Complete model meaning

The complete meaning of KS318-A1-AS923-N is:

This is a second-generation IP65 analog input acquisition module in the 800 MHz-and-above RF class. It provides a 4–20 mA analog input, includes a 10800 mAh battery, supports the LoRaWAN AS923 regional standard, and uses the default final version code N.

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

Reference: PTL-D01 ManThink Technology IoT Terminal Application Layer General Protocol V1.5

Note: The 0–10 V and 4–20 mA models use different identifiers; all other fields have the same layout.
