4 - 10 LI2208 PRODUCT REFERENCE GUIDE
Data Bits (ASCII Format)
This parameter allows the linear imager to interface with devices requiring a 7-bit or 8-bit ASCII protocol.
Parity
A parity check bit is the most significant bit of each ASCII coded character. Select the parity type according to
host device requirements.
•
Select Odd parity and the parity bit value is set to 0 or 1, based on data, to ensure that an odd number of
1 bits are contained in the coded character.
•
Select Even parity and the parity bit value is set to 0 or 1, based on data, to ensure that an even number
of 1 bits are contained in the coded character.
•
Select None when no parity bit is required.
NOTE When 7-bit is selected, Parity must be set to Odd or Even. If Parity is set to None, the scanner
automatically operates in 8-bit mode, even if 7-bit is scanned.
