							AdderLinkInstallation and UsePage 142. Installation2.1 What you will need  A category 5 (or better) twisted pair cable of the required length to connect the
AdderLink XL and XR units together. These cables contain 4 pairs of twisted
wires. Specifications and recommended cable types are given in appendix A.
AdderLink supports cable lengths up to 200 metres. Structured wiring within
buildings may also be used together with suitable patch cables but the number of
cable connections should be kept to a minimum to maximise signal quality.  Cables to connect the AdderLink XL unit to your computer. Cable specifications
are given in appendix A. Cable packs are available for the AdderLink if you do not
wish to purchase individual cables. You do not need to connect cables for devices
that you do not wish to use with the exception of the keyboard cable which the
AdderLink XL unit uses to draw power from the computer. If you do not wish to
connect a keyboard then you may alternatively purchase an optional power
adapter (part code: PSU-IEC-5V DC)  A monitor with a standard VGA/SVGA (15 pin) connector that will work when
connected directly to your computer. If you are connecting an additional computer
to the AdderLink Gold XR unit then the monitor must also work when connected
directly to this computer. AdderLink supports low and high resolution monitors.  A standard AT or PS/2 style keyboard. If you are using an AT keyboard with a 5
pin connector you may connect this to the AdderLink using a standard AT to PS/2
keyboard adapter.  A PS/2 style two or three button Microsoft  
or Logitech  
compatible mouse or a
Microsoft IntelliMouse compatible mouse. If you have an AdderLink Gold and you
wish to use the mouse to switch the XR unit’s channel then you will need a three
button mouse or an IntelliMouse.
(The AdderLink supports ‘Internet Mice’ that are compatible with the Microsoft
IntelliMouse. These are fitted with a wheel or other scroll control and sometimes
have additional buttons. Examples are: Microsoft IntelliMouse, Logitech Pilot
Mouse+, Logitech MouseMan+, Genius NetMouse and Genius NetMouse Pro.) 
						

							AdderLinkInstallation and UsePage 15  A suitable mouse driver for your PC(s). Supported types are:
- PS/2 or RS232 two button mouse driver (any manufacturer).
- Microsoft mouse driver (including IntelliMouse).
- Logitech mouse driver (including two button, three button and wheel mouse)
If you have the AdderLink Gold then you may also require:  An additional set of computer cables to connect your additional computer to the
AdderLink Gold XR unit.  An additional keyboard, mouse and monitor of the type described above to
connect to the AdderLink XL unit.  One or two sets of stereo speakers.  One or two microphones.
If you require to connect serial devices you may also require:  Suitable conversion cables to connect your particular type of RS232 device.
Refer to appendix A for more details.
Use of PS/2 and RS232 style mice with the AdderLink - The mouse connections
from AdderLink to PCs support either a PS/2 or an RS232 mouse. AdderLink
automatically converts from the PS/2 mouse commands to RS232 serial mouse
commands. Serial mice types are selected by using an adapter as described in
Appendix A. The 9-pin D-type serial ports on the AdderLink may also be configured
to support serial mice but this setup is less ideal and is therefore not generally
recommended. The AdderLink will operate without a mouse connected if you do not
wish to use one. 
						

							AdderLinkInstallation and UsePage 162.2 Mounting the AdderLink
The AdderLink has been designed to be used either on a desktop or mounted in a
19 inch rack. If the AdderLink is to be mounted in a 19 inch rack then you will need
the optional rack mounting kit (part code: RMK-AL). The AdderLink may also be
mounted on a suitable vertical surface, such as the side of a desk, with the use of
strong Velcro strips.
2.3 Connecting your devices
Ensure that the power adapter is disconnected from the AdderLink and that all the
devices which are to be attached are switched off. Connect your devices to the
AdderLink or AdderLink Gold as shown in figures 4 and 5. Ensure that the cables
are no longer then the maximum cable lengths specified in appendix A. Any unused
computer or peripheral connections can be left unconnected. To connect computers
with serial mouse connections and AT style keyboard connections use the adapters
supplied in the cabling pack as shown below. Alternatively, if you have chosen not to
purchase the cable pack, refer to appendix A for cable specifications.The AdderLink is now ready for use and will start to operate as soon the XL and XR
units are both powered on. There is no requirement to switch the AdderLink units on
in any defined order. The AdderLink XL unit normally draws its power from the
connected computer via the keyboard cable. However, if you are connecting to a
computer using cables that are longer than 3 metres or are connecting to a lower
powered device, such as some types of keyboard/video/mouse switch, the optional
power adapter may be required. When using the optional power adapter, ensure
that it is connected to the mains and powering the AdderLink before you switch on
the connected computers. Under these circumstances, failure to switch the
AdderLink and computers on in the correct order can lead to the mouse and/or
keyboard not being recognised by the computers when they are switched on.

							AdderLinkInstallation and UsePage 192.4 Configuring your PC(s)
Configure your PC in the same way that you would if your keyboard, mouse,
speakers, microphone and monitor were all connected directly to your PC, but
bearing in mind the following points:  AdderLink emulates Microsoft compatible serial, IntelliMouse and PS/2 mice, so
ensure that your PC software is configured for a Microsoft mouse of the correct
type. Refer to the list of supported drivers in section 2.1.  AdderLink supports VGA/SVGA/XGA/XGA2 type monitors, but does not support
the automatic detection features available with some ‘plug and play’ monitors
and video cards. If you have this type of video card and monitor, you should
select the video mode manually instead of relying upon the automatic detection
feature.  The sound quality of the AdderLink Gold’s audio speaker channels is maximised
by setting the maximum possible audio output level from your PC. You can then
adjust the speaker volume to suit.  The sound quality of the AdderLink Gold’s audio microphone channels is
maximised by setting the minimum possible audio input level to your PC.
2.5 Configuring the AdderLink
The AdderLink is supplied in a default state that is suitable for most applications
except that the video compensation needs to be adjusted to match the
characteristics of the twisted pair cable. The video only needs to be compensated
once during setup as the compensation value is stored by the AdderLink and
retained even when the power is off.
The AdderLink is configured using the following:
1. Option switches (see section 2.7)
The option switches on the side of the AdderLink select the keyboard hotkey
combination that is used to access video compensation / configuration mode. They
also control some other hardware related functions.
