Automatic; Automatic/Trigger Object Sense; Test Mode - Datalogic Gryphon I GFS4100 Product Reference Manual

Serial Start Character (or String):
to activate the reading phase
Serial Stop Character (or String):
to stop the reading phase.
Phase Off Event:
The following selections are available:
•

•
Timeout:
ms in 20 ms increments.

Automatic

In Automatic mode, the scanner is continuously scanning. When a label enters the reading zone
and is decoded, no more decodes and reading phases are allowed until the label has left the
reading area. In order to guarantee identification of the code in the reading zone, a threshold
specifies the number of scans after the successful decode that the scanner will wait before
rearming the reading phase. The transmission of the decoded label depends on the
configuration of the Transmission Mode parameter.
Automatic mode configurations:
Automatic Threshold:
before the scanner switches back to a new reading phase.

Automatic/Trigger Object Sense

Automatic/TOS mode is the same as Automatic mode, but with the lighting system OFF. As an
object or barcode enters the reading area, the light is turned ON. The light will return OFF as
the reading phase is closed (see Automatic Mode above).

Test Mode

Test Mode reports information about the reading performance of the reader, and the code is
continuosly read. After 100 scans, the following information is transmitted to the Host:
•
•
The information can be displayed on the Host PC by running a terminal emulator program
such as HyperTerminal. The output data format is fixed.
