MSI Plessey check Digit
When enabled, one or two digits at the end of the bar code that
checks the integrity of that data.
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. 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. The leading space is not stored in the
buffer.
Decoding of a valid Code 39 symbol with no leading space causes
transmission in sequence of all buffered data in a first-in, first-out
basis, plus transmission of the triggering symbol.
If you select the scan and transmit option, decoded Code 39 symbols
without leading spaces are transmitted without being stored in the
buffer.
Scan and Store affects Code 39 decodes only. If you select Scan and
store, it is recommended that you configure the scanner to decode
Code 39 symbology only.
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.
Beeper Volume
Allows you to select the level of beeper volume.
