Instructions For Use
Network Topology
KS31 is a standard LoRaWAN device, KS31 normal operation requires LoRaWAN network support. You can use the LoRaWAN gateway of ManThink or a third-party LoRaWAN gateway with the support of LoRaWAN NS.
KS31 supports access to standard LoRaWAN networks such as ThinkLink, Chirp stack, and TTN. You can use the ThinkLink configuration model to implement business functions, card view presentation, and other business logic.
The LoRaWAN network topology is as follows:
Working Mode
Periodic Acquisition and Heartbeat
- [x] The KS31 has 4 AI interfaces that perform periodic sampling and transmit data periodically.
- [x] The KS31 allows setting a COV (Change of Value) threshold. When the sampled data from an AI interface exceeds this threshold, it triggers an uplink data packet.
- [x] The protocol format for triggered uploads and periodic heartbeats is the same.
Communication Test
Use a magnet to stick the position of QR code on KS31 to trigger 2s-4S, which can trigger a packet of upstream measurement data.
Join
Use a magnet to stick the position of QR code on KS31 to trigger 6s-8s, which can trigger a packet of join.
Installation
- [x] Use the drill to fix the back plate to the Wall (keep the back plate Arrow Up)
- [x] Hatch the product on the back plate (slide down after aligning the groove on the back of the sensor with the convex part of the back plate)
communication Protocol
According to the Standard
\PTL-D01 门思科技物联网终端应用层通用协议V1.5
Note: 0-10V Interface and 4-20mA interface of the two types of products in the protocol identifier is different
