If the image from your Datalogic Card Reader is not clear, verify the Focus procedure and reading distance.
What to do if my Datalogic Matrix 120 always transmits the No Read Message?
If your Datalogic Card Reader consistently transmits the No Read Message, try the following: 1. Run the Rapid Configuration procedure. 2. Position the reader correctly using the guidelines. 3. Adjust the Acquisition Delay on Trigger if the moving code is out of view. 4. Set the Continuous Operating Mode if no external trigger is available. 5. Improve code image quality through Image Setup. 6. Check parameter settings in the Code Setup step for 2D Codes, 1D Codes, and Postal Codes. 7. View the full resolution code image to assess printing or marking quality.
What to do if Datalogic Scanner always transmits the No Read Message?
If your Datalogic Scanner is consistently transmitting a 'No Read Message', try the following: * Run the Rapid Configuration procedure. * Position the reader as described in “Mounting And Positioning Matrix 120”. * Tune the Acquisition Delay on Trigger through DL.CODE 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 Settings to improve the code image quality. * Check the parameter settings in the Advanced Setup step: 2D Codes, 1D Codes, and Postal Codes. * View the full resolution code image to check the printing or marking quality.
Why is my Datalogic Matrix 120 not transmitting data to the host correctly?
If the data transferred to the host from your Datalogic Card Reader is incorrect, corrupted, or incomplete, ensure the host serial port settings match the reader's. Also, in DL.CODE Data Formatting, verify the Header and Terminator String parameters and check the Message Field parameter settings.
How to fix Autorun or Start.hta when it doesn't run during Datalogic Scanner DL.CODE Installation?
If Autorun or Start.hta doesn't run during DL.CODE installation for your Datalogic Scanner, check your Windows settings to see if Autorun is disabled. Also, associate the file type .hta with the Microsoft HTML Application host mshta.exe in Windows\System32.
What to do if the ECM driver fails to install correctly for Datalogic Scanner?
If the ECM driver fails to install correctly for your Datalogic Scanner, and you are using Windows 7, ensure that update KB3033929 is installed.
What to do if TRIGGER LED is blinking but no image is displayed in DL.CODE for Datalogic Scanner?
If the TRIGGER LED is correctly blinking but no image is displayed in the DL.CODE window for your Datalogic Scanner, check if the Phase frequency is lower than the maximum frame rate.
Why is the TRIGGER LED not blinking when using serial trigger source on Datalogic Scanner?
If the TRIGGER LED is not blinking when using a serial trigger source on your Datalogic Scanner, check these items: * Confirm the COM port parameters (Baud Rate, Parity, Data Bits, Stop Bits) are correctly assigned. * Verify the settings for Acquisition Trigger, Reading Phase-ON, and Reading Phase-OFF parameters in the Reading Phase step. * Check the settings of Acquisition Trigger String, Reading Phase-ON String, and Reading Phase-OFF String parameters in the Reading Phase step. * Ensure the serial trigger source is correctly connected.
How to improve image clarity on Datalogic Scanner?
To improve image clarity on your Datalogic Scanner, verify the Focus procedure and reading distance.
Why Datalogic Scanner doesn't transmit results even when TRIGGER LED is blinking?
If the TRIGGER LED on your Datalogic Scanner is blinking but no result is transmitted, verify the Code Collection parameters in the Reading Phase step and the Data Formatting parameters in the Data Formatting step.
