Transfer the signal on [Y] card from the input channel [x1] to the output channels [x2],

[x3] and [x4].

Notice 1 :
[Y] is the floating number, ranging from 0~9. It indentifies the ID of each card.
If [Y]=1, it means you are controlling the first slot.
If [Y]=3, it means you are controlling the third slot.
If [Y]=0, it means you are controlling all the slot at the same time.
If you forget to enter “&[Y]+”, the MTX will default it as “0”.

Notice 2 :

1. MXDV4 (DVI 4X4) card does not support the “video mute” function.

2. MXUS8 (USB 8X8) doesn’t support crosspoint switching. It supports one-to-one switching
only. For example, we have signal from input 1 to output 2 now, if we switch to output 4 then
output 2 will be cut off automatically.

Detail Examples:

1、 Transfer signal on [Y] card from one input channel to all output channels:

&[Y] + [x]All.

Example: To transfer signal on the second card from the input channel No.3 to all output channels.

9. Troubleshooting & Maintenance

1) When the output image in the destination device connected to the MTX Matrix 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, it may be the unmatched RGBHV connector
order between the input and output end.

3) When the remote controller doesn’t works:
A. Maybe the battery is run out of, please change a new one.
B. Maybe the controller is broken, please ask the dealer to fix it.

4) When user can not control the MTX Matrix 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 , the beeper beeps but without any output image：
A. 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.

B. 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.
C. Please make sure the destination device is exactly on the controlled output channel
D. If it is still the same after the above checking, it may be something wrong in the switcher.

Please send it to the dealer for fixing.

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

7) If the static becomes stronger when connecting the BNC connectors, it may be due to the incorrect
earthing of the power supply, Please earth it again correctly, and otherwise it would bring damage
to the switcher or shorten its natural life.

8) If the Matrix can not be controlled by the keys on the front panel, RS232 port or remote controller,
the host may has already been broken. Please send it to the dealer for fixing.
