2-10 Programmer’s Manual
Scanner Function Overview
The scanner contains a buffer to hold the data from a scan.
The application should contain a buffer of its own if it needs to
save the data before scanning again. Processing works as
follows:
1. Initiate the scan, putting the data in the scanner buffer with
either scnGets or scnTrigger.
2. Either:
♦ Process the data directly in the scanner buffer with
scnGetch, scnGetche, scnGetBarCodeType, or
scnScannerHit.
♦ Save the data in the application buffer with scnGets
(continued from step 1) or scnGetScannedData.
The application buffer must be one byte
longer than the largest string that you may
scan.
3. If needed, process the data in the application buffer.
NOTE: Every bar code that the SE-923 scanner is configured
for delays boot-up by .7 seconds. This does not apply
to the SE-923HS scanner.
