Intermec EasyCoder 501 XP & 601 XP – Service Manual
Bar Code Wand Interface (P35)
The printer was originally prepared for connection of a bar code
wand via a connector (P35) 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 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 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 the serial port.
