Video Wall Setup
A video wall consists of several screens that are tiled together to form one very
large display.
The video wall configuration consists of one or more transmitters that connect to a
series of receivers that make up the video wall. Each display is connected to the
output of one receiver. Usually a video wall setup would include several
transmitters (one dedicated transmitter per row).
Using a single transmitter for a video wall will usually result in lower video quality
and tearing.
The
KDS-EN2T
and
KDS-EN2R
units are each defined by their location in the
video wall layout. Each
KDS-EN2T
is assigned a row number and defined by row
number and position in the row. The position definition is unique and is usually
defined once during the basic setup.
To
simplify the video wall configuration process, the first host of the first row of the
video wall is assigned to be the control portal. The control portal controls the other
transmitters and receivers in the setup via the RS-232 closed loop chain (see
Figure 6
). The RS-232 chain lets transmitters communicate with each other even if
they are not part of the same LAN.
To configure a video wall (for example, a 3x3 video wall), do the following:
1. Connect an HDMI source (for example, a media player) to the INPUT of a
distribution amplifier (for example, the Kramer
VM-4Hxl
, 1:4 HDMI
Distribution Amplifier).
2. On the distribution amplifier, connect the outputs (for example, three outputs
on the Kramer
VM-4Hxl
) to the HDMI IN connectors of three
KDS-EN2T
units, respectively.
3. Connect the LAN RJ-45 connector on each
KDS-EN2T
unit to the input
RJ-45 connector on an Ethernet switch.
4. Connect the output RJ-45 connectors on the Ethernet switch to nine
KDS-EN2R
units (each
KDS-EN2T
unit connected to the Ethernet Switch,
distributes the signal to three
KDS-EN2R
units).
