What to do if the TRIGGER LED is not blinking on Datalogic Measuring Instruments?

If the 'TRIGGER' LED isn't blinking while the External Trigger is switching in One Shot or Phase Mode using Input 1 or Input 2, verify the connection to either the 25-pin connector or the CBX spring clamp connectors. Ensure the sensor is properly connected to Input 1 or Input 2 and that the photo sensor is receiving power. For NPN, confirm power is supplied to one of the I1 or I2 signals (A or B). For PNP, ensure one of the I1 or I2 signals is grounded. Check the photo sensor LEDs and sensor/reflector alignment. Also, review the EXTERNAL TRIGGER or INPUT 2\Debounce Filter parameter in the Digital I/O folder, and the Reading Phase-ON, Acquisition Trigger, and Reading Phase-OFF parameters in the Operating Mode folder.
