14.4 Bar Code Wand Interface

The printer has a socket (J59) 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. The bar code wand interface is not supported by IPL.
If the 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 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 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. 36 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 Intermec's wide product
range and connect it to a serial port.
