602 +
603 +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.
604 +
605 +(% 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.**

608 +
609 +* Use a dry contact to connect the (% style="color:blue" %)**INT**(%%) pin and (% style="color:blue" %)**VIN+**(%%) pin of the RS485-LN.
610 +
611 +When the dry contact is closed, INT and VIN+ conduct and INT is high.
612 +
613 +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.

620 +
621 +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
