Operating Modes
The wizard offers the following Operating modes:
On Line Operating Mode
This operating mode causes the reader to be connected to an external Presence Sensor using EXT TRIG+ and EXT
TRIG- inputs.
During the active phase of the presence sensor, the scanners try to acquire and correctly decode the code.
In case the decoding phase is successful, the barcode characters are transmitted on the serial interface. Otherwise, a
no read message is sent.
Automatic Operating Mode
This operating mode does not require the connection to an external Presence Sensor.
When working in this mode the reader is continuously scanning, while the reading phase is activated each time a
barcode enters the reader reading zone. The reader stops reading after an N number of scans without a code.
Barcode characters are transmitted on the serial interface. In case of a failed reading phase no message is sent to the
host computer.
Test Operating Mode
This operating mode causes the reader to be continuously activated allowing to verify its reading features and its
reading position with respect to the barcode. For this reason, it is particularly advised during the installation phase of
the reader.
After 100 scans, the values relative to an internal counter and the decoded code are displayed and transmitted on the
serial interface. The counter reports the percentage of good reads of the label.
NOTE
This operating mode is not used for SYNCHRONIZED network configurations.
The following Operating Mode is not included in the Wizard but can be selected from the Operating Mode parameters:
Continuous Operating Mode
The reading phase is always active and, differently from the Automatic operating mode, it also allows reading two or
more codes when placed along the same scan line.
Code transmission is identical to the other operating modes except that there is no transmission on the serial port in
case of a No Read condition.
