CHAPTER 1 OVERVIEW

1.1 Introduction

The HX-2544/2562 Matrix switcher is a high performance HDMI switching equipment

combining with video and audio. It is used for input/output cross switching of image

signals. It can also transmit images input separately to each multi-output equipments,

thereby minimizing signal attenuation and ensuring high definition, integrating high

fidelity graphics and audio signal output.

The HX-2544/2562 is used mainly in TV broadcasting projects, multi-media conference

halls, and large display projects, TV teaching and command control centers. It boasts

features of power interruption protection during power surge, LCD display and

synchronous and integrate audio/visual switching functions. HX-2544/2562 supports 4 to

4/6 to 2 HDMI Type A for input and output connectors. Beside it also supports RS-232

and LAN communication ports enable convenient communication with remote control

equipment to switch the image signals.

CHAPTER 9 TROUBLESHOOTING

1. What to do if LCD is fail in display?

Answer: Check the connection of power cord is not loosening and the power cord is in a

good status having no any damage. Check the power source is normally.

2. What to do if the HDMI Matrix front panel keys switching not responsive?

Answer: The HDMI Matrix front panel keys employ scanning testing and require longer

response time. Press the keys for 2 seconds and then release. This way, key

switching will be responsive in operation.

3. What to do if the serial port (usually refer to the computer serial port) fails to control the

HDMI Matrix?

Answer: Check that the communication port set by the control software is correctly

connected to the corresponding serial port of the equipment. Also, check if the

computer communication port is in good order. Check the ID address and DIP

Switcher are configured correctly.

4. What to do if the corresponding audio signal fails to output during HDMI Matrix

switching?

Answer:

(1) Check if there is signal on the input end. If there is no input signal, it could be that the

input connection cable is broken or the connector gets loosen. You are advised to

replace the connection cable.

(2) Check if there is signal on the output end. If there is no output signal, it could be that

the cable is broken or the connector gets loosen. You are advised to replace the

connection cable.

(3) Check if the output port number is the same as the controlled port number.

(4) Check the connections of input and output ports are correctly.

(5) If none of the above circumstances happen, it could be internal failure of the product

itself. You must send for repair by qualified technical engineers.

5. What to do if you sense the power leakage during plugging or unplugging of the

input/output ports?

Answer: It could be that the equipment power is not properly grounded. You must

properly ground your equipment; otherwise product life can easily be shortened.

6. What to do if the HDMI Matrix panel keys and communication ports are out of order?

Answer: Check if the equipment power input is in good contact and the computer

communication ports are in good order. If yes, it could be some internal failure of the

product, please send for repair by qualified technical engineer.

7. What to do if operation and function failure occurred?

Answer: Check if the equipment and the Matrix system are in proper connection. If the

problem persists, send the product to the maintenance center for repair.

8. How to avoid the equipment failure due to the high temperature?

Answer: Place the equipment in a ventilate location. If it is still not to be improved,

please check with the build-in fan whether is damaged. Or contact your agency for

helping.

9. What to do if IR function failure occurred?

Answer: Check the remote controller is in a fully battery and the IR connector is not

loosening. Check whether the remote controller is aiming at the IR receiver accurately.

APPENDIX B FIRMWARE UPGRADE

This Chapter will brief introduce you how to upgrade firmware on your web browser. For

firmware upgrade, you have to upload the firmware file to your web server and then

upload it to your device from web server. In order to avoid the error during upgrading, we

suggest that it is better to contact your local agency for helping.

Open the Browser on your PC, key in the default IP address: http://192.168.0.3 to login

the AV MA TRIX Control configuration. Click “F/W Upgrade” to begin firmware upgrade.

APPENDIX C RS-232 COMMUNICATION PROTOCOL

This AV Matrix RS-232 communication protocol uses fixed length with 5 bytes of

information as define below. The default baud rate is 9600 bps, no parity, 8 data bit and

1 stop bit. Command timeout is 300 milliseconds, and byte to byte timeout is 30 ms.

Use the RS-232 connecting cable to connect the computer serial port to the RS-232

communication port of the Matrix Switcher. The computer can control the Matrix Switcher

via RS-232. Aside from using the front panel keys for operation, you are also permitted

to use the RS-232 connection port for remote operation.

CB CRC (cyclic redundancy check)

CRC: Host must send CRC code to follow the last byte.

Example: 20 01 05 03 93 --- Device ID 0, Switch Video Output 6 to the Input 3.

Byte 1 (DB) is 0x20 – Device: Identifier + Device ID = 0x20 + 0 = 0x20

Byte 2 (RB) is 0x01 – Request: Switch Video Output Channel = 0x01

Byte 3 (IB) is 0x06 – Index: Output 6 = 6

Byte 4 (VB) is 0x03 – Value: Input 3 = 3

Byte 5 (CB) is 0x93 – CRC code from Byte 1 to Byte 4. (CRC4). CRC is 0x93

CRC Calculation

CRC 0 = 0 (initial value)

CRC 1 = Crc8(CRC 0 ^ Byte 1) = Crc8(0x20) = 0x23

CRC 2 = Crc8(CRC 1 ^ Byte 2) = Crc8(0x23 ^ 0x01) = Crc8(0x22) = 0x9F

CRC 3 = Crc8(CRC 2 ^ Byte 3) = Crc8(0x9F ^ 0x06) = Crc8(0x99) = 0x8D

CRC 4 = Crc8(CRC 3 ^ Byte 4) = Crc8(0x8D ^ 0x03) = Crc8(0x8E) = 0x93

ACK Byte + CRC Byte (Total 2 Bytes)

Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

AB ACC 0 0 Device ID (0 – 31)

CB CRC

ACC: The devices acknowledge status. Accept or Reject.

1: device accepts this request. (ACK; acknowledge)

0: device rejects this request. (NAK; negative acknowledge)



The device sends the Nak packet is always 2 bytes. (NAK + CRC)

0: Reserve, Always 0.

1: Identifier, Always 1.

Device ID: Device id ranges from 0 to 31. (Please refer to device’s user manual)

CRC: Device always sends the CRC code to follow the last byte.

AB & CB: These are the same as the ACK Type A.

LB: LB value is equal to the total data bytes (Index + Value), not include the CRC byte.

The maximum LB value of the ACK Type B is twice the total number of output or

input.

IB: Often means that the input or output port number. (Port 1 = 1, Port 2 = 2… Port n = n)

VB: Response the status refers to the table.
