Barcodes for terminating character I. Preamble and Postamble A. Using the table Each character you want to output will be listed in the ASCII table. The coordinates of this table will tell you what two-digit sequence to enter. The column of the character is first digit. The row of the character is second digit. B. Example You can modify the barcode scanner to enter characters before or after the scanned-in data. For example, to enter 'Me' for preamble: M: column is "4" row is "D" e: column is "6" row is "5" “4D65" will need to be scanned in the hexidecimal barcodes. Here is the full procedure for doing so: Scan "Enter group". Scan "Preamble". Scan "4D65" from the Hexidecimal barcodes. Scan "Confirm" from the Hexidecimal barcodes. Scan "Exit". “Me” will be output before any product information that is scanned in. The postamble function will append characters. To clear the preamble: Scan "Enter group". Scan "Preamble". Scan “Clear”. Scan "Exit". C. Troubleshooting tips You can test the scanner by plugging it into a windows computer, opening notepad, and scanning the barcodes. It will enter data like a keyboard. If any problems are encountered, try unplugging and plugging the scanner back in. D. Character table E. Hexidecimal Barcodes II. Setting the terminator. A. Scan “Enter group”.
