using serial trigger source: 
the ”TRIGGER” LED is not 
blinking. 
  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? 
Phase Mode: 
the ”TRIGGER" LED is 
correctly blinking but no image 
is displayed in VisiSet™ 
Calibration Tool window. 
  Is the Phase frequency lower than the maximum frame 
rate? 
Continuous Mode:

blinking. 
  Verify the correct software configuration settings. 
Any Operating Mode: 
the ”TRIGGER” LED is 
correctly blinking but no result

the No Read Message 
  Run the Rapid Configuration procedure in chapter 1. 
  Position the reader as described in par. 3.3 and through 
the VisiSet™ Calibration Tool:

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. 
Communication: 
reader is not transmitting 
anything to the host. 
  Is the serial cable wiring correct? 
  If using CBX, be sure the RS485 termination switch is 
OFF.
