Bar Code Wand Interface

The printer has a socket on the CPU board for connecting a bar code
wand or scanner. The socket is accessible through a slot in the printer's
rear plate.
If a Code 128 bar code that contains the character FNC3 is read via this
port, the data will be treated as a setup string and will change the print-
er'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 successfully 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 overflow.
For more demanding applications or for reading bar codes other than
Code 128, choose a regular bar code scanner from Intermec's wide prod-
uct range and connect it to a serial port.
