(Note 1) The Input / Output direction is stipulated from the BHT side.
(Note 2) Use the exclusive cable only.
(Note 3) When the RS-232C detect signal is at a low level, it will detect that the BHT is
connected to the RS-232C interface.
(On the RS-232C cable side there will be a short from pin 1to pin 9)
