597 +
598 +The following uses the default interrupt triggering mode (% style="color:blue" %)**(AT+INTMOD=2)**(%%) as an example to show the interrupt function of (% style="color:blue" %)**INT**(%%):
599 +
600 +When a high voltage is given to the INT pin and then the level of the (% style="color:blue" %)**INT**(%%) pin changes from high to low, the interrupt is triggered by a falling edge and the RS485-LN sends an uplink data.
601 +
602 +(% style="color:red" %)**Note: The level that triggers the interrupt ranges from 3.3V to 24V. Generally, it is recommended to use less than 12V.**
603 +
604 +**Example:**
605 +
606 +* Use a dry contact to connect the (% style="color:blue" %)**INT**(%%) pin and (% style="color:blue" %)**VIN+**(%%) pin of the RS485-LN.
607 +
608 +When the dry contact is closed, INT and VIN+ conduct and INT is high.
609 +
610 +Disconnecting the dry contact, the level of the INT pin changes from high to low, triggering an interrupt (triggered along the falling edge), and the RS485-LN sends an uplink data.
611 +
612 +[[image:image-20240925174124-5.jpeg||height="439" width="703"]]
613 +
614 +* Use a regulated power supply or a wet contact to connect the 485-LN to trigger the interruption.(This section uses a regulated power supply as an example.)
615 +
616 +The positive pole of the stabilized power supply is connected to the (% style="color:blue" %)**INT**(%%) pin of RS485-LN, and the negative pole of the stabilized power supply is connected to the (% style="color:blue" %)**VIN-**(%%) pin of RS485-LN.
617 +
618 +When the regulated power supply is operating, a high voltage is given to the INT pin and the INT level is high. When the regulated power supply is turned off, the level of the INT pin changes from
619 +
620 +high to low, at which time an interrupt is triggered (triggered along the falling edge), and the device will send an uplink data.
