(SN) Scanner Configuration –
This command configures the optional linear scanner, as follows:
Values Scanner Configuration Range / Interpretation
Bar Code Type – Specifies the bar code, using two digits, followed by ‘
Y
’ (to enable) or
‘
N
’ (to disable) the code, where:
01 = CODE 39
02 = IATA
03 = CODABAR
04 = INTERLEAVED 2 OF 5
05 = INDUSTRIAL 2 OF 5 06 = CODE 93
07 = CODE 128
08 = MSI/PLESSEY
09 = EAN(13/8)
10 = EAN(13/8)+2 11 = EAN(13/8)+5
12 = UPC(A/E)
13 = UPC(A/E)+2
14 = UPC(A/E)+5
B
Note: To maximize throughput and decoding integrity enable only those symbologies that will
be read.
C
Bar Code Count – Specifies the number of codes to be read, where:
00 – 99 (00 = Auto [variable] mode, counting those codes present)
Note: Do not use Auto Mode with bitmapped codes or codes with certain addendums; see
Appendix F.
H
Min Readable Height – Sets the vertical distance of the code that must have identical
reads to pass, where:
1 = 1/16
2 = 2/16
3 = 3/16
4 = 1/4
5 = 1/2
0 = Disabled (defaults to Redundancy Level, 2x)
Note: The specified distance should not exceed 50% of the measured bar code height.
M
Mode – Enables detection of the scanner by the printer, where:
A = Auto (automatically senses presence); Y is also a valid enabler.
E = Enabled (if presence is not detected a fault is generated).
D = Disabled (the scanner is disabled); (N is also a valid disabler.)
Redundancy Level – An alternative data integrity method, where the selected level sets
the number of consecutive, identical decodes required to pass the bar code. If differing
values are read, the count is restarted.
0 = Auto Mode
1 = read code 1X
2 = read code 2X
3 = read code 3X
4 = read code 4X
5 = read code 5X 6 = read code 6X
7 = read code 8X
8 = read code 10X
9 = read code 12X
A = read code 15X
B = read code 20X C = read code 25X
D = read code 30X
E = read code 35X
F = read code 40X
G = read code 45X
V
Note: Depending upon the print speed, higher levels may cause erroneous failures when
scanning multiple or small bar codes.
Table 5-11: Scanner Configuration Set Command
Example:
<STX>KcSNC00H4MAB12YV0<CR>
(The above sample sets the printer to sense the scanner automatically, to read a variable
number of UPC bar codes, and to pass only those codes where ¼ inch of the bar code has
identical reads.)
