Overview
KVM switches can save money and human cost in multiple computer systems.
Users need not to purchase a separate keyboard, monitor and mouse for each
computer. They allow users to access and control up to 2 (AS-21DA) or 4
(AS-41DA) computers from a single USB keyboard, USB mouse, and DVI
monitor console. The setup is easy and there is not software to configure, this
lowers the difficulty of usage.
KVM AS-21DA/ AS-41DA with audio supports control of 2 (AS-21DA) / 4
(AS-41DA) computers using a set of keyboard, mouse, monitor and speaker.

general DVI interface and a stereo speaker or earphone. It transfers keyboard
and mouse data between KVM and host with USB interface. It helps users to
setup multiple computer system with lowest cost and highest compatibilityto
