ATEN CS-104U User Manual

USER'S MANUAL

Please read this manual thoroughly and follow the installation and operation procedures carefully to prevent any damage to the CS-104U and/or any devices it connects to.

This package contains:

• CS-104U

• User Mauual

Printed in Taiwan 09/1999 All brand names and trademarks are the registered property of their respective owners.

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.

Overview

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.

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.

Installation

Before you begin, make sure that power to all the devices you will be connecting up (Master View CS-104U, the monitor, and the connected computers) have been turned off.

1. Plug the monitor, keyboard, and mouse into the Console port connectors of the Master View CS-104U unit.

2. If you choose to use an external 5V power adapter, plug the adapter into an AC source, then plug the adapter cable into the unit's Power Jack.

3. Use the video extender cables to connect the CS-104U's video ports to the video ports on the corresponding computers, as shown in the diagram below.

4. Use standard USB cables to connect from the CS-104U's USB ports (B connector) to the USB ports on the corresponding computers (A connector), as shown in the diagram below.

5. Power on all devices.

DC 5V

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.

Operation

Manual Port Selection

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.

Auto Scan Mode

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.

• To invoke Auto Scan Mode, simply press the Auto Scan button (located on the Master View's front panel), In. The Auto Scan LED flashes to indicate that Auto Scan Mode is in effect.

• To turn Auto Scan Mode Off, press the Auto Scan button again, to pop the button out. The Auto Scan LED stops flashing when Auto Scan Mode is no longer in effect.

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.
