Œ After setting the commands mentioned above, it’s necessary to add the termination
code “CR(0DH) and LF(0AH)”.
• If the command is not correct, it will reply “E” + “Command Unidentified”. Ž If setting command mode with address (RS1-06 = 4), add “@ address” in front of each
command.
Example: When RS1-08 = 1, for reading weight value, the whole complete command
should be “@01RW(CR)(LF)”.
