Bar Code Wand Interface
The printer was originally designed for connection of a bar code
wand or scanner via a connector on the CPU board accessible
through a slot in the printer’s rear plate.
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 single parameter or a combination
of up to 3 or 4 setup parameters. Refer to the
EasySet Bar Code
Wand Setup manual for more information on how to produce
setup bar codes.
The printer will acknowledge that a bar code has been success-
fully read 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
than Code 128, choose a regular bar code scanner from Inter-
mec’s wide product range and connect it to the serial port.
