General Command Structure
Example: 0x06 0x11 0x00 0x01 0x02 checksum
Length of the command
Function Sum of the total bytes of the command
The first byte of command is length of commands.
Define byte:0x0 0x1 x0x2 0x3 0x4 0x5 0x6 0x7
Checksum is total sum of command number.
Checksum=0x06+0x11+0x00+0x01+0x02=0x1A
3. UNDERSTANDING THE RS-232 COMMANDS
Before you start issuing the commands, let’s walk you through the structure of the commands.
Understanding the structure of the commands will allow the user to create further commands that are stated in this document. To
create their own special commands for each situation or project.
Rev. 00 11/2017
NOTE: Please note the checksum value has to be calculated correctly in order for the command to be executed. Simple tool
can be used such as the Windows Calculator in Programmer mode or Hex table as shown below.
