Troubleshooting
6.1. USB connection problems
Check the cable and software settings
Check whether your USB cable is properly connected. In most cases there are
more COM ports present in the operating system. Please verify the connection
settings of your software. The DA2DVI-Pro's virtual COM port communicates with
9600 Baud, 8 data bit, No parity, 1 stop bit.
6.2. There is no picture
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.
Check the incoming signal
Check the Source Connected LED on the front panel of the DA2DVI-Pro. This LED
indicates the presence of the +5V signal coming from the DVI source. If it is not
illuminated, then your DVI source is not working properly. Please refer to the user's
manual of your DVI source.
Check the Signal Present LED on the front panel of the DA2DVI-Pro. This LED
indicates the presence of an active incoming DVI clock signal. If it is not
illuminated, then no DVI clock signal is present at the input connector of the
DA2DVI-Pro. Please check whether your source is configured to output a video
signal.
Run the control software and check whether a video signal is present at the input
or not. If there is a video signal, then the input port number I1 has an orange
background. If I1 has a white background, then there is no video signal, please
continue at chapter 6.3.
Check the outgoing signal
Check the Monitor Hotplug 1/2 LED on the front panel of the DA2DVI-Pro. This
LED indicates the presence of the Hotplug signal coming from the attached display
device. If it is not illuminated, then your display is not powered or not configured
properly.
Right click on the output number in the crosspoint area (O1 or O2) to open the DVI
output settings window in the control software. Try reloading factory default settings
to the output. If it doesn't help, then try adjusting the different settings. You will find
help for this in section 1.1.
Check EDID related problems
Check the EDID Status LED on the front panel of the DA2DVI-Pro. This LED
indicates whether a valid EDID is selected. If it is illuminated RED, then an invalid
EDID or an empty memory address is selected. Please select a valid EDID.
If the EDID Status LED is illuminated GREEN, then 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 to this process in section 1.1. If you get a
picture now, you have an EDID related issue, please read chapter 1.3 for more
details.
