EDID Learning Explained

The Display Data Channel (DDC) is a digital connection
between a computer display and a graphics adapter
that allows the display to communicate its specifications
to the adapter.

The Extended Display Identification Data (EDID) is a
data structure provided by a computer display over the
DDC to describe its capabilities to a graphics card.

The DVS400 does not continue the DDC across the
CAT6 links and contains its own EDID at the video
source input. Therefore, the EDID on the DVS400 is
used in place of the actual monitor’s EDID. In order for
the computer to output at the correct resolutions and
refresh rates for a specific monitor, the DVS400 must be
loaded with the monitor’s EDID.

On power-up the DVS400 reads and stores the EDID
of the DVI monitor connected to the local loopback
port. If the local loopback port is disconnected during

power-up, the stored EDID will not be modified.

Installation

1. Turn off computer and monitor.

2. Connect DVI male to male cable between the
computer and the transmitter.

3. Connect monitor or projector to the local loopback
DVI port on the transmitter.

4. Turn on the monitor.

5. Plug in one of the power transformers and
connect it to the transmitter.

6. Remove the monitor from the local loopback
DVI port on the transmitter and connect it
to the DVI port on the receiver.

7. Connect a shielded CAT6 cable between port 1
on the transmitter and port 1 on the receiver.

8. Plug in the other power transformer and connect
it to the receiver.

9. Turn on the computer.
