Use Your FuzzScan
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/NG Signals
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.
