------------------- Introduction
Overview
The CL-KVM-DAAG-112 and CL-KVM-DAAG-114, fully
compatible with USB specification, are the combination of USB
KVM (keyboard/Video/mouse) switch and USB peripherals
sharing device. With the 2/4-Port USB KVM switch, you can
easily operate up to 4 PCs, G3/G4 Macs, or iMacs respectively
from 1 USB keyboard, 1 USB mouse, and 1 DVI monitor saving
you space, time, equipment and money. The peripheral sharing
function enables you to share more USB peripherals among all
computers. The “FUNC” button for adjusting the video signal
strength. The audio function enable users to switch among 2/4
media sources and enjoy the output on one display and one set of
speakers.
Installation is as easy as connecting USB A-B cables to
computers and to the unit. Computer selecting is as easy as
front panel button pressing. The built-in USB hub ensures
smooth switching from one computer to the other. The
CL-KVM-DAAG-112/ CL-KVM-DAAG-114 provides the easiest
way to manage multiple computers with USB interface and share
USB peripherals among computers. No more tangled cables and
messy working environment; let the CL-KVM-DAAG-112/
CL-KVM-DAAG-114 do the computer switching for you.

--------------- System Requirements
Console side
One DVI monitor
One USB keyboard
One USB mouse
Computer side
Each USB-enabled computer must be connected to the unit by
One DVI cable for monitor, as shown below.
One USB A-B cable with Type-A and Type-B plug for USB
devices.
Or one DVI 2-to-2 cable for monitor+ USB devices as shown

----------------- Installation
PC BIOS Notice
The following BIOS setup changes are necessary for PC users
and not necessary for Mac users:
1. In STANDARD CMOS, set HALT ON ERROR to ALL BUT
KEYBOARD.
2. In PNPAND PCI SETUP, set PNP OS INSTALLED to YES and
set USB IRQ to ENABLED.
Note: The CL-KVM-DAAG-112/ CL-KVM-DAAG-114 is applicable
for USB keyboard and mouse switching from one computer
to the other. If you plan to share other peripherals such as
a CCD camera, printer or scanner, it is required to shut
down the driver of the computer before switching to another
computer. Because port switching is equivalent to
unplugging the USB cable from one computer and plugging
it to another one, some USB drivers check attached USB
peripherals all the time and do not accept plug-n-play
function.
