Sample Program – User Communication RXD
This example demonstrates a program to receive data from a barcode reader with an RS232C port using the user communication
RXD2 (receive) instruction.
System Setup
Description of Operation
A barcode reader is used to scan barcodes of 8 numerical digits. The scanned data is sent to the SmartAXIS through the RS232C
port 2 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 RS232C port 2, select User Protocol for Port 2 in the Function Area Settings using WindLDR. See
"Programming WindLDR" on page 10-4.
Setting Communication Parameters
Set the communication parameters to match those of the barcode reader. See "Programming WindLDR" on page 10-4. For details
of the communication parameters of the barcode reader, see the user’s manual for the barcode reader. An example is shown
