Reading Bar Code Labels

Bar code labels can contain data or commands. Each label must include start
and stop characters that provide initial timing references and direction of read
information to the coding logic. Intermec printers automatically generate
asterisks (*) as the start and stop characters.
Multiple-Read Labels
Multiple-read labels allow several labels to be stored in the reader buffer. The
reader transmits this data only after you scan the Enter label or a label that
does not begin with a space. Multiple-read labels have the format * DATA*,
with a space before the data. A multiple-read label looks like this:
Multiple-Read Label
* DATA*
* DATA*
When you scan a multiple-read label, the reader:
1. sounds one low beep,
2. adds the bar code data (minus the leading space character) to the
transmission buffer,
3. holds the data until receiving the transmit command.
Regular Labels
The reader transmits the data in a regular label as soon as it is scanned. Regular
labels have the format *DATA* with no space before the data. A regular label
looks like this:
Regular Label
*DATA*
*DATA*
When you scan a regular label, the reader:
1. sounds one high beep,
2. adds the label to the data buffer,
3. transmits the data as soon as it is received,
4. clears the data buffer.
