Bar Code Wand Interface (P35)
The printer is prepared for connection of a bar code wand via a
connector on the CPU board accessible through a slot in the print-
er's rear plate. The bar code wand is primarily intended for read-
ing Code 128 bar codes with setup information, but other types of
information could also be read.
If the Code 128 bar code contains FNC3, the data will be treated
as a setup string and will change the printer's setup accordingly. A
setup bar code may contain a combination of up to 3 or 4 setup
parameters. Each parameter is specifi ed by a setup id (for example
00 = "Ser-com,uart1,baudrate") and setup data. The setup data can
be a number referring to an item in a list of options (for example
05 = baudrate 9600), an unsigned number, or a signed number. A
checksum is calculated automatically.
Refer to the Intermec Fingerprint v7.xx Reference Manual for
more information on how to produce setup bar codes.
When a bar code has been successfully read, the printer will
acknowledge by emitting a short beep signal.
If no FNC3 character is found in the bar code, the data will be
stored in a buffer which could be read by specifying the "wand:"
device. The buffer is small, so it is recommended to use short bar
code data (max. 16 characters) and read the buffer regularly to
avoid overfl ow. For more demanding applications or for reading
bar codes other, choose a regular bar code scanner from Intermec's
wide product range and connect it to the serial port.
