CHAPTER 3: SYSTEM CONNECTION
3.3 CONNECTION PROCEDURE
STEP 1: Insert the necessary signal cards into the card slots.
STEP 2: Connect the source device(s) (e.g. Blu-ray™ DVD) to the corresponding input ports.
STEP 3: Connect the displays to the corresponding output ports.
STEP 4: Connect the amplifier/speaker to the audio output ports.
STEP 5: Connect an IR Receiver to IR EYE to enable IR control.
STEP 6: Connect a control device (e.g. a PC) to the RS-232 port to enable serial control..
STEP 7: Connect a control device (e.g. a PC) to the TCP/IP port to enable TCP/IP control.
STEP 8: Plug the included power cord into the 100–240 VAC outlet.
NOTES:
1. When connecting to HDMI 2.0 sources, make sure the HDMI cable is compliant with HDMI 2.0 to ensure reliable transmission;
2. Connect amplifiers that can decode HDMI audio to the SPDIF ports, or there will be no output on the amplifiers.
3.4 SYSTEM APPLICATIONS
Because of its flexible card design, the Matrix Switcher is an all-in-one solution that is ideal for different applications, such as
public displays, educational demos, professional presentations, advertising displays or control centers. The switcher can handle all
the audio-visual management, including the switching, driving, scaling, etc.

CHAPTER 4: FRONT-PANEL CONTROL
The Matrix Switcher provides convenient front panel button control for I/O switching, EDID management, and system inquiry.
4.1 SWITCHING I/O CONNECTION
Input/output channels are recognized in double-digit, press 01–09 for channel 1–9.
1. To convert one input to an output:
Operation: “INPUT”+“OUTPUT”+“ENTER”
Example: transfer input 1 to output 5:
INPUT: 0 1 —> OUTPUT 0 5 —> ENTER
2. To convert an input to several outputs:
Operation: “INPUT” + “OUTPUT” + “OUTPUT” +… + “ENTER”
Example: Switch input 2 to output 4, 5
INPUT: 0 2 —> OUTPUT —> 0 4 0 5 —> ENTER
3. To convert an input to all outputs:
Operation: “input” + “ALL” + “ENTER”
Example: Convert input 2 to all outputs
INPUT: 0 2 —> ALL —> ENTER
4.2 EDID LEARNING
The Matrix Switcher features EDID management to maintain compatibility between all devices.
One input port learns the EDID data of one output port:
Operation: “EDID”+“INPUT”+“OUTPUT”+“ENTER”.
Example: Input 1 learns EDID data from output 10.
EDID —> INPUT: 0 1 —> OUTPUT: 1 0 —> ENTER
All input ports learn EDID data from one output port:
Operation: “EDID”+“ALL”+“OUTPUT”+“ENTER”
Example: All input ports learn EDID data from output 6
EDID —> ALL —> OUTPUT: 0 6 —> ENTER

4.4 CLEAR OPERATION
Function: Clear the previous operation before pressing ENTER to enforce it. Pressing CLEAR can only erase the operations not confirmed
by pressing ENTER.
Input/output channels are recognized as double-digits; press 01–09 instead of 1–9.
The input delay time between two numbers of every input and output channel must be less than 8 seconds; otherwise, the
operation will be cancelled.
The input/output channels on the rear panel are counting from left to right, whether or not there is signal card.

CHAPTER 5: RS-232 CONTROL
The Matrix Switcher has one RS-232 port for serial port control. Connect the Matrix Switcher to the control device (e.g. a PC) with
RS-232 cable and set the correct parameters. The control device can control the Matrix Switcher via designed software.
5.1 RS-232 CONTROL SOFTWARE
Installation: Copy the control software file to the computer connected with the Matrix Switcher.
Uninstallation: Delete all the control software files in corresponding file path.
5.2 BASIC SETTINGS
Connect the switcher to the necessary input devices and output devices. Then, connect it with a PC installed RS-232 control
software. Double-click the software icon to run this software.
Here we show an example using the software CommWatch.exe. The icon is shown next.
FIGURE 5-1. COMMWATCH ICON
The interface of the control software is shown next.
FIGURE 5-2. CONTROL INTERFACE
Set the parameters (baud rate = 9600, data bit = 8, stop bit = 1 and parity bit = none) correctly to ensure reliable RS-232 control.
