Character Length
The character length specifi es the number of bits that will defi ne
a character. Eight bits are recommended, because that option
allows more special characters and characters specifi c for foreign
laguages to be used. Refer to the
Intermec Fingerprint v7.61,
Programmer’s Reference Manual for information on which charac-
ters are available in various combinations of character length and
character set.
• 7 Characters ASCII 000 to 127 decimal
• 8 Characters ASCII 000 to 255 decimal (default)
Parity
The parity decides how the fi rmware will check for transmission
errors. There are fi ve options:
• None (default)
• Even
• Odd
• Mark
• Space
Stop Bits
The number of stop bits specifi es how many bits will defi ne the
end of a character. There are two options:
• 1 (default)
• 2
Flow Control
• RTS/CTS
RTS/CTS is a protocol where the communication is con-
trolled by currents through separate lines in the cable being set
either to high or low. By default, this option is disabled.
RTS high indicates that the transmitting unit is able to receive
characters. RTS low indicates that the receive buffer is fi lled to
75% (see XON/XOFF).
CTS high indicates that the unit transmitting the CTS signal
is ready to receive data. CTS low indicates that the receive
buffer is full (see XON/XOFF). In some computer programs,
for example MS
Windows Terminal, RTS/CTS is designated
“Hardware.”
