Communication protocol
Communication is carried out in units of 1 byte. After the
PC has transmitted a single byte, it waits for a response
from the unit before sending the next byte.
An ON (F6) command is sent as the start command, and
the unit will continue to accept commands until an OFF
(F7) command is sent as the end command. Whenever the
unit receives a command, it returns an ACK (OA).

recommended.
