Note: If you are using the 2D 520-RF then refer to the 2D setup chart starting on page 24.
Postamble
"Postamble" refers to a user-specified data string transmitted at the end of each bar code. For instance, if you
specify the postamble
@@
and read data of
123456
, "
123456@@
" would be transmitted to your computer.
The default is no postamble. To select a postamble, scan up to 15 characters from the "FULL ASCII MENU"
on the back of the
Reader Setup Menu
, and then scan
SET
when you're done. To return to the no postamble
setting, scan
CLEAR
here instead of scanning
SET
or any characters from the FULL ASCII MENU.
You can
trim 1-15 trailing characters
from bar code codes by scanning a
~
(tilde -- ASCII 126) followed by a
single hex digit,
1
through
F
. (Bar codes which are shorter than the amount-to-trim are transmitted without
trimming.) Consider the examples in the following table to understand the options of the Postamble:
Bar Code Data
Postamble
Data Transmitted
123
XYZ
123XYZ
12345678
~3XYZ
12345XYZ
12345678
~9
12345678
12345
~A
12345
123456
~5
1
Bar codes that are shorter than the sum of the Postamble trimming and Preamble trimming will be transmitted without
trimming. Selective trimming and min/max bar code data is also supported through Postamble specifications, (See
Preamble
above for complete details).
Characters
This setup option allows you to output ASCII characters different from the ones scanned.
For example
: Suppose you want to output a hex 92 character every time you scan a 1 (hex 31); you want to
remap hex 31 to hex 92, (If you're using 8 data bits, output of 80-F8 codes is possible.)
1) Scan the
Start Setup
Bar Code
2) Scan the
Characters
Bar Code on the Setup Sheet.
3) Scan
3 1
and
9 2
to output hex 92 when reading a "1".
4) Scan up to 7 other pairs of character reassignments.
5) Scan
Set
when complete.
6) Scan
End Setup
to exit setup mode.
Hex values for each character code are shown on the
Full ASCII Menu
. The equivalent decimal values are
also shown for each character.
You can also eliminate characters by reassigning hex codes to FF. For example, to strip all $ (dollar sign)
characters from transmission, you would follow the above instructions and scan
2 4 F F
in step 3.
Reset
Once you are in the Setup Mode, don't scan
Reset
unless you're sure you want to restore the RF Laser to its
default settings (as described on
page 5
), erasing all changes you've made.
