1. Introduction

1.1. About The HDMMX3232-4K (with Audio)

The KanexPro HDMMX88A-4K is an 32 input by 32 output modular matrix switcher chassis with four input slots and four output slots; each modular input or output card supports up to four device connections. As an add-on to front panel control, the HDMMX3232A-4K can be controlled via IR, RS232, or TCP/IP connections.

The optional modular input cards include the following connections: HDMI, DVI, VGA, HDBaseT (with RS232 and bi-directional wide-band IR), Fiber Optic and analog video with digital scaling via HD15 (VGA-UXGA, RGBHV, RGBS, RGsB, RsGsBs, component video, S-video and composite video). The modular output cards include the following connections: HDMI, SDI, DVI, VGA, HDBaseT and Fiber Optic. Stereo audio embedding is supported on the HDMI input cards to allow analog audio to be inserted into the digital signal. Stereo audio can also be de-embedded using the HDMI or HDBaseT output cards. Advanced EDID management restricts sources to output only stereo audio, while emulating the native video data from the attached displays. This system allows analog audio to be switched with the paired digital video, eliminating the requirement for an additional audio matrix switcher.

3.3. Application

Modular Matrix Switcher series has a good application in various occasions, such as radio & television, multi-media meeting room, big screen displaying, television education and command & control center etc.

4. Control Operations

4.1. Front Panel Button control

Users can control Modular Matrix Switcher 32x32 (with Audio) rapidly and directly with its front panel buttons. Here is a brief operation guide to front panel buttons.

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

Note:

1) "Switch Mode":

AV: Transfer AV signal from AV signal card& audio signal from audio card synchronously

Video: Transfer AV signal from AV signal card

Audio: Transfer audio signal from audio card

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

Example:

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

Functional Buttons:

UNDO button: 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.

← Button: If you press buttons "1", "AV", "2", "←" in order, then "2" will be canceled.

THROUGH button: 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.

Examples:

1、Transfer signals from an input channel to all output channels: [x]All.

Example: Send "3All." to transfer signals from the input 3 to all output channels.

2、Transfer all input signals to corresponding output channels respectively: All#.

Example: If this command is carried out, the status of matrix will be: 1->1, 2->2, 3->3, 4->4.....8->8.

3、Switch off all the output channels: All\$.

Example: After running this command, there will be no signals on all the outputs.

4、Switch off the detail feedback command from the COM port:/:MessageOff;

But, it will leave the “switch OK” as the feedback, when you switch the matrix.

5、Switch on the detail feedback command from the COM port:/:MessageOn;

It will show the detail switch information when it switch. Example: when switch 1->2, it will feedback "AV01 to 02".

6、Transfer signals from an input channel to corresponding output channel: [x]#.

Example: "5#." to transfer signals from the input 5 to the output 5.

7、Switch off an output channel: [x]\$

Example: “5\$.” to switch off the output 5.

8、Switch signal: [x1] B[x2].

Example: "1B2,3,5." to transfer signal from the input 1 to the output No. 2,3,5.

9、Inquire the input channel to the output channel [x]: Status[x].

Example: Send "Status2." to inquire the input channel to the output 2.

10、Inquire the input channel to the output channels one by one: Status.

Example: "Status." to inquire the input channel to the output channels one by one.

11、Save the present operation to the preset command [Y]: Save[Y].

Example: "Save7." to save the present operation to the preset command No.7.

12、Recall the preset command [Y]: Recall[Y].

Example: "Recall5." to recall the preset command No.5.

13、Clear the preset command [Y]: Clear[Y].

Example: "Clear5." to clear the preset command No.5.

14、EDID management command:. EDIDM[X]B[Y].

Example: "EDIDM5B3." to enable input 3 to learn the EDID data of output 5.

15、Command for signal cards: USER/[Y]/[X]*****.

Example: "USER/I/7:0623%;" to set the input 7 to support YPbPr signal, the card is plugged in the second input slot of the matrix.

Note: If there is any empty input card or output card, and send the command "ALL#." It will be taken and the result is as 1->1, 2->2, 3->3..., but actually there is no input/output signal at this card.

4.3. TCP/IP Control (Optional)

4.3.1. Control Modes

TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and Serial Port is 4001. IP & Gateway can be changed as you need, Serial Port cannot be changed.

- Controlled by Single PC

Connect a computer to the TCP/IP port of the Modular Matrix Switcher 32x32 (with Audio), and set its network segment to the same as the default IP of the Modular Matrix Switcher 32x32 (with Audio) (192.168.0.178).

- Controlled by PC(s) in LAN

The Modular Matrix Switcher 32x32 (with Audio) can be connected with a router to make up a LAN with the PC(s), this make it able to be controlled in a LAN. When control, just make sure the Modular Matrix Switcher 32x32 (with Audio)'s network segment is the same with the router. Please connect as the following figure for LAN control.

graph TD
    A["TCP/IP"] -->|TCP/IP| B["Router"]
    B --> C["PC"]
    B -->|CAT5e| C
    B -->|Internet| D["Internet"]

Step1. Connect the TCP/IP port of the Modular Matrix Switcher 32x32 (with Audio) to Ethernet port of PC with twisted pair.

Step2. Set the PC's network segment to the same as the Modular Matrix Switcher 32x32 (with Audio). Do please remember the PC's original network segment.

Step3. Set the Modular Matrix Switcher 32x32 (with Audio)'s network segment to the same as the router.

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

Step5. Connect the Modular Matrix Switcher 32x32 (with Audio) and PC(s) to the router. In the same LAN, each PC is able to control the Modular Matrix Switcher 32x32 (with Audio) asynchronously.

Then it's able to control the device via a TCP/IP communication software.

4.3.2. Control Modular Matrix Switcher 32x32 (with Audio) via TCP/IP communication software

(Exampled by TCPUDP software)

1) Connect a computer and Modular Matrix Switcher 32x32 (with Audio) 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 Modular Matrix Switcher 32x32 (with Audio) (default IP: 192.168.0.178, port:4001):

2) After connect successfully, we can enter commands to control the Modular Matrix Switcher 32x32 (with Audio), as below:
