includes button “AV”.

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.

4) MMX1616 needs to use “,” button to separate multiple outputs, and “ENTER” button

to confirm the operation.

5) The input/output channels on the rear panel are counting from left to right,

top to bottom. And if the input/output channel is two digits number, the input
delay time between two numbers must less than 5 seconds; otherwise the
operation will be cancelled.

Except the front control panel, the MMX matrix can be controlled by far-end control
system or through the Ethernet control via the RS-232 communication port.
This RS-232 communication port is a female 9-pin D connector. The definition of its pins
is as the table below.

PTN Electronics Limited 11 www.PTN-electronics.com

Notice: Cable connectors MUST be metal one, and the shielded layer of cable MUST

be connected to the connector’s metal shell, to well share the grounding.

5.4. 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.

5.5. 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.
For more details, please check the user manual of PTNET.

to the model of the matrix switcher. If the symbols exceed the effective range, it would
be taken as a wrong command.

3. In above commands, “[”and “]” are symbols for easy reading and do not need to be
typed in actual operation.

4. Please remember to end the commands with the ending symbols “.” and “;”.

4->4……16->16.

3、 Switch off all the output channels: All$.

Example: After running this command, there will be no signals on all the outputs.

4、 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.

5、 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 “AV01 to 02”.

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

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

7、Switch off an output channel: [x]$.

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

8、Switch signal: [x1] B[x2].

Example: “12B12,13,15.” to transfer signal from the input12 to the output No.12,13,15.

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

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

10、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.

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

Example: “Save7.” to save the present operation to the preset command No.7.

12、Recall the preset command [Y]: Recall[Y].

Example: “Recall5.” to recall the preset command No.5.

13、Clear the preset command [Y]: Clear[Y].
Example: “Clear5.” to clear the preset command No.5.
14、EDID management command:. EDIDM[X]B[Y].

Example: “EDIDM5B3.” to copy the EDID data of the display on output5 to input3.

15、Command for MMX-4I-VGA: PTNI[X]*****.

Example: “PTNI070623%.” to set the input 7 to support YPbPr signal, the card is
plugged in the second input slot of the matrix.

8. 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.

9. Troubleshooting & Maintenance

1) When the output image in the destination device connected to MMX1616 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 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.

4) 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 fixing.

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

6) If the static becomes stronger when connecting the video 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.

7) If the matrix switcher cannot be controlled by the keys on the front panel, RS232
port or IR remote, the unit may has already been broken. Please send it to the
dealer for repairing.
