3. System Connection
3.1 Usage Precautions
System should be installed in a clean environment and has a prop temperature and
humidity.
All of the power switches, plugs, sockets and power cords should be insulated and
safety.
All devices should be connected before power on.
Use shielded straight-thru CAT5e/CAT6a cable with TIA/EIA T568B terminations for
good transmission effect.
3.2 System Diagram
3.3 Connection Procedure
Step1. Connect HDMI source (such as DVD player) to HDMI IN port of the transmitter
with HDMI cable.
Step2. Connect HDBT OUT port of transmitter and HDBT IN port of receiver with single
CAT5e/CAT6a cable.
Step3. Connect HDMI displayer (such as HDTV) to HDMI OUT port of receiver with
HDMI cable.
Step4. Both transmitter and receiver have IR IN and OUT. When one model use for IR
signal receiver, the IR signal must be sent out by the other model.
For example: When “IR IN” of receiver connects with an IR receiver, the IR
5
Ultra-thin HDBaseT Extender
Emitter must be connected to “IR OUT” of transmitter.
Step5. To set as a LAN, one of the four ETHERNET ports of transmitter and receiver
should be used for Internet access, and the others can be connected with
computers.
Step6. Connect the RS232 port of the computer and the RS232 port of transmitter or
receiver (any one is able to work as the RS232 signal can be transmitted
bi-directionally) by using a RS232 cable.
Step7. Connect with DC24V power adaptor(s) separately or only connect power adaptor
to transmitter or receiver.
