lengths, no decode will result. Entering data by keypad is not affected.
Postamble
Postambles are user-defined data that is attached to the end of data (bar code or keyed) that is transmitted to
the host by the RF Terminal. For example, if you set a Postamble of @@ and scanned bar code data of
12345, 12345@@ would be transmitted to the host.
• By default, the RF Terminal has no Postambles configured. Postambles can contain up to 15 characters.
To set a Postamble:
1 Select option “8” from the RF Terminal Setup menu then “2” for Postamble from the Other
Settings menu.
2 Enter the desired characters (up to 15). Pressing the shift key will turn the cursor red to indicate
that the shift is active. Pressing shift again will turn the cursor white and return to unshifted
mode..
3 Press “ENTER”.when you are finished entering data.
• To clear the Postamble and return to the default (no Postamble defined), press “CLEAR”.
• 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 (corresponding 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.
