Paxar Gold 6037EX manual A n n e r s, Using the Scanners

S c a n n e r s

Each printer comes with either of two bar code scanners.

♦SE-923

♦SE-923HS

Using the Scanners

To use the either scanner, the application must

1 . Enable the scanner with scnOpenScanner or scnOpenScannerShared. scnOpenScanner takes over the printer’s serial port (preventing other RS-232 communications), but scnOpenScannerShared shares the port. Therefore, when using scnOpenScanner, the application should disable the scanner immediately before serial communications and enable it immediately afterwards. To avoid processing delays, use scnOpenScannerShared when possible.

2 . Configure the scanner (optional). To learn how to configure the scanner, see the appropriate scn functions in Chapter 4, “Function Reference”.

3 . Call various scanner functions, such as scnGets.

4 . Close the scanner with scnCloseScanner.
