1.Introduction
The R831D is a Wireless Relay Switch Control device for Netvox Class C type devices based on the LoRaWAN open protocol and is
compatible with the LoRaWAN protocol.
R831D is designed to control switch devices, mainly for electrical appliances. R831D allows you to connect and control 3 buttons
and 3 dry contacts. The connected buttons and dry contacts will not affect each other. It will report 3 relay status and 3 input status.
LoRa Wireless Technology:
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It can
be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic meter
reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size, low power
consumption, long transmission distance, strong 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.

The device will immediately send a version packet report along with an uplink packet including 3 relay status and 3 input status.
The device sends data in the default configuration before any configuration is done.
Default setting:
MaxTime: Max Interval = 900s
MinTime: Min Interval = 2s
Note:
The device report interval will be programmed based on the default firmware which may vary.
The interval between two reports must be the minimum time.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver
http://www.netvox.com.cn:8888/page/index to resolve uplink data.

7. Maintenance and maintenance
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets wet,
please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy batteries,
and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest
authorized service facility for repair.
