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 languages
to be used. Refer to the Intermec Fingerprint v7.xx Reference
Manual for information on which characters 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

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 communication is controlled 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".
