The GCS712U MiniView Micro USB Audio KVM switch is a control unit that allows access to two
computer systems from a single console (keyboard, monitor, and mouse).
The GCS712U improve on previous models with a 50% smaller desktop footprint plus built-in custom
KVM cables for trouble-free installation and a neat and tidy workspace. For increased efficiency and
cable compactness, each of the GCS712U’s cables use a USB connector (rather than two PS/2
connectors) to transfer keyboard and mouse input to the computer.
Recognizing the increased importance of sound, the GCS712U is speaker enabled. You can listen to the
audio output of both computers (one at a time) on a single set of speakers attached to the Switch.
Setup is fast and easy; plugging cables into their appropriate ports is all that is entailed. There is no
software to configure, no installation routines, and no incompatibility problems. Since the GCS712U
intercepts keyboard input directly, it works on any hardware platform and with all operating systems. It’s
compatible with Windows and Mac computers as well as Sun Solaris workstations.
There is no better way to save time and money than with a GCS712U installation. By allowing a single
console to manage both computers, the GCS712U eliminates the expense of purchasing a separate
keyboard, monitor, and mouse for each computer. Additionally, it saves the extra space they would take
up, and eliminates the inconvenience and wasted effort involved in constantly having to move from one
computer to the other.
