TROUBLESHOOTING
Problem
One Shot or Phase Mode
using serial trigger source:
the "TRIGGER" LED is not
blinking.
Phase Mode:
the "TRIGGER"
correctly blinking but no image
is displayed in the DL.CODE
window.
Continuous Mode:
the "TRIGGER" LED is not
blinking.
Any Operating Mode:
the "TRIGGER"
correctly blinking but no result
is transmitted by the reader at
the end of the reading phase
collection.
Image not clear:
Image focused
decoded:
Reading:
the reader always transmits
the No Read Message
Communication:
reader is not transmitting
anything to the host.
TROUBLESHOOTING GUIDE
Suggestion

On the Reading Phase step check the settings for
Acquisition
Reading Phase-OFF parameters.

Are the COM port parameters (Baud Rate, Parity, Data
Bits, Stop Bits) correctly assigned?

On the Reading Phase step check the settings of
Acquisition Trigger String, Reading Phase-ON
String, and Reading Phase-OFF String parameters.

Is the serial trigger source correctly connected?

Is the Phase frequency lower than the maximum frame
LED is
rate?

Verify the correct software configuration settings.

Check the Code Collection parameters on the Reading
LED is
Phase step and the Data Formatting parameters on the
Data Formatting step.

verify the Focus procedure

but not verify the Calibrate Image Density procedure.

Run the Rapid Configuration procedure in chapter 1.

Position the reader as described in par. 3.3 and through
DL.CODE:

Tune the Acquisition Delay on Trigger, if the moving
code is out of the reader field of view;

Set the Continuous Operating Mode if no external
trigger source is available;

Tune the Image Setup to improve the code image
quality;

Check the parameter settings in the Code Setup
step: 2D Codes, 1D Codes, and Postal Codes;

View the full resolution code image to check the
printing or marking quality.

Is the serial cable wiring correct?

If using CBX, be sure the RS422 termination switch is
OFF.

Are the host serial port settings the same as the reader
serial port settings?

In DL.CODE Device menu > Settings > Settings > LED
Configuration,
configured to indicate Main Serial Port TX or Main
Serial Port RX.
