Introduction

The KMS4 is a keyboard multiplexer with onboard multiple keyboard system interfaces. One

keyboard can communicate with up to 4 different systems, and the user controls system
selection by programmable soft macros. Keyboard mapping is provided between the different
keyboard types so the user can choose which ever keyboard is preferred.

Mouse protocols are handled in the same way, with support for Microsoft, PS/2, DEC, Sun and
Apple.

I - Tips for Set up

DO NOT CONNECT KMS4 TO ITS INTENDED COMPUTERS WITHOUT FIRST POWERING
DOWN THE COMPUTERS.

Follow the 10 steps for installation starting at Page 5 of this manual.
Once a mouse is connected to the KMS4, and the KMS4 is connected to the its attached

computers, it is necessary to program the KMS4 ( Step 10).
Each KMS4 channel and the KMS4 input device type must be programmed. This is required so

that the KMS4 can correctly interpret the input data and so that the KMS4 can re-map the data,
and service the appropriate electrical interface for the attached computers.

WHEN A KMS4 IS REDEPLOYED OR DIFFERENT SETUP INSTALLED, REPROGRAMMING
MAY BE REQUIRED.

The programming procedure requires the KMS4 to be powered and attached to the actual type
of keyboard and mouse that will be used. The programme set up is stored in non-volatile RAM
and will not be lost when the KMS4 is powered off.

See Page 8 of the manual to set up keyboard/mouse type and channel settings.

Overview

To change the keyboard and mouse type, or when the input device is not set up.
Hold the front panel push-button for more than 8 seconds then push/release the button rapidly
4 times. A channel light will start to flash quickly.

The input device is selected by repeatedly pressing the front panel button while in this mode.
Channel 1 light: PS/2 keyboard, PS/2 mouse
Channel 3 light: Sun keyboard & mouse
Channel 4 light: Apple keyboard and mouse or Apple Keyboard & PS/2 mouse

All other settings should not be used, including any combinations of lights which are for
reserved modes.

Once the channel number is set to suit the keyboard and mouse Type R to reset the KMS4.
Note: Resetting the KMS4 will disable any PS/2 mouse connections - the PS/2 will require a
warm boot to re-enable the mouse.

The KMS4 will automatically leave programming mode if a key is not pressed for 35 seconds or
10 seconds after a key is pressed.

Once the keyboard and mouse type is set - use the keyboard to set other options.
( Refer to Page 8 of the manual)

To enter program mode 0 with the keyboard/ mouse type set up.
Hold down the front panel push button and strike the TAB key on the keyboard. Note you

cannot change the input keyboard/mouse type if you entered program Mode 0 in this way.
The quickest way to set the KMS4 is to select one of the Single key overall setups listed on

page 9 of the manual.

II - Safety Warning

In order for the KMS4 to comply with the requirements of EN60950, the following points MUST
be complied with:

1) Do not connect KMS4 to any device that will impair the SELV (safety - extra low voltage)

integrity of the system. Do not connect the KMS4 to any device capable of generating
hazardous voltages on the keyboard, mouse or RS232 port.

2) Only use cables provided by Access Keyboards.

3) Only use power supply provided by Access Keyboards.

4) The maximum total rated load drawn by the keyboard & mouse must not exceed the stated

maximum on the rating label. This applies to the devices connected to inputs 1, 2 and 3,
EXT LED and the SUN K/M port together. The KMS104 external lightbar draws 8mA max.

5) Check the KMS4 rating label.

6) Only use fuses supplied.

7) Do not use the external power supply if the KMS4 is powered by the computers. The unlikely

event of a power supply fault may go undetected. You can test your system by removing the
power supply while all computers are on, if the KMS4 continues to operate, do not replace
the power supply.

8) Ensure the mains socket outlet for the power supply (if used) is near the equipment and

remains easily accessible.

9) No user-serviceable parts inside the KMS4 and power supply. Hazardous voltages are

present in the power supplies.

The EU declaration of conformity is available on request.

FCC Notice (Applies to KMS4s labelled with the FCC conformance notice)
USA only

This equipment has been tested and complies with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the interference
at his own expense.

A Notice About Cables: Use only cables supplied by Access Keyboards for connecting any
device to the KMS4 to reduce the possibility of interference with Radio and Television reception.
