Use Your FuzzyScan
Both FuzzyScan
Barcode commands
and
Serial commands
are available
to configure your FM400. The FuzzyScan barcode commands are a series of
proprietary barcodes which allow you to easily configure the scanner for most
applications. Moreover, the FuzzyScan serial commands are ideal for precise
and complicated reading control in machine-controllable environments.
Please refer to the relevant documentations for details.
External Trigger and Serial Trigger
The FM400 provides both external trigger and serial trigger to activate the
scanning processes. Please note that the external trigger is available for
universal models only. The serial trigger is one of serial commands available
for all models including RS232 serial and USB COM Port Emulation
interfaces.
Scan Input Time-out
The scan input time-out is a preset light source on time available for
presentation, alternative and level modes. The scanner keeps the light
source on and continues to scan until the preset scan input time-out is up.
You can adjust the time-out duration from 100 milliseconds to 99 seconds to
meet various application demands.
OK and NG Outputs
The universal models provide additional OK and NG outputs for more precise
reading control. If the scanner got a good read, a signal will be outputted
through scanner OK pin. However, if the scanner failed to read the barcode
during a reading cycle or preset scan input time-out, a signal will be outputted
through scanner NG pin.
The OK and NG outputs are designed as
NPN
signal outputs and have been
preset to active low. If necessary, you are able to change the active state of
OK and NG outputs to meet your applications.
Operation Modes
The FuzzyScan FM400 series provides five different operation modes,
including trigger, alternative, level, presentation and force modes to meet
various application demands.
Both the presentation and force modes support
triggerless
operation, you
don’t need to use either external trigger or serial trigger to activate the
scanning. But the trigger, alternative and level modes
have to
work with
external trigger
or
serial trigger
to scan barcode.
