Notes:
・
With RS-232C communication, a few bytes of unnecessary data may be output while the HDC is being
powered off or connection is being established. Consider this possible problem when designing control
program.
・
Immediately after start-up, the communication command control function is disabled until the connection
of the sink device is confirmed. Adding “Wait” or retry processing is recommended.
