Why is my Datalogic Matrix 210N Card Reader not transmitting data to the host?

Ensure the serial cable is correctly wired. If you're using a CBX, verify that the RS422 termination switch is OFF. Confirm that the host serial port settings match the reader's. You can also configure the COM LED Function in DL.CODE under Device menu > Settings > Settings > LED Configuration to indicate Main Serial Port TX or Main Serial Port RX.
