Hardware Installation

1. Power off all devices including your HDMI source and HDMI display(s).
2. Connect your HDMI source device to the Transmitter’s HDMI In connector with an HDMI cable (HDMI cable is not included).
3. Connect your CAT cables between the Transmitter and CAT6/7 Receivers.
4. Optional: Connect an HDMI display to the HDMI Out connector of the Transmitter using an HDMI cable (HDMI cable not included). This connection is needed only if you require local monitoring of the HDMI signal.
5. Connect an HDMI display to each CAT6/7 Receiver’s HDMI Out connector with an HDMI cable (HDMI cables not included).
6. Optional: Connect the IR Receiver cables and the IR Emitter cable to the IR interface ports. This connection is needed only if you need to control your HDMI devices from the remote location. See IR Control, starting on page 11, for proper IR connection.
7. Plug the included 12V/2A power adapter into the Transmitter’s Power Jack and 5V/500mA power adapter into the Receiver’s Power Jack, then plug the power adapters into a reliable power outlet.
8. Power on your HDMI source device and HDMI display(s). The Splitter/Extender is ready for use.

The application diagram shows the most typical input and output devices used with the Splitter/Extender.

Figure 4: Application Diagram

CAT Cable Wiring

We suggest both RJ-45 connectors be wired identically using T568B wiring standard for the best performance and compatibility.

Both connectors must be wired identically, to T568B standard.

Note: You may use CATSe, CAT6 wiring, however, for best performance CAT6a or CAT7 (particularly in electrically noisy environments) is recommended. The maximum transmission distance and video quality may be compromised by cable quality, patch cables, poor termination, wall plates, cable kinks, and electrical interference. We recommend using 100% copper 23AWG (avoid CCA type) CAT cable, in one straight run (avoid/minimize patches) and avoid close proximity to electrical sources.

IR Control

Provides IR control of the connected devices. The IR feature is bi-directional so either the source device or the display device(s) can be remotely controlled.

Controlling the Source Device

1. Connect an IR Emitter Cable to the IR Out port of the Transmitter.
2. Point the IR Emitter Cable’s IR eye in line with the source device’s IR window.
3. Connect an IR Receiver Cable to the IR In port on each CAT6/7 Receiver.

Note: The Transmitter’s IR Out connector will output the IR signals received from any of the CAT 6/7 Receivers, so as to allow control of a source from any of the remote CAT 6/7 Receivers.

Controlling the Display Device(s) using IR In

Allows you to remotely control each display individually.

1. Connect an IR Receiver Cable to the IR In port of the Transmitter.
2. Connect an IR Emitter Cable to the IR Out port on each CAT6/7 Receiver.
3. Point the IR Emitter Cable’s IR eye in line with the display’s IR window.

FAQ & Troubleshooting

Q: Poor video quality or no video signal on display:

A1: Check whether the HDMI cables are connected properly and are in good working condition.
A2: Make sure the resolution of the display is compatible with the splitter’s resolution

Q: No HDMI signal output from the CAT6/7 connectors while the local HDMI out port is working normally:

A1: Check whether the HDMI cables are connected properly and are in good working condition.
A2: Press the reset button on both TX and RX and reconnect.

Q: Snowy or fuzzy screen on the displays:

A1: Cause by damaged or low quality HDMI cables. Change to a higher quality HDMI cable. Make sure the cable length is less than or equal to 5 meters.
A2: Try another CAT cable and make sure the cable length is within the specified range.
