Overview
The Master View CS-124A 4 Port KVM (Keyboard, Video, Mouse),
Switch is a control unit that allows access to four computer systems
from a single PS/2 keyboard, PS/2 mouse, and monitor console in a
cost effective manner. There are three convenient methods to access
the computers: (1) push button port selection switches; (2) Hotkey
combinations; and (3) a Foot Switch (optional). 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-124A intercepts keyboard input directly, it works on any
hardware platform and with all operating systems.
There is no better way to save time and money than with a Master View
CS-124A installation. Since a single console manages all of the
computers, the CS-124A setup: eliminates the expense of having to
purchase a separate keyboard, monitor, and mouse for each computer;
saves all the space those extra components would take up; saves on
energy costs; and eliminates the inconvenience and wasted effort
involved in constantly moving around from one computer to another.

* See the note under Cables in the next section.
Cables
Use of substandard cables may damage the connected devices or
degrade overall performance. For optimum signal integrity and to
simplify the layout, we strongly recommend that you use the following
ATEN high quality CS Custom Cable sets: 2L-1001P/C (1.8 m) and
2L-1003P/C (3 m).
Note: 1. If your computer uses a standard AT style keyboard socket
you will need to purchase a PS/2-to-AT keyboard adapter
(Part No. 2A-106, or any standard keyboard adapter).
2. If your computer uses a 9 pin serial port, you will need a
special PS/2-to-Serial mouse adapter (Part No. 2A-105); a
standard mouse adapter will probably not work.

1. On Line and Selected LEDs:
M When an On Line LED is lit, it indicates that the computer at-
tached to the corresponding port is up and running.
M When a Selected LED is lit, it indicates that the port it corre-
sponds to is the currently selected port. Depending on the port’s
status, the LED may flash according to a specific pattern (see the
LED Display table in the Appendix for details).
2. Port Selection Switches
M Press a switch to access the PC attached to the corresponding
port.
M K/M Reset: If the keyboard and mouse get stuck and need to be
reset, simultaneously press this Port1 / Port2 switch combination
for three seconds.
3. Auto Scan Switch
M Press this switch to activate Auto Scanning. To stop, press it
again, or press the keyboard’s Spacebar.
M Auto Scan Mode can also be invoked by simultaneously pressing
the Port3 / Port4 switch combination for five seconds.
M The amount of time it dwells on each port is determined with seg-
ments 1 and 2 of the Master View CS-124A’s DIP Switch (located at the left of the rear panel). See the table in the Appendix

1. Power Jack
The CS-124A is designed to be non-powered (external power is not
required - its operation power comes from the computers). In
general, the only time that external power is required is when you
daisy chain it, or if operation becomes erratic because the unit isn’t
obtaining enough power from the computer connections. If you
choose to use external power, the power adapter cable plugs in
here.
2. DIP Switch
Switches 1 and 2 select the Scan Time; Switch 3 selects the Hotkey
Combination; Switch 4 selects the operation type for Last/Next
Mode. See DIP Switch Settings in the Appendix for details.
3. Console Port Section
M If this is a first station unit, your monitor, keyboard and mouse
plug in here.
M If this is a daisy chained unit, the cables that link back to a port
on a higher Master View unit plug in here.
4. CPU Port Section
The extender cables that connect the unit’s monitor, keyboard and
mouse ports to the computer’s monitor, keyboard and mouse ports
plug in here.
5. Optional Foot Switch Connector
If you are using an optional foot switch, its cable plugs in here.
