Introduction
Overview
The GCL1908 / GCL1916 LCD KVM Switch features an integrated 19" LCD
panel allowing access and control with up to 8 or 16 computers from a single
console (keyboard, mouse, and monitor). As many as 8 (GCL1908) or 16
(GCL1916) additional switches can be cascaded bringing the total number of
connectedcomputers to 128 (GCL1908) or 256 (GCL1916) computers that
can be controlled from a single keyboard-monitor-mouse console.
Additionally, the GCL1908 / GCL1916 features a compact design that allows
installation in a 1U system rack.
Setup is fast and easy; plugging cables into their appropriate ports is all that is
needed. The switch supports both USB and PS/2 connections for the console
and computers. The GCL1908 / GCL1916 intercepts keyboard input directly,
thus eliminating the need for any software configuration. Switching between
computers can be easily accomplished either by manually pressing the front
panel push button port LEDs, entering hotkey combinations from the
keyboard, or via a menu driven multilingual on-screen display (OSD) system.
A convenient auto-scan feature permits automatic scanning and monitoring of
activities on all connected computers. Lastly, the GCL1908 / GCL1916 offers
the following additional benefits: a) integrated 19” LCD, keyboard and
mouse console, b) managing 8/16 computers from a single console, c)
eliminating the expense of having to purchase a separate keyboard, monitor,
and mouse for each computer, d) space and energy costs savings, and d)
creates a greener environment by reducing energy waste.
