Hardware Installation

1. Power off all devices including your HDMI source(s) and HDMI display(s).
2. Connect your HDMI source device(s) to the 2×4 HDMI 2.0 Splitter/Extender’s HDMI Input connector(s) with HDMI cable(s) (HDMI cables not included).
3. Connect your CAT cables between the Splitter/ Extender and CAT 6/7 Receivers.
4. Optional: Connect an HDMI display to the HDMI Output connector of the Splitter/Extender 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 CAT 6/7 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 power adapter into the Splitter/ Extender ‘s Power Jack, then plug the power adapter into a reliable power outlet. Note: The CAT 6/7 Receivers do not need power adapters, they can be powered from the Splitter/Extender over CAT cable with PoC technology.
8. Power on your HDMI source device(s) and HDMI display(s). The Splitter/Extender is ready for use.

Application Diagram

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 cat5e. cat6 UTP (cat6 preferred) in conjunction with the HDEfeseT output: however for best performance use cat6a or cat7 (particularly in electrically noisy environments). The maximum distances & transmission performance for HDMI and HOST may be compromised by cable quality. patch panels. poor termination. wall plates. cable kinks and electrical interferences. Generally ensure the cat cable is solid copper core of 23AWG (avoid CCA type), in one straight run (avoid/minimise patches) and avoid close proximity to any noisy electrical sources.

Source Device Switching

Manual Switching

Press the Select button to switch to the next source device, the corressponding input LED will light up.

Auto Switching

Press and hold down the Select button for at least 3 seconds to enable auto- switching mode. The operating parameters are shown below.

• The Splitter/Extender will switch to the first available active input starting with HDMI In 1
• New Input: When a new source device is detected, the Splitter/Extender will automatically switch to it
• Source Removed: When an active source is removed, the Splitter/Extender will switch to the first available active source
• Power Off: The Splitter/Extender saves the last configuration before powering off. If the last switching mode is auto switching, the splitter will automatically enter auto switching mode when it is restarted. Then if the last selected source input is still available, the Splitter/Extender will switch to it. Otherwise, it will switch to the first available active source input.

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 Splitter/Extender.
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 CAT 6/7 Receiver.

Figure 5: Source Device IR Control Connection Diagram

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 Splitter/Extender.
2. Connect an IR Emitter Cable to the IR Out port on each CAT 6/7 Receiver.
3. Point the IR Emitter Cable’s IR eye in line with the display’s IR window.

Figure 6: Display Device IR Control Connection Diagram

Controlling the Display Device(s) using IR All In Port

Allows remote controlling of all of the display devices simultaneously.

1. Connect an IR Receiver Cable to the IR All In port of the Splitter/Extender.
2. Connect an IR Emitter Cable to the IR Out port on each CAT 6/7 Receiver.
3. Point the IR Emitter Cable’s IR eye in line with the display’s IR window.

Figure 7: Display Device IR Control Connection Diagram

Note The IR All In will relay the received IR signal to all the CAT 6/7 outputs whereas the IR IN connectors associated with each CAT 6/7 output will only relay the IR signal to its respective CAT 6/7 Receiver. The IR All In can also be connected to the IR Loop Out of another Splitter/Extender when two or more units (up to a maximum of five) are connected in a cascade mode while using only a single IR detector at the start of the cascade connection.

The 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.

EDID Management

EDID is used by the source device to match the video resolution to the connected display(s). The source device obtains its EDID from the 1st connected display as default setting. However, since displays with different capabilities are often connected to the Splitter/Extender, the EDID DIP switch can be used to set the EDID to a fixed value to offer the best compatiblity accross all connected displays.

Front Panel EDID Switch

L. RES| The Extender/Splitter reads EDID from all connected displays, and then the source device will automatically use the EDID from the display with the lowest resolution
---|---
Default| The factory default EDID is 4K@60Hz, deep color, stereo audio
H. RES| The Extender/Splitter reads EDID from all connected displays, and then the source device will automatically use the EDID from the display with the highest resolution

Resolution Downscaling

The Splitter/Extender supports 4K resolution downscaling for compatibility with 1080p display devices shown in the table below.

| Input| Output
---|---|---
#| Resolution| Refresh| Color

Space

| Downscale| 1080p Specs

RS232 Control

Connect the control PC’s RS232 serial port to the Splitter/ Extender’s RS232 port using the included RS232 cable.

RS232 Control Software

Works with most serial command and monitoring software such as CommWatch

• Download CommWatch or the serial command software of your choice
• Installation: Copy the control software files and paste them to the hard drive of your PC
• Uninstallation: Delete all control software files from the PC

Basic Settings

1. Connect all input and output devices as needed, then connect the PC to the Splitter.
2. Double click the software icon to run the control software. The icon is shown below.

The examples shown on this page and the following page are from CommWatch serial command software.

Control Software Interface

Set the COM port, Baud rate, data bit, stop bit, and parity. Enter commands into the Command Sending Area.

RS232 Commands

The splitter and compatible receivers features RS232 ports to transmit RS232 signals from computer to control far-end third-party devices by using 3-pin to DB9 cable and a RS232 control software, such as docklight. After installing the RS232 control software, please set the parameters of COM number, bound rate, data bit, stop bit and the parity bit correctly. Compatible receivers must be able to communicate at 9600, 19200, 38400, 57600, or 115200 baud. The splitter requires the following communication protocol parameters: Baud rate: 9600 (default) Data bit: 8 Stop bit: 1 Parity bit: none

Note

All commands need to be ended with “”. In the commands, “[”and “]” are not needed to be typed in actual operation. Type the command carefully, it is case-sensitive.
