SICP (Serial Interface Communication Protocol)
This document defines all the command and messages exchanged between the
Master (a PC or the other controller) and the Slave (the displays).
It also describes the ways to send or read the commands or the messages.
1. Protocol definition
SICP stands for "Serial Interface Communication Protocol".
The protocol is specifically designed to allow data communication in half duplex multi-point environments,
but it can also be used for half duplex point-to-point RS‑232C communication.
2. Communication characteristics
A half duplex communication is implemented starting from the concept of a master-slave structure, where
the display is supposed to be the slave.
The first action is always taken by the master, which can be either a PC or any controlling device (acting
as server) interfaced to the monitor. After sending a command or a request in the appropriate format the
master receives from the slave an acknowledgement, which tells the transmitter whether the command is
not valid (or not executable, anyway) or it is accepted. In case of a request, the requested information is
sent back and it becomes the acknowledgement by itself.

4. Hardware Protocol
Baud rate : 9600 bps
Data bits : 8 bit
Parity bits : None
Stop bits : 1 bit
Handshake : None
5. Transmission Formats
This is the format that the computer will send to the display to execute commands .
The format for this command transmission is as follows:
( total 13 byte )
ex) <STX>001PWRWOFF0<ETX> ( Set ID : 1 , Power Off Send )
STX ID1 ID2
0x0f 0 0
Hex
- STX : Start of Text ( 0x0f )
- ID1 ~ ID3 : Set ID ( 001~100 )
- CM1 ~ CM3 : Command ( PWR, MIN, MUT,RML,KPL...... )
- R/W : Read/Write
- DA1 ~ DA3 : Data ( Values )
- IND : Index
- ETX : End of Text ( 0x0d )
