M-9-5 Bar Code Configuration Mode
Definition:
Serial Cmd:
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 Omron 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.
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.
M-16
Bar Code Configuration Mode is a way of programming the reader by
using ECC 200 Data Matrix symbols.
