1. Introduction

1.1. About MMX88A

MMX88A is a high performance video and audio modular matrix switcher. Various
changeable cards make MMX88A flexible and all-in-one solution for different projects.
It can support different video signals with cross switching. Every video or audio signal
is transmitted and switched independently, this will cause the least signal attenuation,
so that make the output signal keep at high fidelity.

There are two series of changeable cards work with MMX88A, input card MMX-4I
series and output card MMX-4O series, all the cards support hot plug & play. Users
can choose the right card for different application. There are different signal card is
used for processing different video signal, including: HMDI, DVI, VGA, SDI and HDMI
TP etc.

MMX88A have power fail memory function and audio can break away from or follow
the video to switch. It has RS232 port for serial control and optional IP port for TCP/IP
control, easily to be controlled by third-part devices.

MMX88A can be used for different project, because of its changeable card design. It is
the combo solution for multimedia conference rooms, control rooms, broadcasting
rooms, shopping center etc. It will handle all the audiovisual management, including
the switching, driving, scaling etc.

1.2. Features

 Modular chassis with configurable I/O slots, ranging from 4x4 to 8x8.
 Various I/O cards, includes HDMI, HDBaseT, SD/HD/3G-SDI, DVI and VGA cards

(Compatible with YUV, YC & CVBC.) to configure any matrix.

 Truly cross-point switching, any input to any output, regardless signal format.
 Support HDMI1.4a, support 3D.
 Integrated HDBaseT technology.
 Controllable via button, RS232 & optional TCP/IP, also compatible with 3rd parties

control.

 HDCP compliant.
 LCD display.

4.5. Connection with Computer

When the MMX matrix connects to the RS232 port of a computer with control software,
users can control it by that computer. To control the switcher, users need to use RS232
control software.

4.6. Connection of TCP/IP Communication Port (Optional Function)

The MMX matrix can work with the PTN model “PTNET”, to enable the TCP/IP
function.
The PTNET is a programmable RCP/IP to RS232 processor, which is built in the FTP
and fixed IP address inside and working compatible with internet.

6.1. Operations of Buttons

Switching Operation:

With the front control panel, the MMX matrix could be control directly and rapidly by
pressing the buttons under below format.

“Input Channel” + “Switch Mode” +“Output Channel”

1) “Switch Mode”: Audio & Video synchronal or break away switching mode, which

includes buttons “AV”, “Audio”, “Video”.

2) “Input Channel”: Fill with the number of input channel to be controlled,

3) “Output Channel”: Fill with the number of output channels to be controlled.

Examples:

1) AV button: To transfer both video and audio signals from input channel No.3 to

output channel No.8.
Operation: Press buttons in this order “3”, “AV”, “8”.

2) VIDEO button: To transfer video signal from input channel No.3 to output channel
No.4.

Operation: Press buttons in this order “3”, “VIDEO”, “4”.

3) AUDIO button: To transfer audio signal from input channel No.2 to output channel
No.3.

Operation: Press buttons in this order “2”, “AUDIO”, “3”.

4) ALL button: To transfer video and audio signals from input channel No.1 to all
output channels.

Operation: Press buttons in this order “1”, “ALL”

5) UNDO button: First take command “1”, “AV”, “6”, then take command “2”, “AV”, “6”,
press the UNDO button to enter into the first operation status.

5、 Switch off the detail feedback command from the COM port: /:MessageOff;

But, it will leave the “SWITCH OK” as the feedback, when you switch the matrix.

6、 Switch on the detail feedback command from the COM port: /:MessageOn;

It will show the detail switch information when it switch. Example: when switch 1->2, it
will feedback “V01 - > 002”.

7、 Transfer signals from an input channel to corresponding output channel:
[x]#.

Example: “5#.” to transfer signals from the input5 to the output5.

8、 Switch off an output channel: [x]$.

Example: “5$.” to switch off the output 5.

9、 Switch video signal: [x1]V[x2].

Example: “3V8,9,12.” to transfer video signal from input3 to output No.8,9,12.

10、 Switch audio signal: [x1]A[x2].

Example: “6A2.” to transfer audio signal from input6 to output No.2, the feedback is
A:06- >002.

11、 Switch signal: [x1]B[x2].

Example: “1B2,3,5.” to transfer signal from the input1 to the output No.2,3,5.

12、 Inquire the input channel to the output channel [x]: Status[x].

Example: “Status23.” to inquire the input channel to the output23.

13、 Inquire the input channel to the output channels one by one: Status.

Example: “Status.” to inquire the input channel to the output channels one by one.

14、 Save the present operation to the preset command [Y]: Save[Y].

Example: “HDCPON.” to turn on the HDCP output.

22、 Turn off the HDCP output: HDCPOFF.

Example: “HDCPOFF.” to turn off the HDCP output.

23、 Command for MMX-4I-VGA: PTN/I/[X]:*****%;

Example: “PTN/I/07:0623%;” to set the input 7 to support YPbPr signal, the card is
plugged in the second input slot of the matrix.

Note: If there is any empty input card or output card, and send the command “ALL#.” It
will be taken and the result is as 1->1, 2->2, 3->3…, but actually there is no
input/output signal at this card.

8. Troubleshooting & Maintenance

1) When the output image in the destination device connected to MMX88A has

ghost, such as the projector output with ghost, please check the projector’s

setting or try another high quality connection cord.

2) When there is a color losing or no video signal output, maybe the connectors

between the input and output end do not connect tightly.

3) When the IR remote does not work:

 Maybe the cell battery has no power, please change for another battery.
 Probably the IR remote is broken, please send it for repairing.

4) When user cannot control the matrix switcher by computer through its COM port,

please check the COM port number in the software and make sure the COM port
is in good condition.

5) When switching , there is no output image:
 Check with oscilloscope or multimeter if there is any signal at the input end. If

there is no signal input, it may be the input connection cord broken or the
connectors loosen.

 Check with oscilloscope or multimeter if there is any signal at the output end.

If there is no signal output, it may be the output connection cord broken or the
connectors loosen.

 Please make sure the destination device is exactly on the controlled output

channel.

 If it is still the same after the above checking, maybe there is something

wrong in the switcher. Please send it to the dealer for repairing.

6) If the POWER indicator does not work and responses with no result when

operate, please check if the power cord is well connected.

7) If the output image is interfered, please make sure the system is earthed well.

8) If the static becomes stronger when connecting the video/audio connectors, it

may be due to the incorrect earthling of the power supply, Please earth it again
correctly, and otherwise it would bring damage to the switcher or shorten its
natural life.

9) If the matrix switcher cannot be controlled by the keys on the front panel, RS232

port or IR remote, the unit may have already been broken. Please send it to the
dealer for repairing.

9. Safety Operation Guide

In order to guarantee the reliable operation of the equipments and safety of the staff,
please abide by the following proceeding in installation, using and maintenance:

1) Unit must be earthed properly. Please do not use two blades plugs and ensure the
alternating power supply ranged from 100v to 240v and from 50Hz to 60Hz.

2) Do not put the switcher in a place of too hot or too cold.

3) As the power generating heat when running, the working environment should be
maintained fine ventilation, in case of damage caused by overheat.

4) Cut off the general power switch in humid weather or left unused for long time.

5) Before following operation, ensure that the alternating current wire is pull out of the
power supply：

 Take off or reship any components of the equipment.
 Take off or rejoin any pin or other link of the equipment.

6) As to non-professional or without permission, please DO NOT try to open the
casing of the equipment, DO NOT repair it on your own, in case of accident or
increasing the damage of the equipment.

7) DO NOT splash any chemistry substance or liquid in the equipment or around.
