Introduction
This document describes the hardware interface spec and software protocols of RS232 interface
communication between Commercial Display and PC or other control unit with RS232 protocol.
This set protocol allow users to assign the ID in the command to control the specify ID monitor.
The set protocol contains two sections command: Set-Function and Get-Function
In this document, "PC" represents all the control units that can send or receive the RS232 protocol command.

Command message reference
PC sends to Monitor command packet followed by "CR". Every time PC sends control command to the
Monitor, the Monitor shall response as follows:
1. If the message is received correctly, it will send "+" (02Bh) followed by "CR" (00Dh).
2. If the message is received incorrectly, it will send "-" (02Dh) followed by "CR" (00Dh).
Connections and communication settings
Choose one of the connections and set up properly before RS232 control.
