3. Scan the SET bar code, or if using the keypad, press ENTER.
4. To clear the Postamble and return to the default (no
Postambles defined), scan CLEAR at step #2, and then
continue with your setup.
• You can use the Postamble to trim characters from the data you are
entering into the RF Terminal. You can trim from 1-15 characters from
the data by creating a Postamble of:
~x
where ~ is ASCII 126 and x is a single hex digit 1-F (correspon-ding to
1-15). Data that is shorter than the trim amount is transmitted without
trimming. Postambles trim characters from the end of the data. Here
are some examples:
Data Postamble Data Transmitted
123 XYZ 123XYZ
12345678 ~3XYZ 12345XYZ
12345678 ~9 12345678
12345678901 ~A 1
123456 ~5 1
Postamble trims trailing characters
• Using the Bar Code ID feature and the Postamble, you can trim data
selectively, trimming characters only on the bar code type specified.
To use selective trimming, enter:
~bx
where b is the Bar Code ID character (see the Code 128 setup
parameter) and x is the number of characters to trim from the end of
the data. For example, ~b2~c1 says “trim 2 characters from Code 39
data and 1 character from UPC-A data”. Remember that the
Postamble trims trailing data.
• Lastly, the Postamble can be used to check a maximum character length for
data entered. To check for length in the Postamble, enter:
|nnmm
where | is ASCII 124, nn is the two-digit minimum and mm is the two-
digit maximum. |0210 would check for a minimum of 2 characters and
a maximum of 10 If you try to scan a bar code outside the minimum or
maximum lengths, no decode will result. Entering data by keypad is
not affected.
