569		-Connect the Interrupt pin to RS485-LN INT port and connect the GND pin to V- port. When there is a high voltage (Max 24v) on INT pin. Device will send an uplink packet.
	578	+(% title="Click and drag to resize" %)​(%%)When there is a high voltage (3.3v and above, the maximum is 24V, but not more than 12v is recommended) on (% style="color:blue" %)**INT**(%%) pin. At this point, an interrupt is triggered and the Device will send an uplink packet.
570	570
	580	+**Example:**
571	571
	582	+* Use a dry contact to connect the (% style="color:blue" %)**INT**(%%) pin and (% style="color:blue" %)**VIN+**(%%) pin of the RS485-LN.
	583	+
	584	+When the dry contact is closed, INT and VIN+ conduct, and INT goes high, which triggers an interrupt, and the node sends an uplink data.

	586	+[[image:image-20240925164510-3.jpeg||height="414" width="656"]]
	587	+
	588	+* 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.)
	589	+
	590	+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.
	591	+
	592	+When the regulated power supply is turned on, given a high voltage to the INT pin, an interrupt will be triggered and the device will send an uplink data.
