Bar Code Configuration
Bar Code Configuration
Bar code configuration can be entered three different ways:
1. By forcing the reader into bar code configuration mode by serial command
<BCCFG> .
2. By configuring one of the 4 EZ button positions to bar code configuration mode.
3. By reading a Data Matrix symbol with a special code word used by ISO/IEC 16022
to signify reader programming. This can be either in a regular read cycle or in read
rate. Reading this symbol in the calibration routine will have no effect.

Once Bar Code Configuration mode has been entered, the Data Matrix symbols can be
thought of as serial data. You can configure the reader by printing labels in Microscan’s
serial command format. Commands are processed as if the data were streamed in
through the serial port. The reader will acknowledge the symbol with a beep, green flash,
and echo the serial data to the host. If the command causes the reader to produce more
serial output such as serial verification or counter requests, the data will be routed to the
host port.
The Bar code configuration mode can be exited by any reset <A> or <Z> command as
well as a <J> or a quick press and release of the EZ button.
The command to exit bar code configuration can be included as part of the bar code, for
example, encoding
<K200,4><K220,1><J> into a Data Matrix symbol. This would configure
the reader to serial trigger mode, program a new trigger to end the read cycle, and exit the
bar code configuration mode with the
<J> .
To end all EZ button functions, press the EZ button and quickly release.
Definition:
Bar code configuration is a way of programming the reader by using Data
Matrix ECC200 symbols.
Serial Cmd: <BCCFG>
1. In normal reading modes, it is required to read a special Data Matrix symbol with a special codeword used by
ISO/IEC 16022 to signify reader programming.
