3-1. RS-232 Protocol Command
The RS-232 Commands use only ASCII characters which can be entered using a typical
terminal emulator like Windows HyperTerminal with the following setting:
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Note that each input character will be echoed on the terminal by MCU and there is no
need to set the local echo “ON” with the terminal setting.

commands is as follows:
op
[SP]
<operation command>
[SP]
<Setting Value>[CR]

CAPS. Please refer to the following table for command list and examples:
