1. System Frame and Protocols
TCP/IP and RS485 are the mainly Protocols which being used ion Smart-BUS Intelligent Control System.
For example：We use RS485 protocol for the communication between each device, then we use TCP/IP protocol for the communication of Ethernet interface device.
System can be integrated with other protocols such as RS232、DMX512、DALI、OPC、EIB ETC.

2. Description of System Protocol——
TCP/IP：
The standard International communication Language & Protocol, it is short for “Transfer Control Protocol/Internet Protocol”.
RS485：
RS 485 is the same as the RS232, RS422, they are mostly used in Data Communication , Computer Network, and also the Distributed Industry Control system, for the data converter and transmission.
DMX512：
DMX is short for Digital Multiplex，512 means there are maximum 512 bytes of Control Signal in the DMX512 cables at one time. The Protocol was made by Technology Association of American drama in It was mainly used for the communication between console and Dimmer but now the DMX512 Protocol is expanded to other device, such as color changer, computer lights, Smoker Generator and so on.

3. Description of System Protocol——
DALI：
DALI is short for ----Digital Addressable Lighting Interface.
It defines the communication Protocol Between Ballast and Device controller. Those Ballast who under protocol of DALI use Lower Voltage cable as the Lighting control BUS.
All ballast in the BUS can get a address automatically, so the Fluorescent light can be separate control or Random Group Control
EIB：
European Installing Bus, it is Dominance standard used in Europe.
OPC：
OPC is short for ---OLE for Process Control.
It is a industry process control standard. Before the birth of OPC , there is no Unified standard between the Hardware Driver and connected application software interface. OPC is used for the target of solving the problem of different device and software from different Factory. To make it unified then it will be more easy for data transfer and integration.
