Safety Instructions
General
Read all of these instructions. Save them for future reference.
Follow all warnings and instructions marked on the device.
Do not place the device on any unstable surface (cart, stand, table, etc.). If
the device falls, serious damage will result.
Do not use the device near water.
Do not place the device near, or over, radiators or heat registers.
The device cabinet is provided with slots and openings to allow for
adequate ventilation. To ensure reliable operation, and to protect against
overheating, these openings must never be blocked or covered.
The device should never be placed on a soft surface (bed, sofa, rug, etc.) as
this will block its ventilation openings. Likewise, the device should not be
placed in a built in enclosure unless adequate ventilation has been
provided.
Never spill liquid of any kind on the device.
Unplug the device from the wall outlet before cleaning. Do not use liquid
or aerosol cleaners. Use a damp cloth for cleaning.
The device should be operated from the type of power source indicated on
the marking label. If you are not sure of the type of power available,
consult your dealer or local power company.
The device is equipped with a 3-wire grounding type plug. This is a safety
feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not attempt to defeat the
purpose of the grounding-type plug. Always follow your local/national
wiring codes.
Do not allow anything to rest on the power cord or cables. Route the
power cord and cables so that they cannot be stepped on or tripped over.
If an extension cord is used with this device make sure that the total of the
ampere ratings of all products used on this cord does not exceed the
extension cord ampere rating. Make sure that the total of all products
plugged into the wall outlet does not exceed 15 amperes.
To help protect your system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
un-interruptible power supply (UPS).
Position system cables and power cables carefully; Be sure that nothing
rests on any cables.

CS-1742 / CS-1744 User Manual

When connecting or disconnecting power to hot-pluggable power
supplies, observe the following guidelines:
Install the power supply before connecting the power cable to the
power supply.
Unplug the power cable before removing the power supply.
If the system has multiple sources of power, disconnect power from the
system by unplugging all power cables from the power supplies.
Never push objects of any kind into or through cabinet slots. They may
touch dangerous voltage points or short out parts resulting in a risk of fire
or electrical shock.
Do not attempt to service the device yourself. Refer all servicing to
qualified service personnel.
If the following conditions occur, unplug the device from the wall outlet
and bring it to qualified service personnel for repair.
The power cord or plug has become damaged or frayed.
Liquid has been spilled into the device.
The device has been exposed to rain or water.
The device has been dropped, or the cabinet has been damaged.
The device exhibits a distinct change in performance, indicating a need
for service.
The device does not operate normally when the operating instructions
are followed.
Only adjust those controls that are covered in the operating instructions.
Improper adjustment of other controls may result in damage that will
require extensive work by a qualified technician to repair.

Rack Mounting
Before working on the rack, make sure that the stabilizers are secured to
the rack, extended to the floor, and that the full weight of the rack rests on
the floor. Install front and side stabilizers on a single rack or front
stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the
rack first.
Make sure that the rack is level and stable before extending a device from
the rack.
Use caution when pressing the device rail release latches and sliding a
device into or out of a rack; the slide rails can pinch your fingers.
After a device is inserted into the rack, carefully extend the rail into a
locking position, and then slide the device into the rack.
Do not overload the AC supply branch circuit that provides power to the
rack. The total rack load should not exceed 80 percent of the branch circuit
rating.
Ensure that proper airflow is provided to devices in the rack.
Do not step on or stand on any device when servicing other devices in a
rack.

Introduction
Overview
The Master View Dual-View CS-1742 or CS-1744 USB KVM Switch brings
dual head video functionality to ATEN's USB KVM switch technology. Now,
two (CS-1742) or four (CS-1744) dual head computers can be accessed and
controlled from a single console that consists of a USB keyboard, USB mouse,
and two VGA, SVGA, or Multisync monitors.
In addition, the CS-1742 / CS-1744 incorporates a two port USB hub that
allows each of the computers to share any USB peripherals connected to the
hub on a one computer at a time basis. Recognizing the importance of sound,
the switches are also audio enabled. A single microphone can provide audio
input to each of the computers, and you can listen to the audio output of each
computer on a single set of speakers (on a one-at-a-time basis).
The CS-1742 / CS-1744's independent (asynchronous) switching feature
allows independent switching of the KVM, USB hub, and audio focus. If you
wish, you can give one computer the KVM console focus, anotherthe USB hub
focus, while a third has the audio focus.
Setup is fast and easy; simply plug cables into their appropriate ports. There is
no software to configure, no installation routines, and no incompatibility
problems. Since the CS-1742 / CS-1744 intercepts keyboard input directly, it
works on multiple operating platforms (PC compatible, Mac and Sun).
There are two convenient methods to access the computers: push button port
selection switches located on the unit's front panel; and hotkey combinations
entered from the keyboard.
Since a single console manages all of the computers, the CS-1742 / CS-1744
setup: 1) eliminates the expense of having to purchase separate peripheral
components for each computer; 2) saves all the space those extra components
would take up; 3) saves on energy costs; and 4) eliminates the inconvenience
and wasted effort involved in constantly moving from one computer to another.
