Default:
A standard option or parameter setting. Default settings are present in the memory of
a device. If no other value or option is chosen within a program (or bar code menu),
the default settings are automatically chosen.
Disable:
To disable an option means, to deactivate.
ECC:
An acronym for Error Correction Code. See error correction.
ECI:
An acronym for Extended Channel Interpretation. This refers to a method used in
2-dimensional bar codes to encode characters in other code sets then ASCII.
Emulation:
The imitation of all or part of one device by another so that the mimicking device can
accept the same data and perform the same functions as the actual device.
Enable:
To enable an option means, to activate it.
Error correction:
The possibility to correct read errors in a bar code. Most 2D bar codes have extra
information that allows correction of the bar code. This makes it possible to read
(partly) damaged bar codes.
Fixed length:
Relates to a symbol in which the data elements must be of specific length.
Flow control:
See handshaking.
Format:
A message or data structure that allows identification of control and data parts by their
position within a frame.
Handshaking:
The initial exchange between two data communication systems prior to and during
data transmission. The first unit sends a signal, then waits for an appropriate signal in
response. A handshake method (such as XON/ XOFF), parity setting, number of data
bits, and number of stop bits.
