EasySet Bar Code Wand
Intermec EasyCoder 601 XP – Service Manual Ed. 3
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 printer's
rear plate. The bar code wand is primarily intended for reading Code
128 bar codes with setup information, but other types of informa-
tion 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 specified by a setup id (e.g. 00 = "Ser-
com,uart1,baudrate") and setup data. The setup data can be a
number referring to an item in a list of options (e.g. 05 = baudrate
9600), an unsigned number, or a signed number. A checksum is
calculated automatically.
Refer to the Intermec Fingerprint 7.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 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, choose
a regular bar code scanner from Intermec's wide product range and
connect it to the serial port.
