LINK connector on the Receiver.
5.
Place the rear switch in the “Normal” position on the Transmitter and Receiver.
6.
This kit supports PoC, allowing the Transmitter to power the Receiver, or the
Receiver to power the Transmitter. Connect the 12VDC power supply to either the
Receiver or Transmitter first, and then plug the power supply into an AC power
outlet. If power is present, the blue power LED of the Transmitter and the
Receiver will be ON.
Note: Power-up the HDMI/RS232 Extender Kit, HDBT, 4K/60 only after all
connections are made.
7.
Power-up the HDMI equipment and verify the image quality.
8.
This product supports bi-directional IR control. If infrared remote control is needed
to control the Source equipment from the Display, connect the IR Sensor to the
3.5mm Stereo Jack of the Receiver and the IR Emitter to the 3.5mm Mono Jack of
the Transmitter.
Note: The IR Sensor can be distinguished from the IR Emitter by looking at the
3.5-mm plug. The IR Sensor has a 3.5mm stereo plug (3 Contacts) and the
IR Emitter has a 3.5mm mono plug (2 Contacts).
9.
Position the IR Sensor so that it is aimed toward the hand-held remote control. For
clear IR signal reception, aim the hand-held remote control toward 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,
Blu-ray, or media player). For a clear IR signal reception, the IR Emitter may be
affixed to the source’s IR Sensor. The IR Emitter’s signal is transmitted from the
side of the enclosure.
11.
If infrared remote control is needed to control the Display equipment from the
Source, connect the IR Emitter to the Receiver’s 3.5mm stereo jack and connect the
IR Sensor to the Transmitter’s 3.5mm mono jack.
12.
The 500459 also supports RS232 pass-thru in order to allows a device such as
commercial monitors to be controlled as in digital signage application. Please refer
to the following diagram for the cabling connection.
13.
Note that the unit firmware may be updated via the RS232 port, if a new version is
available. To do so, download both the new firmware and special loader software
from the MuxLab website (if available). Place the rear switch in the “Service”
position, and run the loader software to complete the upgrade by following the on
screen instructions. Once done, return the rear switch to the “Normal” position.
