A new change to c9 smartens up it's barcode scanner integration so c9 is able to detect when you have used a barcode scanner and it handles part adding in a way that makes sense for barcode scanning as opposed to manually keying in the part number.  C9 will add one onto the invoice straight away. If part was already scanned, it will increment the quantity of that part.

To enable this you need to configure transmission of STX  on your barcode scanner. Your barcode also requires transmission of either ETX or a enter key at end of the barcode scan.  Generally recommend enter key though there are some circumstances where you may prefer ETX. This cover enter key only, which generally barcode scanner will do out of the packaging anyway.

STX = Start transmission (0x0b Hex or Ctrl+B).

See your barcode user manual on how to do this. For example for the barcode scanner with model MJ-4209.  The user guide which you print out contains barcodes to scan to program the barcode scanner. So print this and scan the below codes to enable STX.

This assumes that the barcode scanner will transmit the following:  the STX, then the barcode then Enter key
