Data Bits
This parameter allows the reader to interface with devices requiring a 7-bit or 8-bit ASCII
protocol for sending and receiving data.
Stop Bits
The stop bit(s) at the end of each transmitted character marks the end of transmission of one
character and prepares the receiving device for the next character in the serial data stream. The
number of stop bits selected (one or two) depends on the number the receiving terminal is
programmed to accommodate. Set the number of stop bits to match host device requirements.
NOTE
The scanner cannot support 7-bit-data when parity-none is set.
