3-4-1 Connection Method
Connect the bar code reader to serial port A of the NT31/NT31C, as shown in
the figure below.
Bar code reader must match the communications setting (3-4-2 Setting a Bar
Code Reader, page 35) and data format (3-4-3 Data Format, page 36) in
order to connect to the NT31/NT31C. Please confirm the specification of the
bar code reader before using.

bar code reader is used, the host must be connected at serial port B.
