Using the Matrix

Power LED and Standby Mode
The Power LED provides the following indications:

Off

| The Matrix is in standby mode, this state can be changed by using API commands or IR Remote, or from the Web GUI interface.

Selecting Inputs
Manual Selection of the inputs is done by briefly pressing the OUT 1 / OUT 2 / OUT 3 / OUT 4 button repeatedly for that channel until the desired input is selected.

 IR Remote

| Power on the Matrix or set it to standby mode.
---|---
Output 1 (Output 2 / 3 / 4)
1/2/3/4| Select the desired input source to Output 1 port output, the corresponding green LED on the front panel illuminates.
SD| Switch downscale or bypass mode to the Output 1 port output.
| Select the last or next the desired input source to Output 1 port output, the corresponding green LED on the front panel illuminates.

Battery not include (CR2025)

• How to use Switch Downscale [SD] or bypass mode
• Press SD button when a 1080 monitor is receiving a 4k input source
• Example:
• Input 1 is 4K content
• Output 1 is a 1080p monitor
• Output 2 is a 4K monitor
• If you want to display Input 1 to Output 1. The monitor will not detect a signal because the content is 4K. Once the SD button is pressed the matrix downscales to 1080 to be able to display on this  output. Since Output 2 is 4K it should automatically receive the 4k content. Both Monitors will display simultaneously.

Using the Built-In Web GUI Interface

The Matrix has a built-in Web interface to provide a means of controlling and configuring various settings. There are six pages available, each of which will be outlined in detail in the following sections:

The six pages are:

1. Status – Display information about the firmware and IP setting.
2. Video – Switch the desired input source to output and set the preset.
3. Input – Display information about the input signal and EDID setting.
4. Output – Display information about the output signal and scaler option.
5. Network – Allow basic network setting management and login options.
6. System – Panel lock, beep, serial baud rate setting and firmware update.

Note these six pages are only accessible in Admin mode, when User mode is used only the Status and Video pages are available.
To access the Web interface, enter the IP address of the matrix into the address bar of any web browser. The matrix is defaulted to DHCP but in the event no router has assigned an IP, the default IP address will be 192.168.1.100.
Note that if the IP address of the matrix is not known there are 2 methods to identify the IP:

1. Use the RS-232 command given in the Network Setting section “r ip addr!” to discover the current IP address or set the matrix to factory default status and IP address restores to default 192.168.1.100.
2. Use a 3rd party computer application like Advanced IP scanner or Angry IP Scanner to identify the matrix on your network. The Matrix is usually named “IP Module” but may appear under a different name.
   • Step 1: The TCP/IP port on the rear panel is directly connected a PC with an ethernet cable.
   • Step 2: Set your PC IP address to the same network segment with Matrix, for instance set PC IP address to 192.168.1.200 and Subnet mask to 255.255.255.0.

Step 3: Enter the Matrix’s IP address into your browser on the PC to enter Web GUI page.

After entering the IP address the following log in screen will appear:

Select the Username from the list and enter the password. The default passwords are:

• Username User Admin
  Password user admin

After entering the log in details, click the LOGIN button and the following Status page will appear.

Status page
The Status page provides basic information about the product Model name, the installed firmware version and the network setting. This page is visible in both User and Admin modes.

• The buttons at the top right of the web interface are always available and provide the following function:

  • The Log out button will disconnect the current user from display the log in screen.
  • The Power on button changes the power status of the Matrix between On and Stand-by mode.

• Video page

  • The Video page allows selection of the inputs and presets.
  • There are four assignable presets available.
  • To preset a setting, first you need to select the desired input source to the output port(s). Then click the Save button to save the setting. When you click the Set button, this preset you have saved will be used. The Clear button will clear the preset.

• Input page

  • The Input page provides information about which inputs are connected and have a signal present. The inputs names can be edited. The EDID column provides a list of EDID options for each input.

  • The following EDID options are available in any of the EDID drop-down lists:

  • 1080P, Stereo Audio 2.0 1080P, Dolby/DTS 5.1

  • 1080P, HD Audio 7.1

This page also provides a means of sending a binary EDID file to either User 1 or User 2 EDID memories:

1. Select the binary EDID file on your PC by click on the Browse button.
2. Select either User 1 or User 2 from the drop-down list.
3.  Click the Upload button.

The EDID data from any input or from the User 1 and User 2 locations can be read and stored on your PC.

Output page
The output names can be edited. The Output page provides information about the signal status of the outputs.

The Scaler mode menu provides the following options:

• The ARC buttons enable or disable the display device audio to the coaxial audio outputs. If the ARC function is enabled, the L/R audio port will be disabled.
• The Stream buttons enable or disable the output signal for the respective output.

Network page

• The Network page allows the configuration of the network settings. Note that the IP address boxes are only accessible when the Mode button is set to Static.
• The log in passwords can be changed on this page.
• Note that any changes to this page will require the new details typed into the web browser and/or the log in screen.

System page

• The system page allows setting the panel lock, beep on/off, and RS-232 port baud rate.
• This page is also used to install new firmware update, restore the factory default settings and reboot the Matrix.

 API control command

The Matrix can also be controlled by RS-232. Connect a PC by using a serial cable and open any of a Serial Command tool on the PC such as Comm Operator, Docklight or Hercules to send commands for controlling the Matrix. Please see the following connection diagram.

• Baudrate: 115200(default)
• Data bits: 8
• Parity: None
• Stop bits: 1

https://avi.co/acr-b1u-c20

Important:

1. All messages sent to the Matrix must be terminated with an exclam- ation mark (!). Any carriage return that is present after the end of the command will be ignored.
2. All spaces shown in the commands are required.
3. All response messages are terminated by a CR/LF sequence.
4. When all four inputs are requested by the same command, the response will report each input on a separate line.
5. When four outputs are requested by the same command, the response will report each output on a separate line.

The ASCII list about the product is shown as below.
