Use the ServSwitch™ Micro to access two
computers from a single shared monitor,
keyboard, and mouse. Two high-quality,

the connections to the two computers.
Three models are available. They vary only
in the number and type of connectors. All
three models have audio connectors. See
the Connectors specification in Chapter 1.
All models are plug and play and can be
computer selected for easy setup and
installation. They also have two status LEDs
and advanced video enhancement
technology for crisp, clear VGA quality up
to 1920 x 1440. Computer switching is
flawless, and PC startup is trouble-free.
