Check the protocol
Check whether the proper protocol is selected (see section 7.1 about Changing
and viewing protocols on page 48 ). Select Protocol #1 in order to use the matrix
with the controller software.
Check alive connections
Only one connection is allowed simultaneously. Check whether there is another
open connection (e.g. opened router web interface, running control software over
Ethernet). Try restarting the router if you have no other option.
9.4. Picture is not displayed or distorted
Check the cables
Due to the high data rates, the cables must fit very well. DVI connectors have to be
locked with screws, no tensions or breaches are allowed. If your source or display
has more connectors then make sure that the proper interface is selected.
Since this matrix switcher provides no input equalization, only standard length
(max. 5 meter) DVI cables can be used. Always use high quality DVI cable for
connecting sources and displays.
Although the router is equipped with DVI-I connectors, analog signals are not
supported. You cannot use VGA cables with DVI-VGA adapter plugs.
If you want to route dual link signals, check if the cables are capable of this. See
section
2.3.1 About Dual link signals on page 15 for more information.
Check the crosspoint matrix
Check the connection between the input and output port either on the front panel or
from web or the control software. Check whether the output is muted or not.
Check EDID related problems
Maybe your display device is not capable of receiving the sent video format. Try
emulating your display device
‟s EDID to the source. You will find help on this
process in section 4.4.1 about EDID Router operation with control software on
page 33 , or in section 5.4.1 about EDID Router operation with built-in website on
page 43 . If you get a picture now, you have an EDID related issue, please read
section 1.5 about Understanding EDID on page 11 for more details.
Check the source
Check whether your source is powered on and configured properly. The HDMI
output can be turned off on most DVD players. If the source is a computer, then
verify that the DVI output is selected and active. Try restarting your computer; if
you get a picture during the booting process, you have to review the driver settings.
The router is not HDCP compliant; therefore encrypted sources will not work.
