1. Introduction
1.1 About DVI Matrix Switcher System
CSW-DVI440A Matrix switcher is a high-performance digital signal switcher that can be used for
cross switching of multi computer and audio signal. Independent DVI component and I/O
terminals make each component signal transmit and switch separately; this design can reduce
attenuation of signal transmission to minimum and output the image and audio signal in
high-fidelity quality.
CSW-DVI440A swit cher mostly apply in broa dcasting TV engineering, multi-media meeting roo m,
big screen display engineering, television education, command control center or other fields. A/V
timing or separating switching function. With RS232 interface, it can be worked with PC, remote
control system and any other far -end control system devices.

6. Operation of the EDID management
CSW-DVI440A matrix switcher is built in the EDID manage ment database. The E DID management can
be automatically shake ha nd, or manual exchanged, and fa ct or y restore.
6.1 EDID autom a t ically shake hand
The CSW-DVI440A matrix switcher is built in the EDID data, which can communicate with the
displayers and video source automatically. When the displayers or video sources are connected to the
CSW-DVI440A matrix switcher, they will share the EDID/DDC information with the matrix switcher.
The communication solut ion is like this:
The CSW-DVI440A EDID database includes most popular displaying data, but not all the displaying
data because of the capability and firmware limitation. So, we can manually refresh the EDID data to
update the EDID data base.
6.2 EDID management of CSW-DVI440A
The RS232 commands for EDID management of CSW-DVI440A include: ”EDIDMon.” & ”EDIDMoff.”
(Please notice the text-t r ansf orm, and the dot in behind.)
These two commands only accept by CSW-DVI440A, in the other CSW-DVI440A matrix models they
are unavailable.
6.2.1 Erase and Refresh the EDID data
When the “EDIDMOn.” is sent, CSW-DVI440A will auto copy t he mix EDID data of all outputs. It means
the CSW-DVI440A will erase the old EDID data, and copy the EDID data w hich all out put disp lays have.
6.2.2 EDID restore to fact ory default
When we send the “EDIDMoff.” to the CSW-DVI440A matrix switcher, it will recover the factory default
EDID data.

6.2.3 RS232 feedback:
When the “EDIDMOn.” or “EDIDMoff.” is correctly sent, all the connected displayers will be blank for
2~3 seconds and recover again. And, CSW-DVI440A will send out a RS232 feedback command
“EDIDMOn.” or “EDIDMoff.”.
7. Operation of the Control Panel
7.1 Front Panel Descripti on

Oper ation: Press buttons in this order: “ 3” in INP UT area, “1” in OUTPUT area.
7.2 Command Format of the Switching Operation
With the front control panel, the switcher could be control directly and rapidly by pressing the buttons
under below format.
“Menu” +“Input Channel” +“Output Channel 1”
“Menu”: “AV”, “Audio”, “Video”
“Input Channel”: Fill with t he number of input channel to be controlled
“Output Channel”: Fill with t he number of output channels to be cont r olled

8. Usage of the Remote Controller
With the infrared remote controller, the matrix switcher could be control remotely. Because the function
buttons on the remote controller are the same with the ones on the front control panel, the remote
controller shares the same control operation and command format with the control panel.

11. Troubleshooting & Maintenance
1) When the output image in t he dest ination device connected to the DVI Matrix (CSW-DVI440A) 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 DVI cables haven’t been
connected as DVI criterion
3) When the remote controll er 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 t o fix it.
4) When user can not control the DVI Matrix (CSW-DVI440A) 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) If there is not “beep” sound when switching the I/O signal, please make sure the beeper is
switched-on. If so, the beeper inside the matrix may be broken. Please send it to the dealer for
fixing.
6) When switching , the beeper beeps but without any output i mag e：
A. Check with oscilloscope or multi meter if there is any signal at the input en d. If there is no si gn al
input, it may be the input connection cord broken or the connect or s 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 out put connection cord broken or the connectors loosen.
C. Please make sure the destination device is exactly on the controlled outpu t 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.
7) If the output image is interfered, please make sure the sy st em is earthed well.
8) If the static becomes stronger when connecting the DVI 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 nat ur al life.
9) If the Matrix cannot 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.
