Thanks for purchasing our product.
Please be sure to read this instruction manual
carefully before using our product.

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.

4) Control command format
If user want to write his own control software, below are data format and baud rate setting.
Com port setting:
Baud Rate: 9600 bps
Data bits: 8 bits
Parity: None
Stop bits: 1 bit
Flow control: None
The command format as follow:
Cir + ‘_’ + code + ‘ ’↙
“Cir” is the key word, ‘_’ is Space, “Code” is the Control code, and ‘↙’ is carriage return. For
example:
“Cir 39↙” (hex: 63 69 72 20 33 39 0D 0A), when the mx0808 received this command, it will
change the Outport4 status to the next input port. ( “c”-0x63,”I”-0x69,”r”-0x72,”
“-0x20,”3”-0x33,”9”-0x39, ‘↙’-0x0d0a)
5) Control code (MX0808-311)

When you send a control command to the MX0808, if succeed, it will feedback current output
port status to show which input port is selected. The return status format is as follows:
For example, if you send “cir 44↙” to MX0808,if succeeds, it will feedback “s55”, meaning
OutPut5 selects InPut5.

6) Read Status Command
The command length is 4 bytes.
bc + ‘_’ + ‘ ’↙
“bc” is the key word, ‘_’ is Space, ‘ ’ is carriage return.↙
When you send the read status command to MX0808, if succeeds, it will feedback the status of
all outputs. When you send “Bc” to MX0808, if succeed, it will feedback the current status of
MX0808.
For example, if you send "bc ↙"to MX0808,if succeeds, it will feedback
"s11\r\n" ,"s22\r\n" ,"s33\r\n" ,"s44\r\n" ,"s55\r\n" ,"s66\r\n" ,"s77\r\n" ,"s88\r\n" .it means that
the output 1 select the input 1, the output 2 selects the input 2, output 3 selects the input3,
output 4 selects the input 4, output 5 selects input 5, the output 6 selects the input 6, the output
7 selects the input 7, the output 8 selects the input 8.
7) Web password reset
The command length is 4 bytes.
rpw+ ‘↙’
“rpw” is the key word , ‘↙’ is carriage return.
When you send the Web password reset command to MX0808, if succeed, it will feedback "rpw",
and the web password will be set as "0000000000".
4. LAN Control.
Note: Use the direct UTP cable to connect with PC, or use cross cable to connect to the Ethernet
switcher
A.When NETCTL run on PC at the first time, it will create a file ‘NETCTL.TXT’. This file is
for device information’s backup. These information include MAC address of MX0808, IP
address, device name etc.
Double click NETCTL.exe to run NETCTL. It will search the device. If the device is a new one,
NETCTL will list it‘s IP address. If IP address appears, please click the button .
NETCTL will change the IP address to device name.

If you want to change the device name. Right-click the device name. A pull down menu will be
displayed. Click the item ‘Rename’ to rename it’s name.
B. Double click the device name, or click right button and click the ‘open’. A web browser
will be shown. The default password is "0000000000", input the password and login. The
device controller page will be displayed.

The right area is for device controlling. Click these buttons to control the device. It is the same as
using the remote controller. The left area shows which input ports are being chosen by the output
ports.
C. When ‘Assign IP’ is displayed, it means that the device has not been assigned IP
automatically. Double click this item. Or click right button and click ‘Assign IP’ on
the pull down menu. You can assign the IP address in the Assign IP dialog.
Click OK after assign the new IP and to return to the previous dialog. Click
and . The device can be displayed correctly.
ATTENTION：here assign IP is different from SetIP in COMCTL. SetIP in COMCTL is save the IP
address in flash, when the mx0808 power on, it will read the IP from flash and set it as static IP.
Assign IP function used when automatically obtain IP address failed. This assigned IP address
is not save in flash.

5. IR call back from remote locations to control the HDMI
Matrix MX0808-311. You can use the MX0808-311’s remote
through the IR RX of the UTP receiver to change the input
channel for the UTP out of the MX0808-311, just changing this
UTP output.
This function can be set on or off: press the output1 button and the output8 button at the same
time for about 3 seconds. The LEDs will display ‘IR ON’ or ‘IR OFF’. Push the ‘ENTER’ button or
wait for 3 seconds. MX0808-311 goes into normal working condition.
6. Instruction of TX IR.
The sequence of "TX IR1,TX IR2,TX IR3,TX IR4,TX IR5,TX IR6,TX IR7,TX IR8" one-to-one
correspond with "HDMI INPUT1,HDMI INPUT2,HDMI INPUT3,HDMI INPUT4, HDMI
INPUT5,HDMI INPUT6,HDMI INPUT7,HDMI INPUT8". When an output chooses certain input,
the call-back IR signal of RJ45 on this output port will choose the corresponding "TX IR" port to
send the signal out.
For example, OUTPUT1 chooses INPUT3, then the call-back IR signal of RJ45 on OUTPUT1 will
choose "TX IR3" to send the signal out.
