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.
