Operating Parameters
Device Type
Baud Rate, Parity and Data Bit:
These parameters set the scanner's communication protocol that must be
matched by the host. The default setting for the serial interface is 9600 baud rate,
none parity, and 8 data bit.
Baud Rate can be 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400
bps.
Parity can be even, odd, space, mark, or none.
Data Bit can be 7 or 8 long.
The scanner may not support settings with Data Bit as 7 and Parity as none
combination. Such combination is treated as 7 data bits with MARK parity.
Handshaking:
The scanner supports CTS/RTS handshaking as an option. The hardware
handshaking is supported on character-by-character basis.
During the communication, the scanner will stop sending data until the CTS is
valid within time specified by the Time Out parameter. During this time-out
waiting period:
If CTS is valid.
If CTS is not valid, the scanner sounds an error beep and discards the
current buffered data.
BCC Character:
BCC check character is calculated for entire data stream by using "Exclusive
OR" method. it is sent after data stream for data verification.
Time Out:
You can adjust the Time Out duration for handshaking and ACK/NAK protocol
to fit applications.
