Introduction

R718PC is a Class C type device based on the LoRaWAN open protocol of Netvox and is compatible with the LoRaWAN protocol.
R718PC supports serial port transparent transmission. It can send the read commands to other sensors supporting RS-485 protocol according to the configured period, and the information returned by the other sensors will be directly reported to the gateway. It supports up to 128 bytes of data (depending on the current communication rate).
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.

Data Report

The device will send a version package Report immediately after power on.
The device has no operation before any configuration is done.

The device sends instructions through LORAWAN to configure the data that needs to be sent through RS485, and it reports the data that RS485 receives to the gateway at the same time.
The device sends instructions through LORAWAN to configure the time to periodically send the data.
When RS485 interface of R718PC receives the serial port data from the RS485 device that it is connected to, it will actively report the received data to the gateway in the format of 87+ReceiveData.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://www.netvox.com.cn:8888/page/index to resolve uplink data.

1. After the sending data period is configured as the 30s, the device sends the transparent transmission data configured by CmdID 04 to the external device according to the 30s period.
   After the external device responds, R718PC sends the data returned by the external device to the gateway in the format of 87+ReceiveData.Configure the device Period = the 30s
   Downlink: 03001E
   Device returns:
   8300 (configuration success)
   8301 (configuration failure)

2. Read the device parameter
   Downlink: 04
   Device returns:
   84001E (current device parameters)

After SetPollSensorPeriodReq(CmdID:03) sets the periodical sending time to 30 seconds, R718PC will send the command that is set by SetPollSensorRawCmdReq(CmdID:05) to the connected RS485 device every 30 seconds, and the response content of  RS485 device will be reported in the format of 87(CmdID) + ReceiveData.

Important Maintenance Instruction

Kindly pay attention to the following in order to achieve the best maintenance of the product:

• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in an excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
• Do not store in an excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding.
  Damaged batteries may also explode.

All the above suggestions apply equally to your device, batteries, and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repair.
