System Setup
Description of Operation
A barcode reader is used to scan barcodes of 8 numerical digits. The scanned data is sent to the FC6A Series MicroSmart through
the Serial Port 1 (RS232C) and stored to data registers. The upper 8 digits of the data are stored to data register D20 and the
lower 8 digits are stored to data register D21.
Setting User Communication Mode in WindLDR Function Area Settings
Since this example uses the Serial Port 1 (RS232C), select User Protocol for Port 1 in the Function Area Settings using WindLDR.
See "Programming WindLDR" on page 5-25.
Setting Communication Parameters
Set the communication parameters to match those of the barcode reader. See "Programming WindLDR" on page 5-25. For details
