In modern banking, telecommunications, shopping malls and other customer self-service management, security monitoring, remote teaching system, needs to apply the host VGA video, audio, mouse, keyboard, and so the peripheral devices signal is divided into two groups . One group on the host where the signal is locally available to the host system for managers use; the other group needs to be extended to 50-300 m via the DYE402A remote provided to the customer .

The DYLINK DYE402A is divided into transmitter and receiver two devices, Transmitters placed on the host side, in the acceptance of the VGA, audio and data signals came from the host ,which were divided into two different signals, a group of local suppliers of VGA, audio, mouse, keyboard signals to the local maintenance personnel use; another group to extend the signal, high-definition VGA signals, mouse, keyboard, audio, RS232 signal through the two RJ45 interface output, After  receiver receives the RJ45 interface coming the signal, re-converted into VGA video, mouse, keyboard, audio, RS232 signal available to remote personnel.

You can now use DYE402A host centrally located in a secure, independent and closed space, the computer video, audio, mouse, keyboard, RS232, etc. are all extended to 50-300 m outside the hall, As well DYE402A receiving equipment is smaller than the computer box . Computer cooling, security, and so on advantages are very clear.
