NTI VEEMUX DVI VIDEO MATRIX SWITCH
42
Notes:
1. A Blu-Ray player, and any other video source with protected content, must use "Direct" DDC option and can be
connected to only one output port at a time.
2. In order for the video sources to correctly receive the EDID information from the switch at boot-up, the switch must
be powered-up before all attached video sources.
3. If “Disable Toggle HP” is checked for any Input port, the changes made for that port will not take immediate effect
when “Save” is pressed.
Hot Plug Options
The DVI video standard includes the ability for the DVI monitor to automatically send EDID information to the video source when
the DVI cable is disconnected and re-connected, or “Hot Plugged”.
The DDC Options page includes the option to maintain a “monitor connected” signal to the video source to prevent the source
from going to sleep if the display device is actually disconnected from the VEEMUX. To maintain this signal, place a checkmark in
the box for “
Keep HP On
” for the associated Input Port (Figure 24).
Under normal circumstances, a PC that is powered-ON without having an active (output with display attached) DVI output port
connection would switch to the default output mode (normally VGA) because the PC would not detect the presence of a DVI
display. This can be avoided by checking “Keep HP On” for that Input port. This allows the switch to signal the PC as if a DVI
display was connected triggering the PC to output video on its DVI output.
The DDC Option page also provides the option to maintain a “monitor connected” signal when the VEEMUX is scanning from one
display device to another. Normally the “monitor connected” signal would toggle from On to Off and back to On when the
VEEMUX switches from display device to the next. To prevent this toggling and maintain the signal as On, place a checkmark in
the “
Disable Toggle HP
” for the associated Input Port (Figure 24).
Note: If the “Disable Toggle HP” is checked for an Input port and the EDID information source for an Input port is
switched from one display or source to another, the Input port will not update the EDID information from the new
display/source.
DDC Mix
From the Administration menu, the DDC Mix page can be displayed. DDC Mix provides a means to decide which outputs
(displays) will be used to provide EDID information to the selected input. The VEEMUX will compare EDID information from all
selected outputs and provide EDID information that is common to those displays to the video source. If the “Mixed” option is
desired for an input on the “DDC Options” page (page 41), settings of the DDC Mix for that input (below) should be selected and
saved first.
If the DDC Mix configuration for an input is not configured and the “Mixed” option for the input is selected on the DDC Options
page, a minimal default collection of EDID information will be provided to the video source.

To save time and use the EDID information from the same
outputs for all inputs (video sources), make the output
selections above and then click on “Save For All Inputs”.
Select the Input port that will receive EDID information
common to the outputs (displays) selected below.
