Communication protocol
Communication is carried out in units of 1 byte. After the computer transmits one byte of data, it waits for a
response from the multiplexer, and then transmits the next byte of data.
To start sending commands, an ON (F6) command is sent. The multiplexer will continue to receive
commands until an OFF (F7) command is sent to stop. The multiplexer sends an ACK (OA) each time it
receives a command.
See Table 4 - Command Table on page 79.
