4.3.1 Video/Graphic Mode
Press the EDID button on the KDS-EN2R to toggle between the Video mode and
the Graphic mode. The selection is immediately saved to flash memory and is
saved to the non-volatile memory after rebooting the unit. In the:
•Video Mode, the FW automatically trades off the bandwidth with higher
video quality to ensure a smooth video playing experience
•Graphic Mode, the FW fixes the trade-off to ensure the best possible
graphic/text viewing experience
4.3.2 Anti Dither
Press and hold (for 3 sec) the EDID button on the KDS-EN2R to cycle between
the anti-dithering modes (1 bit, 2 bit or Off).
Dithering introduces random noise to the signal that creates a half-tone effect so
that the output image appears smoother. Dithering creates a problem for low
bandwidth video compression even for a static source display.
To overcome the dithering problem, set the anti dither (EDID) button to 1bit or 2
bit. Set to Off if the source content does not generate a dithered output.
4.3.3 Update EDID
The KDS-EN2T is shipped with a factory default EDID. We recommend updating
this EDID to that of the acceptor connected to the KDS-EN2R.This EDID update
ensures optimum performance according to the output resolution of the connected
HDMI acceptor.
To manually update the EDID:
1. Connect the new HDMI acceptor to the KDS-EN2R.
2. Press and hold the EDID button (for about 6 to 8 sec) on the KDS-EN2Rto
update the EDID.
The EDID is updated and stored on the KDS-EN2T.
Note that in a multicast setup (see Section 5.2
i
) it is important to
update the EDID while the HDMI acceptor with the lowest resolution
is connected. Once the update is complete, this EDID information
will be saved to the non-volatile memory of the KDS-EN2T.

4.3.4 Reset to Factory Default + FW Update
Press and hold (for 6 to 8 sec) the MODE button on the KDS-EN2T/KDS-EN2R to
reset to the factory default and upgrade the firmware.
You can upgrade the firmware via the Web Pages or the IP HDMI Utility program
(see Section 6.4.1.2
Firmware update file name will be: Transmitter: webfwh.bin; Receiver: webfwc.bin
).
4.4 Setting the Multicast Group ID
When hosts and clients are assigned the same multicast group ID number, all the
clients in the group will decode the stream from the same host. You can set up to
16 groups either via the GROUP ID DIP-switches or the IP-HDMI Utility software
(see Section 6.2
). For example, to set the group ID to 1, you have to set DIP 1, 2
and 3 to OFF and DIP 4 to ON.
The application software group ID setup overrides the DIP-switch
group ID setup.

5 Connecting the KDS-EN2T/KDS-EN2R
You can set the KDS-EN2T/KDS-EN2R units in various configurations. For
example:
•A single transmitter/receiver setup (see Section 5.1
•A Multicasting setup (see
)
Section 5.2
•A video wall setup (see
)
Section 5.3
5.1 KDS-EN2T/KDS-EN2R Transmitter Receiver Setup
)
You can use the KDS-EN2T HDMI to IP Transmitter (see Section 4.1) and the
KDS-EN2R to configure an HDMI-to-IP Transmitter and Receiver system (see Figure
4).
Always switch off the power to each device before connecting it to your
KDS-EN2T/KDS-EN2R. After connecting your KDS-EN2T/KDS-EN2R,
connect its power and then switch on the power to each device.
To connect the HDMI-to-IP transmitter and receiver system as shown in the example
in Figure 4, do the following:
1. On the KDS-EN2T,connect an HDMI source (for example, the HDMI output
from a media player) to the HDMI IN connector.
2. On the KDS-EN2R, connect the HDMI OUT connector to an HDMI acceptor
(for example, a projector).
3. Connect the LAN RJ-45 connector on the KDS-EN2T to the LAN RJ-45
connector on the KDS-EN2R using an Ethernet cable.
4. On both the KDS-EN2T and the KDS-EN2R, connect the 5V DC power
adapter to the power socket and connect the adapter to the mains electricity
(not shown in Figure 4).
5. If required, connect a PC and/or controller to the RS-232 9-pin D-sub
Connector (see Section 5.4
i
) to control the HDMI acceptor, for example.

5.2 Multicasting Setup
In the multicasting setup, one host (transmitter) and multiple clients (receivers)
share the same group ID (see Section 4.4 and 6.2Section
The multicast addresses used range from 255.0.0.XXX to 255.0.1.XXX, where
XXX stands for the group ID as set by the DIP switch (see
), so that all of the
clients decode the same stream (encoded by the host), without creating additional
load on the network.
Section 4.4
The example illustrated in
).
Figure 5 shows a multicast setup including one host
connected to several clients sharing the same group ID. The host transmits the
HDMI and RS-232 content to all the clients that share its group ID; other clients
that are connected to the same Ethernet switch will not receive this content. Other
hosts, with different group IDs can co-exist in the system (for example, a video
wall setup, see Section 5.3).

14 KDS-EN2T, KDS-EN2R - Connecting the KDS-EN2T/KDS-EN2R
Figure 5: Multicasting Application
An additional KDS-EN2T host can be connected to the Ethernet switch and set to
group ID 4. This host can transmit HDMI and RS-232 content to KDS-EN2R
clients that are also set to group ID 4.

5.3 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).

16 KDS-EN2T, KDS-EN2R - Connecting the KDS-EN2T/KDS-EN2R
5. Connect the 9-pin D-sub Y-cable to the three KDS-EN2T units, as illustrated
in Figure 6.
Figure 6: Connecting the RS-232 Y-cable
6. Set the group ID via the DIP-switches. For example, set the group ID of the:
KDS-EN2T transmitting to the first row and the receivers positioned in
the first row to 1
KDS-EN2T transmitting to the second row and the receivers positioned
in the second row to 2
KDS-EN2T transmitting to the third row and the receivers positioned in
the third row to 3
7. If required, on each unit connect the 5V DC power adapter to the power
socket and connect the adapter to the mains electricity (not shown in Figure
7)
8. Set the wall application for each unit via the IP HDMI Utility software and/or
Web pages (see Section 6
9. Reboot all devices. Ensure that all remote displays and all network cables
are connected correctly (a video source is required at this step).
).
