4. To install the Receiver:
4a. Connect the Receiver to the HDMI display equipment with an HDMI compliant
cable.
Note: When used with MuxLab’s HDMI Matrix Switch, please consult the Matrix
Switch Installation Guide.
4b. Connect one (1) Cat 5e/6 cable to RJ45 LINK connector on the Receiver.
5. Connect the 5 VDC power supply to the Receiver first, and then plug the power
supply into an AC power outlet. Connect the 5 VDC power supply to the
Transmitter first, and then plug the power supply into an AC power outlet. If power
is present, the green power LED of the Transmitter and the Receiver will be ON.
Note: Power-up the HDMI / RS232 Extender only after all connections are made.
6. Power-up the HDMI equipment and verify the image quality.
7. This product support 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).
8. 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.
9. 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 may be affixed to the
source’s IR Sensor. The IR Emitter’s signal is transmitted from the side of the
enclosure.
10. 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.
11. The 500454 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.
12. The following diagram shows the final configuration.
