Other Operational Serial Commands

The following serial utility commands can be entered from ESP's Terminal or a PLC:

File Source	Explanation
(Nothing)	All files in "root" directory
/	All files in "root" directory
/saved	All files in "saved" directory
*.*	All files in all directories
/del	Deletes all files in the root director
/saved/del	Deletes all files in the saved directory
del*.*	Deletes files in all directories

White Balance Calibration

<@WB>

The Quadrus MINI Velocity's factory default values are appropriate for nearly all applications. However, the White Balance calibration command will override the pre-configured values if necessary.

White Balance is a processing operation performed to ensure proper color fidelity in a captured digital image. The image sensor does not detect light in exactly the same way as the human eye, which means that some processing or correction of the detected image is necessary to ensure that the final image realistically represents the colors of the original image.

White Balance calibration works best if a white object (a piece of paper, for example) is placed in front of the imager. White and black objects can be present in the field of view during White Balance calibration, but no color objects can be present.

Bar Code Configuration Mode

Definition:	Bar Code Configuration Mode is a way of programming the imager by using ECC 200 Data Matrix symbols.
Serial Cmd:	<BCCFG>

Bar Code Configuration Mode can be entered three different ways:

• By forcing the imager into Bar Code Configuration Mode by serial command <BCCFG>.

• By configuring one of the 4 EZ Button positions to Bar Code Configuration Mode.

• By reading a Data Matrix symbol with a special code word used by ISO/IEC 16022 to signify imager 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 imager by printing labels in Microscan's serial command format. Commands are processed as if the data were streamed in through the serial port. The imager will acknowledge the symbol with a beep, green flash, and echo the serial data to the host. If the command causes the imager 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> 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 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 imager to enable Serial Trigger Mode, to program a new trigger to end the read cycle, and to exit Bar Code Configuration Mode with <J>.

To end all EZ Button functions, press the EZ Button once and quickly release.
