DVI Matrix Switcher 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.

DVI Matrix Switcher 6. Operation of the EDID management CSW-DVI440A matrix switcher is built in the EDID management database. The EDID management can be automatically shake hand, or manual exchanged, and factory restore. 6.1 EDID automatically shake hand The CSW-DVI440A matrix switcher is built in the EDID data, which can communicate with the displayers and video source automatically.
DVI Matrix Switcher 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 Description “AV” AV synchronal button: To transfer video and audio signal synchronously by the switcher Example: To transfer both the video and the audio signals from input channel No.
DVI Matrix Switcher 2, Press the button for input channel number“1” 2 2 3 3 4 4 3, Press the button for the first output channel number “3” ” 4, Press the button for the second output channel number “4” Then, switching OK! audio/video switching from “1” to “3” and “4” 8. Usage of the Remote Controller With the infrared remote controller, the matrix switcher could be control remotely.

DVI Matrix Switcher 11. Troubleshooting & Maintenance 1) When the output image in the destination 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 controller doesn’t works: A. Maybe the battery is run out of, please change a new one.
