transmitting over the network, use an Ethernet Switch between Transmitter and
Receiver.
5.
If the configuration is a point-to-multipoint or multipoint-to-multipoint:
5a.
You will need to use an Ethernet Switch with Gigabit ports and DHCP Server support.
In addition Jumbo Frame support is required, and IGMP Protocol support is required for
the multipoint-to-multipoint case.
Verify that the Ethernet Switch is configured
correctly and that the DHCP Server is enabled, that the IGMP Protocol is enabled
for multipoint-to-multipoint applications, and that Jumbo Frames is enabled
. See
the operating manual for more information about configuring the Ethernet Switch.
5b.
Connect all Transmitters and Receivers to the Ethernet Switch.
5c.
Use the DIP Switches to select a unique Device ID for each Transmitter present on the
network and configure each Receiver Device ID to the corresponding selected
Transmitter.
Note
: This step is not necessary if the MuxLab Pro Digital Network Controller
(500811) is used.
6.
Powering the Transmitter or Receiver via an external power supply is only necessary where
PoE (PSE) is unavailable. If PoE is unavailable, connect the 5 VDC power supply (sold
separately) to each Receiver and to an AC power outlet. Next connect each Transmitter in the
same manner. If power is present, the green power LED on each Transmitter and Receiver
will illuminate.
Note: Power ‘ON’ the Video Wall 4K over IP PoE Extender only after all connections
have been made.
7.
Power ‘ON’ the HDMI equipment and verify the image quality.
8.
This product supports IR pass-thru control. If infrared remote control is needed to control the
Source equipment from the Display, connect the IR Sensor (sold separately) to the 3.5mm
Stereo Jack of the Receiver and the IR Emitter (sold separately) to the 3.5mm Mono Jack of
the Transmitter.
Note: You can differentiate the IR Sensor and the IR Emitter by looking at the 3.5 mm
plug. The IR Sensor is using a Stereo Plug (3 Contacts) and the IR Emitter a
mono plug (2 Contacts).
9.
Position the IR Sensor so that it is directed at the hand-held remote control. For a clear IR
signal reception, aim the hand-held remote control at the top of the IR Sensor enclosure.
10.
Position the IR Emitter as close as possible to the source’s IR Sensor (i.e. DVD player). For a
clear IR signal reception, the IR Emitter can be glued on the source’s IR Sensor. The IR
Emitter’s signal is transmitted from the side of the enclosure.
11.
This product supports RS232 bidirectional communication. On the Transmitter, the RS232
port is configured as a DCE; and on the Receiver as a DTE. Please connect your RS232 cable
accordingly. Configure the RS232 communications setting via the device web interface.
12.
Commands or messages may be sent via RS232 by connecting a PC to the RS232 port of the
Video Wall 4K over IP PoE Extender, or over the network via IP. This communications is
meant to be machine to machine.
