2.6 Configuring the AdderView DVI
IMPORTANT NOTE
Some DVI video cards need to communicate with a monitor before they will
output a video signal. This communication normally occurs within the first 5
seconds after the computer has been powered on. The computer can only
communicate with the monitor if it is the currently selected computer. If you
have this type of DVI video card you will need to select the computer before
switching the computer on. To make this process easy for you we have built
an auto-switch function into the AdderView DVI. With the auto-switch function
enabled the AdderView will automatically switch to a computer when the
computer is powered on. When powering on several computers you should
power them on in sequence, waiting a few seconds between each one to allow
the video card to communicate with the monitor.
• To enable the auto-scan function move switch 1 on the underside of the
AdderView DVI to the ON position.
• To disable the auto-scan function move switch 1 on the underside of the
AdderView DVI to the OFF position.
The AdderView DVI is supplied pre-configured with factory defaults which are
suitable for most applications. There are a number of more advanced options which
can be set by the user. These are stored in the AdderView DVI's EEPROM memory
and are retained when the power is disconnected.
The options may be changed whilst the AdderView DVI is in configure mode. You
may enter configure mode at initial power on or whilst the AdderView DVI is running:
To enter configure mode at power on:
Switch off all the attached PCs and the AdderView DVI. Hold down the front panel
key whilst powering on the AdderView DVI. Remember that the AdderView DVI
draws its power from any attached PC via the keyboard cable and so will power
itself on when the attached PC is switched on or when the optional power adapter is
connected. Do not release the key until the AdderView DVI displays 'C' to show that
it has entered configure mode.
