Barcode Reader

Hi All,

I am using Dragon DR101LR Barcode scanner to read barcode to IM151-7 CPU. I used FB2 in step-7 to read barcode value. I am using RS232-485 converter between Scanner and CPU. But I received only length from scanned data.

But on RS232 connections CPU reads lenght as well as some value in HEX. But this reads wrong value always. Every Scan gives other value.

For Barcode Reader I tried- 003 number in Code39 and Code128A format.

I am not getting why CPU reads different value & length at every scan.

All your solutions are highly appreciated.

Thanks in advance!
