The Preamble and Postamble apply to data entered in NON-PORTABLE MODE only. Upload Prefixes are used in programs for portable
data collection.
o Preambles are user-defined data that is transmitted at the beginning of data (bar code or keyed) that is entered in the TriCoder in
NON PORTABLE mode. For example, if you set a preamble of @@ and scanned bar code data of 12345, @@12345 would be
transmitted to the computer.
o Postambles are user-defined data that is transmitted at the end of data (bar code or keyed) that is entered in the TriCoder in NON
PORTABLE mode. For example, if you set a preamble of @@ and scanned bar code data of 12345, 12345@@ would be
transmitted to the computer.
o By default, the TriCoder has no preambles or postambles configured. Preambles and Postambles can each contain up to 15
characters scanned from the bar coded FULL ASCII Menu.
To set a preamble or postamble:
1. Press the 5 key at the Main Menu (opening screen)
2. Press the 7 key at the TRICODER SETUP screen
3. Select 1 for Preamble or 2 for Postamble.
4. Enter keys from the keypad or Scan any other desired characters (up to 15) from the FULL ASCII Menu (available on
the Utilities CD-ROM or from our website www.barcodehq.com/downloads.html).
5. Press the ENTER key on the TriCoder keypad to store the characters you want.
6. To clear the Preamble or Posta mble and return to the default (no P reambles or Postambles defined), key CLEAR
at step #4, then continue with your setup.
You can use the Preamble or Postamble to trim characters fro m the data you are entering into the TriCoder in NON
PORTABLE mode. The Upload Prefix and Suffix is used to trim data in portable mode (data co llection). You can trim from 1 -
15 characters from the data by creating a preamble or 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 a mount are
transmitted without trimming. Preambles trim data from the front; Postambles trim characters from the end.
Here are some examples, with and without trimming included:
