Useful Application Program
Bar2Key
The 4210's built-in scanner is connected to the COM3 port. Applications written
for the 4210 should therefore call PSC's scanner DLL library (please refer to the
4210 SDK/Programming Manual for detailed functions of the DLL library). Some-
times, however, it is not easy for the user to get scanned data into the user's
application program, especially if the application has been provided by a 3
rd
party
and user modification of the source program is not allowed. In this situation use
Bar2Key.exe.
"Bar2Key.exe" is a useful tool for users to get scanned data into any application
program. While it is running, all scanned data will be routed to a standard key-
board input buffer. In other words, scanned data will be treated as keyboard
input. Thus, any application program can receive scanned data as if it were input
by the keyboard.
Locate "Bar2Key.EXE" in the \Windows folder. After
executing it, a Barcode icon will appear on the taskbar.
Then press the scanner trigger key to scan the barcode
label.
In order to exit Bar2Key.exe, double tap the Barcode icon
on the taskbar and then tap the Exit button.
For detailed barcode symbology settings, please refer to
the next section.
BarSetup
When it is necessary for the user to change the default barcode symbology for a
different application, BarSetup provides the ability to change default symbology,
place delimiter characters behind scanned data, and save the settings.
Run this program from \Windows\BarSetup.exe and two buttons will be dis-
played: "Barcode Symbologies" and "Delimiter".
