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.
7-bit

NOTE Parity of None is not valid when Data Bits is set to 7-bit.
