original format of HDMI signals in video and audio. By

setting at this mode, the users may encounter compatibility issue among different kinds of HDMI sources and displays. If you cannot get the audio and/or video output normally at the system installation, please change the DIP switch setting to default mode or even safe mode to verify the functionality of the device.

Set Pin#1 at ON ﬁrst then connect the HDMI Input to HDTV through a HDMI cable. Wait for 20 seconds. The

EDID learning procedure will be ﬁnished. If you want to learn the EDID from another HDTV, you must set Pin#1 at OFF ﬁrst and repeat this procedure.

FIRMWARE UPDATE

Warning!

There could be unexpected consequences resulted from inappropriate ﬁrmware update operation. Please do it with caution.

1. Please unzip the Matrix_Firmware_Update.zip into your designated folder.

2. Please turn off the power of the MATRIX and set DIP location of [SW Main] at Pin#1-ON , Pin#2-ON , Pin#3-OFF , & Pin#4-OFF .

3. Please execute the ﬁle Matrix_Firmware_Update.exe

4. In the pop-up window, at [Select Chip], please select W78E365.

5. In the pop-up window, at [Select File], please choose the BIN ﬁle in the designated

folder, as shown in the picture.

6.In the pop-up window, please select the [File Format] to Binary.

7. Please make sure your PC has direct connection to the RS-232 port of the MATRIX, as

shown in the picture (left), that in [Communication Setting] the onlne status should be “Wait to

connect”. If the RS-232 connection is not ﬁrmly established, you will see the online status is

“Disconnect.” If so, please check the RS-232 connection until the online status becomes “Wait to Connect.”

8. Please turn on the MATRIX. The ﬁrmware update process will automatically initiate.

9. The ﬁrmware update process is successful if you see the [Information] window pops up to

inform you that the process is complete. If you see the [Error] window pops up, please turn off the MATRIX and turn it on again. If necessary, please redo the whole sequences 1-9.

10. The message “Program: OK!” means the ﬁrmware update process is successful. If you see

the [Error] window pops up after the message [Program: OK!], please ignore it.

11. Turn off MATRIX. Set DIP location of [SW Main] at Pin#1-OFF , Pin#2-OFF ,

Pin#3-ON , & Pin#4-OFF .

12. Turn the MATRIX back on and return to normal operation.

NOTICE

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

2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e

125MHz LAN cable and ASTRODESIGN Video Signal Generator VG-859C.

3. The transmission length is largely affected by the type of LAN cables, the type of HDMI sources, and the type of HDMI display. The testing result shows solid LAN cables (usually in bulk cable 300m/1000ft form) can transmit a lot longer signals than stranded LAN cables (usually in patch cord form). Shielded STP cables are better suit than unshielded UTP ca-

bles. A solid UTP CAT5e cable shows longer transmission length than stranded STP CAT6 cable. For long extension users, solid LAN cables are your only choice.

4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.

5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you can use shielded LAN cables to improve EMI problems, which is worsen in long transmis-

sion.

6. Because the quality of the LAN cables has the major effects in how long transmission distance will be made and how good is the received display, the actual transmission length is

subject to your LAN cables. For resolution greater than 1080i or 1280x1024, a CAT6 cable is

recommended.

7. If your HDMI display has multiple HDMI inputs, it is found that the rst HDMI input [HDMI input #1] generally can produce better transmission performance among all HDMI inputs.

8. The AT-HD44M-SR has been tested extensively and found that it doesn’t require external power supply. If in rare situation you nd it cannot work with the AT-HD44M-SR, please use any +5V power adapter to plug in the power jack and see if it can work. If not, please contact your technical support for further service.

9. Additional IR remote controls and IR emitter cables can be purchased as optional accessories to control the HDMI sources located separately.
