Parity
The parity decides how the fi rmware will check for transmission
errors. There are fi ve options:
• None (default)
• Even
• Odd
• Mark
• Space
Character Length
The character length specifi es the number of bits that will defi ne a
character. Eight bits allows more special characters and characters
specific for foreign laguages to be used. Refer to the Intermec
Fingerprint v6.14, 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 (default)
• 8 Characters ASCII 000 to 255 decimal
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
• 2 (default)
Flow Control
There are several ways to control the exchange of data (“handshak-
ing”) between the printer and the connected computer or other
device. Each option can be enabled or disabled separately, but
normally only one alternative should be enabled. For galvanically
insulated interfaces (that is, 20 mA current loop and RS-422),
ENQ/ACK or XON/XOFF are to prefer in order to retain interference
protection and to limit the number of lines.
