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 v8.3x, Programmer’s Reference Manual
for more information.
• 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 is a protocol where the communication is controlled by cur-
rents 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 Termi-
nal, RTS/CTS is designated “Hardware.”
ENQ/ACK is a protocol where the communication is controlled by
the control characters ENQ (ASCII 05 dec.) and ACK (ASCII 06 dec.)
being transmitted on the same line as the data. The sending unit trans-
mits ENQ at regular intervals. If the response ACK is not received, the
