ETHERNET
100 m Ethernet interface. When needing to work on LAN, one of these 4 ports
(both the Ethernet ports of Transmitter and Receiver) should be used for Internet
access and the others can be connected with computers. If they are well-
connected, the yellow LED indicators on the corresponding ports will keep
blinking and the green ones will stay on when working.

DC 24V
Connect with DC 24V / 1.25A power adaptor (Not necessary if Receiver connects
with power).
TWISTED PAIR CABLE DESCRIPTION
The twisted pair used for this unit MUST be a straight-through cable.
NOTE: The cable connectors MUST be metal, and the shielded layer of the cable MUST be connected to the
connector’s metal shell to make a better transmission.

SYSTEM CONNECTION
USAGE PRECAUTIONS
1. The system should be installed in a clean environment with the proper temperature and humidity.
2. All of the power switches, plugs, sockets, and power cords should be insulated and safe.
3. All devices must be connected before the power is turned on.
4. Use shielded straight-through CAT5e / CAT6a cable with TIA / EIA T568B terminations for good
transmission effect.
CONNECTION PROCEDURES
1. Connect the HDMI®source (like a DVD Player) to the HDMI®IN port of the Transmitter using an HDMI®
cable.
2. Connect the HDBT OUT port of the Transmitter and the HDBT IN port of the Receiver using a single
CAT5e / CAT6a cable.
3. Connect the HDMI®display (like an HDTV) to the HDMI®OUT of the Receiver using an HDMI®cable.
4. Both the Transmitter and the Receiver have IR IN and IR OUT ports. When one model is used as an IR
signal Receiver, the IR signal must be sent out by the other model. For example: When the “IR IN” of
the Receiver connects with an IR Receiver, the IR Emitter must be connected to the “IR OUT” of the
Transmitter.
5. To set as a LAN device, one of the four Ethernet ports of the Transmitter and the Receiver should be
used for Internet access, and the others can be connected to computers.
6. Connect the RS232 port of the computer and the RS232 port of the Transmitter/Receiver (either one
should work since the RS232 signal can be transmitted bi-directionally) using an RS232 cable.
7. Connect with DC 24V power adapter(s) separately or only connect the power adapter to the
Transmitter or the Receiver.
