Introduction
Overview
The CS-228 KVM Switch is a control unit that allows two independent
keyboard, mouse, and monitor consoles to access eight computers, either
independently or on a multi-user shared basis. A CS-228 can control up to 8
computers directly. By cascading it down to a CS-138A, CS-9138, CS-128A,
or CS-124A, up to 9 units (the CS-228 plus eight cascaded ones), can control
up to 64 computers.
Setup is fast and easy - plugging cables into their appropriate ports is all that
is entailed. There are no installation routines or complex software programs
to configure. Because the CS-228 intercepts keyboard input directly, it works
on most hardware platforms and with most operating systems.
The CS-228 provides a convenient OSD (On Screen Display) function that
allows either of the two consoles to access any computer connected to the
system by means of an on screen, menu-driven interface. A powerful Quick
View Scan feature allows auto scanning and monitoring of the activities of all
operating computers on the installation one-by-one.
For security, two level password protection (administrator and user), prevents
unauthorized access to the computers. Responding to the growing use of
audio input/output in the workstation space, the CS-228 has been designed
with built in microphone and speaker support, as well.
There is no better way to save time and money than with a CS-228
installation. By allowing all the computers to be managed from two separate
consoles, a CS-228 installation: (1) eliminates the expense of having to
purchase a separate keyboard, monitor, and mouse 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 around from one computer to another, while
allowing a single user to access the computers from several different
convenient locations, or for two users to share them.

Two Stage Installation
To control even more computers, up to eight additional switches can be
cascaded from the CPU ports of the CS-228. The cascaded switches that
connect back to the First Stage unit (the CS-228), are considered Second
Stage units. As many as 64 computers can be controlled in a complete two
stage installation. A table showing the relation between the number of
computers and the number of switches needed to control them is provided in
the Appendix.
Note: 1. Only CS-138A, CS-9138, CS-128A, or CS-124A units can be used
with the CS-228;
2. The CS-228 does not support cascading beyond the second stage.
To set up a two stage installation, refer to the diagram on the next page and

1. Make sure that power to all the devices you will be connecting up has
been turned off (unplug the power cords of any computers that have the
Keyboard Power On function).
2. Follow steps 1 and 2 under Single Stage Installation (see p. 9).
3. Use a PS/2 KVM cable (described in the Cables section, p. 4) to connect
any available CPU port on the CS-228 to the console port on the Second
Stage unit.
Repeat step 3 for any additional switches that you wish to cascade.
4. Use PS/2 KVM cables (described in the Cables section, p. 4) to connect
any available CPU port(s) on the Second Stage unit(s) to the monitor,
keyboard and mouse ports of the computer(s) you are installing.
5. Plug in the power adapter cables for all switches on the installation.

Basic Operation
Hot Plugging
The CS-228 supports hot plugging - components can be removed and added
back into the installation by unplugging their cables from the CPU ports
without the need to shut the unit down. In order for hot plugging to work
properly, however, these procedures must be followed:
1. When hot plugging cables from the CPU ports the cable must be plugged
back into the same port it was removed from.
2. You may unplug the mouse and plug it back in again (to reset the mouse,
for example), as long as you use the same mouse.
If there is no response to the mouse and/or keyboard after you plug the
mouse back in, perform a K/M Reset. To do so, insert a thin pointed object
into the Reset receptacle on the unit’s front panel and gently push.

Powering Off and Restarting
If it becomes necessary to Power Off the CS-228, before restarting it you
must do the following:
1. Shut down all the computers on the CS-228 installation (includes those
connected to cascaded switches).
Note: You must unplug the power cords of any computers that have the
Keyboard Power On function. Otherwise, the switches will still
receive power from the computers.
2. Wait 10 seconds, and then restart the CS-228.
Note: When the CS-228 comes up it issues a long beep, and the
Consoles are automatically logged out. Each Console logout
produces a short beep - so you will hear one long and two short
beeps.
3. Restart the Second Stage switches.
4. After all the switches are up, power On the computers.
Port Selection
Instant access to any computer on the installation is provided by the menu
driven On Screen Display (OSD) function. OSD operation is discussed in the

OSD Operation
OSD Overview
The On Screen Display (OSD) provides a menu driven interface to handle
the computer switching procedure. All operations start from the OSD Main
Menu. To activate the Main Menu, tap a [Ctrl] key twice.
Note: 1. You must tap the same key twice (both left, or both right).
2. If using the [Ctrl] key conflicts with applications running on the
computers, you can change the OSD activation key to the Scroll
Lock key (see OSD Activating Hotkey under the F6 Set function on
p. 23), in which case you would press [Scroll Lock] twice.
When you invoke the OSD, a screen similar to the one below appears:
! The OSD always starts in List view, with the highlight bar at the same
position it was in the last time it was closed.
! The Port Number (PN) for each computer on the installation is shown in
the left column of the list. Port numbering details are discussed in the next
section.

Port Numbering
The Port Number (PN) for a computer connected to the CS-228 is derived
from the KVM Port (1 - 8) on the CS-228’s back panel that the computer is
connected to. A computer connected to KVM Port 7, for example, would
have a PN of 7.
A computer connected to a cascaded CS-228 has a two digit PN. The first
digit represents the KVM Port of the CS-228 (the First Stage unit) that the
Second Stage CS-228 is cascaded down from; the second digit represents the
KVM Port of the Second Stage CS-228 that the computer is connected to.
For example, a computer connected to KVM Port 3 of a CS-228 that is
cascaded down from KVM Port 2 of a CS-228, would have a PN of 2-3.
OSD Main Menu Headings
Heading Explanation
PN
This column lists the Port Numbers for all the KVM Ports. The simplest
method to access a particular computer (assuming you know which
port it is attached to), is to double-click it with the mouse; or to use the
navigation keys to move the highlight bar to it, and then press
[Enter] .
Indicates ports that this Console can access.
QV
An arrowhead symbol in this column indicates the Port has been
selected for Quick View Scan Mode (see F7, p. 25).
PC
A sun symbol in this column indicates that the computer connected to
this Port is powered On, and is On Line.
NAME
If a port has been given a name (see F2, p. 19), its name appears in

OSD Navigation
! To dismiss the menu, and deactivate the OSD, Click the X at the upper
right corner of the OSD Window; or press [Esc].
! To move up or down through the list one line at a time, Click the Up and
Down Triangle symbols (
!"), or use the Up and Down Arrow Keys. If
there are more items than appear on the screen, the screen will scroll.
! To move up or down through the list one screen at a time, Click the Up
and Down Arrow symbols ("#), or use the [Pg Up] and [Pg Dn] keys. If
there are more items than appear on the screen, the screen will scroll.
! To access a port, double-click it (or move the highlight bar to it), and then
press [Enter].
Note: 1. If you try to access a computer that has been designated as
private (see Private Mode, p. 24), a message appears to inform
you that the Port is in Private Mode. In this case, the screen is
blank, and the port can neither be viewed nor accessed.
2. If you try to access a computer that is already being accessed
by another Console, a message displays to inform you that the
Port is In Use. The target computer’s screen can be viewed, but
you cannot give it any input until the Console that already has
control stops accessing it.
3. In a cascaded installation, if a computer attached to a Second
Stage unit is already being accessed by the other Console, that
computer and all the other computers attached to the same
Second Stage unit are considered to be in use. None of them
can be viewed or accessed from your Console. This is so,
because accessing any one computer attached to a Second
Stage unit ties up the entire CS-228 Port that their Second Stage
unit is cascaded down from. Only after the original Console no
longer has access can these computers be controlled from the
other Console.
! After executing any action, you automatically go back to the menu one
level above.

F4 SCAN
Clicking the F4 field, or pressing [F4] initiates Scan Mode, in which the OSD
cycles through all the ports that have been selected for scanning with the Scan
Mode setting (see p. 24). When you want to stop at a particular location, press
the [Spacebar] to stop scanning.
Note: 1. If the scanning stops on an empty port, or one where the computer
is attached but is powered Off, the monitor screen will be blank and
the mouse and keyboard will have no effect. To recover, press the
OSD Activation Hotkey.
2. As the OSD cycles through the selected ports, an S appears in front
of each accessed computer’s Port ID display to indicate that the
computer is being accessed under Quick View Scanning.
3. If a particular port is being accessed by another Console, an R
appears in front of the Port ID display to indicate that the Port is
"View Only." It can be viewed, but cannot be accessed at this time.
4. If a particular port has been designated as private (see F6 on p. 23),
a P appears in front of the Port ID display to indicate that the Port
is in "Private Mode." The screen is blank, and the port can neither
be viewed nor accessed.
5. If a particular port was accessed by one of the Consoles, but is no
longer being accessed, the OSD begins a Timeout countdown (see
Set Access Timeout p. 22), a Z appears in front of the Port ID
display to indicate that the Port is Pending (i.e., the original
Console that accessed can still reclaim it, but if it doesn’t access the
Port before the Timeout period ends, it is up for grabs to the first
comer).
