- 134 -37. APPENDIX A – SETTING A BARCODE SCANNER1. RADWAG scales use RS232 interface with transmission in onedirection to communicate with a barcode scanner. It requires only twowire connection. So barcode scanners needs to be equipped withRS232 with disabled hardware and software flow control.2. Both the terminal and a scanner can have transmission parametersset. Both devices should have set the same parameters: baud rate,data bits, parity control, number of stop bits. e.g. 9600,8,N,1 – baudrate 9600 bit/s , 8 - data bits, no parity control, 1 stop bit. By default inPUE5 barcode scanner needs to be connected to COM3 – with baudrate 9600 bit/s.3. Barcode scanners can send additional information apart from abarcode e.g. barcode symbology. As RADWAG devices do not usethis information it is advisable to disable it.4. Some RADWAG systems can omitted some inessential informationin the code by setting parameters outlining the beginning and lengthof the analyzed code.5. In order to have a barcode read by PUE5 it is required to program anappropriate prefix and suffix. The prefix is (1 byte) 01 hexadecimallyand the suffix is (1 byte) 0D hexadecimally.6. Different barcode scanners allow to disable/enable reading differentbarcode symbologies.7. Barcode scanners can be programmed by reading differentprogramming codes present in their programming manuals.8. Barcode scanners bought together with RADWAG systems areproperly configured and tested.Barcode coded hexadecimally with prefixand suffixBarcode in ASCII code(omitted controlcharacters)Symbology01 30 30 32 31 30 31 32 36 0D 00210126 EAN-801 30 31 32 33 34 35 36 37 38 39 0D 0123456789 2 of 501 43 4F 44 45 20 33 39 20 54 45 53 54 0D CODE 39 TEST CODE 3901 31 31 30 31 32 33 34 35 36 37 38 39 31 0D 1101234567891 EAN-1301 43 6F 64 65 20 31 32 38 20 54 65 73 74 0D CODE 128 Test CODE 128
