TROUBLESHOOTING GUIDE
Suggestion
• In the Operating Mode folder check the settings for
Reading Phase-ON, Acquisition Trigger and
Reading Phase-OFF parameters.
• Are the COM port parameters (Baud Rate, Parity, Data
Bits, Stop Bits, Handshake) correctly assigned?
• In the communication folder, check the settings of
Reading Phase-ON String, Acquisition Trigger
String and Reading Phase-OFF String parameters.
• Is the serial trigger source correctly connected?
•
Is the Phase frequency lower than the maximum frame
rate?
• Verify the correct software configuration settings.
• In the Data Collection folder check the settings for the
CODE COLLECTION, DATA FORMAT and
STATISTICS parameter groups.
• verify the Focus procedure
• verify the Calibrate Image Density prodcedure.
• Perform the Rapid Configuration procedure in chapter 1.
• Position the reader as described in par. 3.3, par. 7.1
and through the VisiSet™ Calibration Tool:
−
Tune the ACQUISITION TRIGGER DELAY, 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 ACQUISITION SETTING to
improve the code image quality;
−
Check the parameter setting in Decoding,
2D Codes, 1D Codes, and Postal Codes folders;
−
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 RS485 termination switch is
OFF.
• Are the host serial port settings the same as the reader
serial port settings?
•
In VisiSet™ Digital I/O folder, "COM" LED can be
configured to indicate MAIN COM port TX or MAIN
COM port RX.
• Are the host serial port settings the same as the reader
serial port settings?
