Note: 1. For PC users, since you are using a USB
Keyboard and/or Mouse, make the
following changes to your CMOS Setup
program (see the on screen instructions
at bootup for how to enter the CMOS
Setup program):
a) In STANDARD CMOS, set HALT ON
ERROR to ALL BUT KEYBOARD
b) In PNP AND PCI SETUP, set PNP OS
INSTALLED to YES; set USB IRQ to
ENABLED
(Mac users do not have to do this.)
2. The drivers for most USB devices (CCD
Cameras, Scanners, Printers, e.g.), are
required to be shut down before you
disconnect the device, or else the
system may crash. When you switch
computers with the Port Selection
Switch, it is the equivalent of
disconnecting the device. Therefore, if
you have peripheral devices (other than
a second keyboard and mouse)
connected to these ports, you must be
sure to shut down the USB drivers for
them before switching computers.
USER'S MANUAL

Overview
Features
The Master view CS-104U represents a revolutionary new
direction in KVM Switches: a dual function 4 Port KVM Switch / 2
Port USB Hub control unit. The CS-104U incorporates USB
technology to handle the data connection between itself and the
connected computers, and to provide two USB ports for peripheral
devices that the connected computers can share.
• Dual Function KVM / USB Switch - Two Switches In One
• Controls 4 Computers From a Single Console Over a USB
Connection Using Standard USB Cables
• Simultaneous Reverse Operation - 4 Computers Can Share 2
USB Peripheral Devices
• Eliminates Driver Conflict Between the Console's Mouse and
the Computers' Configuration
• Notebooks Can Use the Console's Mouse and Keyboard At the
Same Time
• Easy to Install - No Software Required - Standard Cables to
Connect to the Computers Is All It Takes
• Easy to Operate - Computer Selection Via Push Button Switch
• Auto Scan Function to Monitor Computer Operation
• LED Display For Easy Status Monitoring
• Saves Time, Space, Power, and Equipment Costs
• Supports DDC2 (Display Data Channel)
• Hot Pluggable
As a KVM switch, the CS-104U allows access to four computer
systems from a single console (keyboard, mouse, and monitor)
utilizing the USB connection for the keyboard and mouse. At the
same time, it allows the four PCs and/or Macs to utilize the USB
port connection to access two USB peripheral devices (printers,
scanners, modems, etc.), on a `one computer at a time' basis.
Installation and operation are as easy as can be. Simply connect
the cables. The computers will recognize the USB peripherals the
first time they come in contact with them and automatically
install the necessary drivers. There is no other software
installation necessary. You select the active computer (that the
console controls and has access to the USB peripheral devices), by
simply pressing an electronic pushbutton switch on the unit's
right panel.
Before the development of the Master View, the only way to
control multiple computer configurations from a single console
was through a complex and costly network system. Now, with the
Master View CS-104U, you can easily access up to four computers
and two USB peripheral devices in a cost effective manner.
There is no better way to save time and money than with a Master
View CS-104U installation. By allowing a single console to
manage all of the attached computers and USB peripherals, the
Master View CS-104U eliminates the expense of purchasing
separate keyboards, monitors, mice, and peripherals for each
system. Moreover, it saves all 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.
System Requirements
Console
• One VGA, SVGA, or Multisync monitor capable of the highest
resolution that you will be using on any computer in the
installation
• One USB Mouse
• One USB Keyboard
Computer
The following equipment must be installed on each computer that
is to be connected to the system:
• PC with Windows 98 or Mac (G3 or iMac)
• USB Host Controller installed on the system.
• A VGA, SVGA or Multisync card.
Note: A DB 15 to HDB 15 VGA adapter (purchased separately),
is required in order to connect a Mac to the CS-104U.

3. Scan Time Selection Switch
This slide switch selects the amount of time the CS-104U
dwells on each port (3 seconds, or 15 seconds), when Auto Scan
Mode is in effect.
4. USB Ports for the Console Mouse and Keyboard, and USB
peripheral devices
Plug the peripherals into any of the ports.
Note: The drivers for most USB devices (CCD Cameras,
Scanners, Printers, e.g.), are required to be shut down
before you disconnect the device, or else the system may
crash. When you switch computers with the Port Selection
Switch, it is the equivalent of disconnecting the device.
Therefore, if you have peripheral devices (other than a
second keyboard and mouse) connected to these ports, you
must be sure to shut down the USB drivers for them before
switching computers.

Auto Scan Mode
Manual Port Selection
The Master View CS-104U's Auto Scan feature automatically
switches among the four computers at regular intervals (3 or 15
seconds), so that you can monitor their activity without having to
take the trouble of switching yourself.
Controlling the computers in your Master View CS-104U
installation from a single console could not be easier. Simply
keep pressing the Port Selection button on the Master View's
right panel until the computer you wish to access becomes the
selected one.
Note: The drivers for most USB devices (CCD Cameras,
Scanners, Printers, e.g.), are required to be shut down
before you disconnect the device, or else the system may
crash. When you switch computers with the Port Selection
Switch, it is the equivalent of disconnecting the device.
Therefore, if you have peripheral devices (other than a
second keyboard and mouse) connected to the CS-104U's
USB peripheral ports, you must be sure to shut down the
USB drivers for them before switching computers.
Note: The CS-104U's Power On default is to link to Port 1. If the
computer attached to Port 1 is inactive, the monitor will be
blank so it may appear as if the unit is not functioning.
This is not the case. Simply press the Port Selection
Switch (located on the unit's right panel), to switch to an
active computer on one of the other ports.
Note: 1. While Auto Scan Mode is in effect, neither the
keyboard nor the mouse will function. You must turn off
Auto Scan Mode in order to be able to use the console.
2.The drivers for most USB devices (CCD Cameras,
Scanners, Printers, e.g.), are required to be shut down
before you disconnect the device, or else the system may
crash. When the computers switch under Auto Scan
Mode, it is the equivalent of disconnecting the device.
Therefore, if you have peripheral devices (other than a
second keyboard and mouse) connected to the CS-104U's
USB peripheral ports, you must be sure that the USB
drivers for them are shut down on all machines before
invoking Auto Scan Mode.
Troubleshooting
Note: If you are experiencing problems, first make sure that there
are no problems with the cables, and that they are all
properly connected.
