Introduction
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. The console connection
uses a set of USB mouse, keyboard, monitor with 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
compatibility to save space and cost.
