Note: All the input and output signal cards do not support hot-swop, but the physical input and output ports on the signal cards support hot-plug.

4. Button Control

The Matrix can be controlled via the front panel buttons. Here is a brief operation guide.

Format: "Input Channel" + "Switch Mode" + "Output Channel"

Note:

- "Switch Mode":

√ AV: Switch AV signal from AV signal card and audio signal from audio card synchronously.
√ Video: Switch AV signal from AV signal card.
√ Audio: Switch audio signal from audio card.

• "Input Channel": Fill with the number of input channel to be controlled.
• "Output Channel": Fill with the number of output channels to be controlled. Press "All" to select all the outputs.
• The input / output channels on the rear panel are counting from left to right, top to bottom.
• The input delay time between two numbers of every input and output channel must be less than 5 seconds; otherwise, the operation will be cancelled.

Example:

• To switch input 1 to output 1, press input "1", output "1".
• To switch signals from input 1 to all output channels, press buttons in this order: "1", "All".

Functional Buttons:

• UNDO: Return to the previous status

Example: Input 6 is connecting with output 6, press input "6" + "AV"+ output 4 to change the connection. Press "Undo" to enable input 6 to reconnect with output 6.

• ←: When pressing buttons "1", "AV", "2", "←" in order, then "2" will be canceled.
• THROUGH: Get straight I/O connection, e.g., input 1 → output 1, input 2 → output 2.

Press "Input Channel" + "Through"

Example: If you press buttons "ALL", "THROUGH" in order, then the result will be like input 1 → output 1, input 2 → output 2, input 3 → output 3 ... input 8 → output 8.

5. IR Remote Control

The matrix can be controlled via the remote controller. As the function buttons on the IR remote are the same as the ones on the front panel, the IR remote shares the same operations and commands with the control panel.

Press the buttons under below format:

"Input Channel" + "Switch Mode" + "Output Channel"

INPUTS 1 2 3 4 5 6 7 8 9 0 10+ AV VIDEO AUDIO ALL THROUGH UNDO ← 1 2 3 4 5 6 7 8 9 0 10+ OUTPUTS Professional Audio/Video Matrix Switcher

INPUTS 1 2 3 4 5 6 7 8 9 0 10+

Input channel buttons, including 1\~10+, only 1\~8 is available.

AV VIDEO AUDIO ALL THROUGH UNDO

Menu buttons, including switching buttons and function buttons.

1 2 3 4 5 6 7 8 9 0 10+ OUTPUTS

Output channel buttons, including 1\~10+, only 1\~8 is available

6. RS232 Control

6.1. RS232 Communication Port

Apart from the front control panel and IR remote control, the Matrix can also be controlled by a far-end control system via the RS-232 communication port.

This RS-232 communication port is a female 9 pin D-SUB connector. The definition of the pin layout is shown in the below table.

5 1 9 6 Female

No.	Pin	Function
1	N/u	Unused
2	Tx	Transmit
3	Rx	Receive
4	N/u	Unused
5	Gnd	Ground
6	N/u	Unused
7	N/u	Unused
8	N/u	Unused
9	N/u	Unused

6.2. RS232 Control Software

When the Matrix connects to the RS232 port of a computer with control software, users can control it via that computer. To control the switcher, users need to use RS232 control software.

• Installation: Copy the control software file to the computer connected with the Transmitter.
• Uninstallation: Delete all the control software files in corresponding file path.

- Basic Setting

Connect the Matrix to all input devices and output devices needed, then connect it to a PC which has RS232 control software installed. Double-click on the software icon to run the software. Here we use the software CommWatch.exe as example. The icon is shown below:

CommWatch.exe

The interface of the control software is showed below:

Parameter configuration area UART(SerialPort) Test Tool (V1.0) PORT Com1 BaudRa 9600 Parity pNone Byte 8 Stop 1 Reset Clear Save To File Hex View Stop View Auto Clear View New Line Hex Send Mode Send Auto Send Load File Interval 1000 ms Counter Reset Clear 2013-05-08 14:03:35 Send:0 Receive:0 V1.0 Monitoring area, show the commands and its feedback information. Command sending area

Please set the parameters of COM number, baud rate, data bit, stop bit and the parity bit correctly, then only can the RS232 commands be sent in Command Sending Area.

6.3. RS232 Communication Command

With this command system, users are able to control and operate the Matrix with RS232 software remotely.

Note:

• Please disconnect all the twisted pairs before sending command EDIDUpgrade[X].
• In the commands, “[”and “]” are symbols for easy reading and do not need to be typed in for actual operation.
• Please remember to end the commands with the ending symbols “.” or “.”
• Type the command carefully, it is case-sensitive.
• Commands pertaining to EDID only avails for signal cards that support EDID management.
• The matrix boasts 6 built-in EDID data, the chart below illustrates the detailed information:

No.	Detailed Information
1	1080P 2D 5.1CH
2	1080P 2D 2.0CH

7. TCP/IP Control

7.1. Control Mode

TCP/IP default settings:

IP: 192.168.0.178,

Gateway is 192.168.0.1,

Serial Port: 4001.

IP and Gateway can be changed as required; the Serial Port cannot be changed.

• Control via Single PC

Connect a computer to the TCP/IP port of the ALF-MMX88A-N and set its network segment to the same as the default IP of the ALF-MMX88A-N (192.168.0.178).

Internet Protocol Version 4 (TCP/IPv4) Properties General You can get IP settings assigned automatically if your network supports this capability. Otherwise, you need to ask your network administrator for the appropriate IP settings. Obtain an IP address automatically Use the following IP address: IP address: 192 . 168 . 0 . 227 Subnet mask: 255 . 255 . 255 . 0 Default gateway: 192 . 168 . 0 . 1 Obtain DNS server address automatically Use the following DNS server addresses: Preferred DNS server: 202 . 96 . 134 . 133 Alternate DNS server: 202 . 96 . 128 . 68 Validate settings upon exit Advanced... OK Cancel Same network segment as the switcher

• Control via PC(s) in LAN

The ALF-MMX88A-N can be connected with a router to make up a LAN with the PC(s), this enables it to be controlled in a LAN. Ensure the ALF-MMX88A-N network segment is the same as the router. Please connect as the following figure for LAN control.

graph TD
    A["TCP/IP"] -->|TCP/IP| B["Router"]
    B --> C["PC"]
    B -->|CAT6| C
    C --> B
    B -->|Internet| D["Data Packet"]

Step1. Connect the TCP/IP port of the ALF-MMX88A-N to Ethernet port of the PC with twisted pair.

Step2. Set the PC's network segment to the same as the ALF-MMX88A-N. Do please remember the PC's original network segment.

Step3. Set the ALF-MMX88A-N's network segment to the same as the router.

Step4. Set the PC's network segment to the original one.

Step5. Connect the ALF-MMX88A-N and PC(s) to the router. In the same LAN, each PC is able to control the ALF-MMX88A-N asynchronously.

It is now able to control the device via TCP/IP communication software.

7.2. TCP/IP Communication Software

(Exampled by TCPUDP software)

1) Connect a computer and ALF-MMX88A-N to the same network. Open the TCPUDP software (or any other TCP/IP communication software) and create a connection, enter the IP address and port of ALF-MMX88A-N (default IP: 192.168.0.178, port:4001):

Create Connection Type: ICP DusLIP: 102.168.0.178 Port: 4001 LocalPort Auto Specia 4001 AutoConn: Eve x Send View Conn: Eve ns Create Cancel

2) After successfully connecting, we can enter commands to control the ALF-MMX88A-N, as below:

192.168.0.178:4001 DestIP: 192.168.0.178 DestPort: 4001 LocalPort 4001 Type TCP AtuoConn Eve 0 AutoSend Evo 0 ns Connect Count Send 0 Recv 0 Clear Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0 Send Snoop(R/S): 0
