MATRIX SYSTEM OVERVIEW

Matrix System

The Matrix Switch is a high performance system used to switch

audio/video frequencies. It will cross switch multiple input/output

audio/video signals through independent Y/Pb/Pr component and

audio input/output terminals. Each Y/Pb/Pr component signal and

audio signal is transmitted separately and switched separately,

thereby minimizing signal attenuation and ensuring high definition

graphics and high fidelity audio signal output.

The primary use is; TV broadcasting projects, multi-media conference

halls, large display projects, TV teaching, and command control

centers. It features power interruption protection during power surge,

LCD display, and synchronous and separate audio/video switching

functions. The RS-232 and RS-485 communication ports enable

convenient communication with remote control equipment. This

manual describes the SW404HD and SW808HD models.

Address Byte (Command Type A and B)

CRC

Broadcast Reserved

CRC

BT: Broadcast

0: Instruction for one machine with matching Machine ID

1: Instruction for all machines

If BT = 1, machine will not return a response packet.

If BT = 0, machine must respond

CRC: CRC-8

0: Host (computer) does not append a CRC byte at end of

command packet

1: Host appends a CRC byte to end of command packet

Instruction Code Byte (Command Type A and B)

VAR

Variable

Reserved Instruction Code (6-bit command)

Length

VAR: Variable Length

0: The command packet is 4 bytes with Output and

Input bytes

1: The command packet is variable length and

contains a length byte indicating the number of

Output and Input bytes

Length Byte (Command Type B only)

Number of Output and Input Bytes to follow not including CRC

Output Byte (Command Type A and B)

Refer to Command Table

Input Byte (Command Type A and B)

Refer to Command Table

CRC (Command Type A and B)

CRC-8 calculated from all bytes in packet.

Appended if CRC bit set in Instruction code
