TRANSMISSION PROTOCOL
The transmission is based on 1 byte units. After the computer has transmitted 1 byte, it will wait for an answer from this unit, then send the following byte of data.
The command ON (F6) is sent to start, and the command OFF (F7) is sent to finish. This unit will receive the commands, and will reply to each command by ACK (OA). (Refer to “COMMAND TABLE 4 ” on page 31.)
