Scan Data Format
This parameter allows you to change the scan data transmission format. Double-tapping on
Scan Data Format displays the following options from which you can choose a data format:
data (as-is), data [S1], data [S2], data [S1][S2], [P] data, [P] data [S1], [P] data [S2], and
[P] data [S1][S2] .
Prefix [P], Suffix [S1] And Suffix [S2]
A prefix and/or one or two suffixes may be appended to scan data for use in data editing.
When you double-tap on these parameters, a dialog box is displayed in which you can enter
a value from
0 to 255 .
Delete Char Set ECIs
Setting this parameter to on enables the scanner to delete any escape sequences representing
Character Set ECIs – Extended Channel Interpretations (also known as GLIs) – from its
buffer before transmission.
When this parameter is enabled, the scanner transmits data from PDF417 and MicroPDF417
bar codes containing Character Set ECIs, even when the ECI Protocol is disabled.
ECI Decoder
Setting this parameter to on enables the scanner to interpret any Extended Channel Interpre-
tations (ECIs) supported by the scanner. This parameter has no effect on symbols that were
not encoded using ECIs.
If this parameter is set to
off and a symbol that was encoded using an ECI escape is scanned,
the scanner transmits the ECI escape followed by the data that was not interpreted.
C.1.5 Code 39
Enabled
Setting this parameter to on enables Code 39.
Enable Trioptic Code 39
Trioptic Code 39 symbols always contain six characters. Setting this parameter to on allows
this type of symbology to be recognized.
Note: “Trioptic Code 39” and “Full ASCII” should not be enabled simultaneously. The
scanner does not automatically discriminate between these two symbologies.
