1. Introduction

The R718PC is a Class C type device based on the LoRaWAN open protocol of Netvox and is compatible with the LoRaWAN protocol.

The R718PC can transmit the serial port transparently and directly report the information received by the serial port to the corresponding gateway.

The serial port transparent transmission only supports RS-485 protocol.

LoRa Wireless Technology:

LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods,

LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless

communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main

features include small size, low power consumption, transmission distance, anti-interference ability and so on.

LoRaWAN:

LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different

manufacturers.

3. Main Characteristics

Compatible with LoRaWAN

DC 12V adapter power supply

Simple operation and setting

RS485 serial port transparent transmission

Supports up to 128 bytes data transmission

4. Operation

On/Off

Power on External 12V power supply

Turn on When the power is turned on, the indicator flashes once.

Restore to factory setting Press and hold the function key for 5 seconds till green indicator flashes for 20 times.

Power off Remove power

Note:

1. Five seconds after power on, the device will be in engineering test mode.

2. Remove and supply the power; the device is at off state by default. Need to be turned on to use.

3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other

energy storage components.

Network Joining

Never joined the network

(Or at factory setting )

Turn on the device to search the network.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

(Not at factory setting.)

Turn on the device to search the previous network.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Fail to join the network

(when the device is on)

First two mins: wake up every 15 seconds to send request.

After two mins: enter sleeping mode and wake up every 15 minutes to send request.

Note: Suggest to remove batteries if the device is not used to save power.

Suggest to check the device verification information on the gateway

or consult your platform server provider.

Function Key

Press and hold for 5 seconds Restore to factory setting / Turn off

The green indicator flashes for 20 times: success

The green indicator remains off: fail

Press once The device is in the network: Send recently received data (SensorRawCmdIndication),87(CmdID)+ReceiveData

The device is not in the network: the green indicator remains off

5. Data Report

The device will send a version package Report immediately after powering on the device.

The device has no operation until any configuration is done.

The device sends a down-link command configuration with LoRaWAN for the data that needs to be sent through the RS485 and sends the data

received by the RS485 to the gateway.

The device sends a down-link command with LoRaWAN to send the data periodically.

When the RS485 interface of the R718PC receives the serial port data sent from the RS485 device connected to it, it will actively report the

received data to the gateway in the format of 87+ReceiveData.
