Code 39 Options - Allen-Bradley 2755-HDG-4 User Manual

Configuring the Scanner 3–9

Code 39 Options

The following options are available for Code 39 symbols.
Code 39 Check Digit
When enabled, the scanner verifies the Code 39 check digit (modulo 43
check character).
Code 39 Buffering (Scan and Store)
When enabled, the scanner stores all Code 39 symbol data that has a
leading space as the first character (following start pattern). As Code 39
labels are scanned for buffering, the scanner provides a high/low beep to
indicate that the data is stored in the buffer.
Up to 250 bytes of information may be stored. If you scan a symbol and
the buffer is full, the scanner will provide three long high tone beeps. No
transmission will occur and the data in the buffer is not affected.
Note: Before you can disable Code 39 buffering, you must clear the
buffer (see below).
Clear Transmission Buffer
Clears the Code 39 transmission buffer. You will hear a high/low/high
beep after the buffer has been cleared. No data is transmitted.
