Introduction
MX0808-311 is an 8-by-8 DVI/HDMI true matrix. It allows any of the eight
source (Blue-Ray player, HD DVD player, satellite receiver, game system, etc.)
to be routed to any of the eight displays simultaneously, no matter the source is
HDCP or not. Users can choose several different ways to control the matrix: by
using infrared extension receiver, RS232, RS485, and LAN and supplied
remote control. IR emitters in the matrix are for controlling the sources; the IR
control signal could be from remote locations via STP/UTP type HDMI
connection on the rear panel.
MX0808-311 has the ability of equalization and amplification to ensure HDMI
signal's transmission through long cable without quality loss. The transmission
distance of STP/UTP outputs reaches up to 50 meters under the vedio format
of 1080P, together with infrared control signal.
MX0808-311 offers solutions for digital entertainment center, HDTV retail and
show site, HDTV, STB, DVD and projector factory, noise, space and security
concerns, data center control, information distribution, conference room
presentation, school and corporate training environments.

■Connections and Operations
1) Connect the HDMI input source ( such as HD-DVD/ PS3 /STB etc.)Into MX0808-311.
2) Connect the standard HDMI outputs ( such as HD-LCD, HD-DLP) into MX0808-311.
3) Connect two CAT-5E cables to both the STP/UTP outputs of MX0808 - 311 and inputs of
STP/UTP receiver ( such as EX0101-U31/33/51/53 etc). Please pay attention to the
sequence of the two cables, CAT5e-1-> CAT5e1, CAT5e-2- > CAT5e2. ( The cable
termination must follow the standard of EIA/TIA 568B, if Single UTP mode, just connect
CAT5E -2).
4) Connect the HDMI output ( such as : HD-LCD、HD-DLP ) into the STP /UTP receiver.
5) Connect the IR RX receiving cable into STP/UTP receiver IR RX and connect the IR TX
cable into MX0808-311 IR emitter.
6) Power on the input source you want to show. ( Keep the unused input power off,
otherwise it may interfere the normal display).
7) Connect the power supply into MX0808-311.
8) Turn on the power, when the LED panel stops flashing circularly, the initialization of the
matrix are ready.
9) Turn on the displays you want to watch.
10) Use the remote supplied or pushes the button on the front panel to choose input source, or
using infrared extension receiver, RS232, RS485 or LAN port to do the control.
