Bar Code Configuration Mode
Bar Code Configuration Mode can be entered in two different ways:
1. By forcing the reader into Bar Code Configuration Mode by serial command
<BCCFG> .
2. 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 during a
read rate test. 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 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.
Bar Code Configuration Mode can be exited by any reset <A> , <Z> or <J> command.
The command to exit Bar Code Configuration Mode can be included as part of the Data
Matrix symbol. For example, try encoding <K200,4><K220, 1 ><J> into a Data Matrix symbol.
This configures the reader to enable Serial Trigger Mode , to program a new trigger to end
the read cycle, and to exit Bar Code Configuration Mode with <J> .
Note: When the system is in barcode configuration mode, 2D symbols are allowed to pass
through even if the reader only has a 1D license. The system outputs a Config Code
Received message when the configuration symbol is decoded instead of showing the
configuration symbol’s actual symbol data. A > character is output to the Terminal to
indicate that the system is ready for bar code configuration mode.
Definition: Bar Code Configuration Mode is a way of programming the reader by
using ECC 200 Data Matrix 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.
