Quick Installation Guide

Overview
The HDMI / RS232 Extender Kit (500454 or 500454-POE) allows HDMI equipment to
be connected up to 230 ft (70 m) @ 1080p via one (1) Cat 5e/6 unshielded twisted pair
cable in a point-to-point configuration. The 500454 includes one (1) Transmitter and
one (1) Receiver as well as an IR Emitter (500998) and IR Sensor (500999) for remote
control applications. The 500454-POE comes with one (1) power supply, as it does not
require a power supply on the receiver side. The 500454-RX or 500454-POE-RX
receivers are used in conjunction with MuxLab’s HDMI Matrix Switch. For installation
instructions, please refer to the HDMI Matrix Switch Installation Guide.

Applications

Applications include digital signage, commercial and residential AV systems, classroom
projector systems, boardroom systems, collaborative PC systems, and medical
information systems.

Installation

1. Identify the connectors on the Transmitter and Receiver as indicated on the

product end panels.

2. Verify that the distance between the HDMI Transmitter and Receiver is within

MuxLab specifications (see specifications table).

3. To install the Transmitter:

3a. Connect the Transmitter to the HDMI video source with an HDMI compliant

cable.

3b. Connect one (1) length of Cat 5e/6 (or higher) grade UTP cable to the

RJ45 LINK connector on the Transmitter.

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.
