43. APPENDINX E - Settings of ZEBRA printers

Baud rate – 9600b/sec
Parity control – none
Bits – 8bit
Stop bits – 1 bit
Data on a printout from a printer regarding RS 232:
Serial port : 96, N, 8, 1
Means of activating an information (test) printout and carrying out changes in
printer's settings is specified in a user manual of ZEBRA printers.
44. APPENDIX F – Communication with barcode scanners
1. For communication with barcode scanners RADWAG balances 3Y series use
RS232 interfaces and simplex transmission (one direction) without
handshaking. Only two wires are required for assuring such a transmission.
Therefore, used scanners should be equipped in such interface with disabled
both hardware and software handshaking.
2. Both balances and scanners have the possibility of setting of transmission
parameters. Both devices are required to have the same parameters set :
baud rate, number of data bits, parity control, stop bits. e.g. 9600,8,N,1 –
baud rate 9600 bit/s , data 8-bits, no parity control, 1 stop bit.
3. Barcode scanners can send additional information apart from the expected
barcode e.g. type of barcode. It is advisable to disable such information
because RADWAG devices and software do not use it.
4. Some RADWAG systems can omit unnecessary information by using
parameters that mark the beginning and the length of the code required to
analyse.
5. Should a barcode be recognized by a balance, it needs to have some
particular features. A code requires programming a characteristics prefix and
suffix. In a standard accepted by RADWAG, a prefix is a sign (byte) 01
hexadecimal and a suffix is a sign (byte) 0D hexadecimal.
6. Most barcode scanners allow to enable/disable different barcode types.
7. Programming of scanners is usually performed by reading special barcodes
or by using an external software tool.
