ADDERLink Gold Manual

							AdderLinkInstallation and UsePage 30Mouse restoration functions should be used with care as unpredictableresults may occur if the wrong mouse type is selected. If in doubt restore themouse by powering down the PC normally.Standard PS/2 mouse data uses a different data format to IntelliMouse data and so
two reset functions are provided on the AdderLink. The type of data format expected
by the PC depends upon the driver and the type of mouse that was connected when
the driver was booted. The following table may be used as a guide.
Note that the mouse reset functions predict the likely mouse resolution settings but
may not restore the speed or sensitivity of the mouse exactly as they were when the
PC originally booted.

							AdderLinkInstallation and UsePage 313. Using the AdderLinkThis section explains the general operation of the AdderLink. We recommend that
you read this section before starting to use the product.
3.1 Power on status
The AdderLink is ready for use as soon as the XR receiver and XL transmitter have
been powered on. Remember that the XL transmitter usually draws its power from
the computer via the keyboard cable and the XR unit draws its power form the
supplied power adapter.
If a security password has not been set then the AdderLink XR unit will power on
and immediately establish a link to the remote computer attached to the XL unit. On
the AdderLink this is indicated by the activity light illuminating and on the AdderLink
Gold this is indicated by the remote (1) light illuminating.
If a security password has been set then the AdderLink XR unit will only illuminate
the power light on the XR unit and will not display any video. The AdderLink will
indicate that it is waiting for a password to be entered by alternately illuminating the
num and scroll lock lights and then the caps lock light on the keyboard attached to
the XR receiver unit.
The AdderLink XL unit draws its power from the attached CPU via the keyboard
cable. The green power light confirms that there is sufficient power available. If the
power light flashes or is off continuously then there is not sufficient power available.

							AdderLinkInstallation and UsePage 343.3 Keyboard NUM, CAPS and SCROLL lock indicators
The AdderLink uses the keyboard NUM, CAPS and SCROLL lock lights to indicate
various operating conditions as follows:
NUM, CAPS and SCROLL lock lights flash in sequence
The AdderLink flashes the NUM, CAPS and SCROLL lock lights in sequence on the
keyboard connected to the XR unit to indicate that the AdderLink is in video
compensation / configuration mode. The NUM lock light comes on first with CAPS
and SCROLL off. Then the CAPS lock comes on with NUM and SCROLL off and
finally the SCROLL lock comes on with NUM and CAPS off. The rate of flashing
indicates the level of video compensation applied by the video compensation
amplifiers. A slow flash rate indicates a small amount of compensation (short twisted
pair cable distance).  A fast flash rate indicates a greater level of video
compensation for longer cables.
NUM, CAPS and SCROLL lock lights flash together
The AdderLink Gold flashes the NUM, CAPS and SCROLL lock light together on the
keyboard attached to the XL unit or the keyboard attached to the XR unit to indicate
that the other keyboard currently has control of the computer connected to the XL
unit.  These lights will stop flashing when a timeout has occurred and the computer
connected to the XL unit is free for use by either keyboard/mouse set. 
						

							AdderLinkInstallation and UsePage 35NUM and SCROLL lock flash alternately with CAPS lock
The AdderLink alternately flashes NUM and SCROLL lock and then CAPS lock on
the keyboard attached to the XR unit to indicate that the AdderLink is currently
locked and is awaiting a password to be entered by the user to unlock the
AdderLink.
3.4 Keyboard hotkey control
AdderLink XR unit may be set to respond to various keyboard hotkey combinations.
These keyboard hotkeys are selected using the option switches on the side of the
AdderLink XR unit (see section 2.7). Keyboard hotkeys may be used to switch off
the video, lock the AdderLink and enter video compensation / configuration mode.
On the AdderLink Gold the keyboard hotkeys are also used to select between the
remote (1) and local (2) computers.
All of the hotkey control commands are invoked by holding down the two hotkeys
and then pressing a command key. By default, the two hotkeys are ‘CTRL’ and
‘ALT’, although other combinations can be selected by reconfiguring the hotkeys
(see section 2.7). Once the hotkey command has been activated you will need to
release the hotkeys and the command key before a new hotkey command is
accepted by the AdderLink. HOTKEYs + TAB is an exception and this allows you to
tab through the ports by holding down the hotkeys and repeatedly pressing TAB.
The hotkey commands are summarised below (IMPORTANT NOTE: the numbers
on the numeric keypad do not form part of a valid hotkey) :
 ‘HOTKEYs’ and ‘0’ – switches off the video signal and all the associated red status
lights on the XR unit and disconnects the keyboard and mouse from the computer
that they are currently controlling. This will cause some monitors to go into standby
mode or switch off. The video signal can be re-enabled by selecting a computer
using ‘HOTKEYs’ and ‘TAB’ or ‘HOTKEYs’ and ‘1’ (or ‘HOTKEYs’ and ‘2’ on the
AdderLink Gold) . 
						

							AdderLinkInstallation and UsePage 36‘HOTKEYs’ and ‘L’ - Disconnects the AdderLink XR’s keyboard and mouse from
the computer that they are controlling and switches off all the red status lights. The
video signal is switched off. If a password has not been set then the AdderLink can
be re-enabled by selecting a computer using ‘HOTKEYs’ and ‘TAB’ or ‘HOTKEYs’
and ‘1’ (or ‘HOTKEYs’ and ‘2’ on the AdderLink Gold). If a password has been set
then the AdderLink will alternately flash the NUM and SCROLL and then the CAPS
lock lights on the keyboard connected to the XR unit. This indicates that a valid
password must be entered to unlock the AdderLink. Simply type the same key
combination as was set during configuration (see section 3.10) followed by the
RETURN key. Note - if anyone has typed at the keyboard whilst in secure mode, it
will be necessary to type RETURN first to clear the invalid password, then type the
valid password followed by RETURN again.
‘HOTKEYs’ and ‘1’ - selects the remote computer attached to the XL unit
‘HOTKEYs’ and ‘2’ - selects the local computer attached to the XR unit (AdderLink
Gold only)
‘HOTKEYs’ and ‘TAB’ – Selects the next computer (remote or local)
‘HOTKEYs’ and RETURN – Enters video compensation / configuration mode
Examples of common hotkey sequences (assuming CTRL + ALT hotkey option):
To lock the AdderLink
pressba ba
L Lrelease L Lba ba
To tab through computers (AdderLink Gold):
pressba ba
 v v
 release v v
 pressv v
release v v
 pressv v
release vba vba 
						

							AdderLinkInstallation and UsePage 373.5 Contending for control of the XL units computer (AdderLink
Gold)
Timeout mode
On the AdderLink Gold, the computer attached to the XL unit may be accessed by
the control port (Keyboard/Monitor/Mouse/Speakers/Microphone) on the XL unit or
the control port on the XR unit. Only one control port may be active at any one time.
As soon as keyboard or mouse activity is detected on a control port then this
becomes the active control port. Keyboard, mouse or microphone activity on the
inactive control port will have no effect on the XLs computer until no keyboard or
mouse activity has been detected on the active control port for the timeout period.
The timeout period is selected using option switches 7 and 8 on the XL unit (see
section 2.6). The video is broadcast to both monitors if option switch 6 is in the OFF
position or just to the active control ports monitor if option switch 6 is in the ON
position (see section 2.6).
Exclusive use mode
The control port on the XL unit may obtain exclusive use of the XL units computer
upon demand. To gain exclusive use, the operator uses the following hotkey
combinations. Note that these hotkeys are only applicable to the keyboard
connected to the XL unit. When exclusive use has been set the video picture from
the XL units computer will not be sent to the XR unit even if broadcast mode has
been selected.
‘HOTKEYs’ and ‘1’ - Gains exclusive use of the computer attached to the XL unit
‘HOTKEYs’ and ‘0’ - Relinquishes exclusive use of the computer attached to the XL
unit.
3.6 Entering and exiting video compensation / configuration mode
The AdderLink’s video compensation and user selectable options and functions are
accessed in compensation / configuration mode. To enter this mode press the
selected hotkey combination together with the RETURN key and to exit this mode
press the RETURN key again. For example: 
						

							AdderLinkInstallation and UsePage 38To enter compensation / configuration mode:
pressba ba
f   f  release f fba ba
To exit compensation / configuration mode:
pressf f  release f f
3.7 Mouse control
On the AdderLink Gold XR unit, the computers can conveniently be selected using a
three button mouse or IntelliMouse. In order to switch to the other computer simply
hold down the central mouse button or wheel button and click on the left hand
mouse button. The other computer will then be selected. In order to use this feature
you must enable it using the M2 option in configuration mode (see section 4.2).
3.8 Stereo audio support on the AdderLink Gold
You may connect stereo speakers to both the AdderLink Gold XL unit and the
AdderLink Gold XR unit. Audio from the computer connected to the XL unit is
broadcasted to the speakers attached to the XL unit and to the XR unit. The
speakers on the XR unit will output the audio signal from the XL unit if the remote
computer (1) is selected or the audio from the computer connected to the XR unit if
the local computer (2) is selected.
The AdderLink transfers the audio speaker signals between the XL and XR units by
multiplexing the audio signals onto the video signals. A small degree of audio noise
is introduced by this process. The effect of this noise may be reduced by the
following actions:
· Set the speaker output volume on the PC connected to the XL unit to the highest
setting available.
· Adjust speaker volume control knob away from the maximum setting.
· Do not boost the audio BASS signal if this can be avoided.
The AdderLink is designed to carry audio signals with a maximum peak-to-peak
voltage of 5 volts. This is suitable for most PC audio outputs. If you are sending 
						

							AdderLinkInstallation and UsePage 39audio with a higher peak-to-peak value than 5 volts this may affect the video picture
causing temporary loss of the picture during peak audio output. If you are
transferring such an audio signal then reduce the PC’s maximum output volume
setting until the picture remains fully stable.
3.9 Microphone support on the AdderLink Gold
You may connect a microphone to both the AdderLink Gold XL unit and the
AdderLink Gold XR unit. The computer attached to the XL unit will take its
microphone input from the last active user port. So, if the keyboard and mouse on
the XR unit were last used to control the computer then the microphone signal will
be taken from the XR unit. Alternatively if the keyboard and mouse connected to the
XL unit were the last to control the computer then the microphone signal will come
from the microphone attached to the XL unit.
If the local computer (2) is selected on the XR unit then, as expected, its microphone
signal will be taken from the microphone attached to the XR unit.
The AdderLink transfers the audio microphone signals between the XR and XL units
by multiplexing the audio signals onto the video signals. A degree of audio noise is
introduced by this process. The effect of this noise may be reduced by setting the
microphone audio input volume on the PC connected to the XL unit to the lowest
practical setting.
3.10 Setting and using the security password
There are many situations where unrestricted access to computers or sensitive
information needs to be controlled. In such circumstances, the AdderLink XL unit
may be locked away in a room or secure cabinet and the computer may be
controlled remotely from the XR unit.
The AdderLink incorporates a security password system that enables the XR unit to
be locked so that the secure computer cannot be controlled.  Once a password has
been set the AdderLink XR unit may be disabled by pressing the hotkeys together
with the L (lock) key. The XR unit may only then be unlocked by entering the
password. For example if the hotkeys are set to CTRL and ALT then pressing the
following key combination would cause the AdderLink XR unit to lock.
