### [KC25: connect RS-485 instruments to LoRaWAN](https://www.manthink.cn/en/resources/kc25-rs485-lorawan-retrofit/)

Use a DIN-rail collector and EdgeBus to read, parse and wirelessly report data from RS-485 instruments already in your control cabinet. Adapted from the KC25x product article on ManThink’s previous website.

### [KS52: temperature, humidity and leak monitoring in one view](https://www.manthink.cn/en/resources/ks52-environment-water-leak-monitoring/)

Equipment rooms, warehouses and electrical rooms need both environmental data and timely leak detection. This article draws on ManThink’s previous website to explain KS52 configurations and platform integration.

### [Keep existing heat meters: build a wireless reading link with KC22](https://www.manthink.cn/en/resources/kc22-heat-meter-retrofit/)

M-Bus heat meters connect through KC22 collectors, LoRaWAN gateways and ThinkLink for remote meter reading. Adapted from the previous smart-heating article, with a focus on device roles and checks before retrofitting.

### [Choosing a LoRaWAN gateway starts with platform location](https://www.manthink.cn/en/resources/gateway-deployment-selection/)

If you already have cloud or server infrastructure, start with GD6. For a platform running locally on the gateway, consider GD7 with ThinkLink built in. Then check the model against the environment, power, backhaul and regional band.

### [Temperature, humidity, DI or 4–20 mA: choose by what you measure](https://www.manthink.cn/en/resources/sensor-interface-selection/)

For new monitoring points, choose by temperature, humidity, leaks or air quality. For existing instruments, start with dry-contact, current or voltage outputs. Confirm the signal type first, then channels, power and configuration.

### [How to connect existing RS-485 instruments to LoRaWAN with EdgeBus](https://www.manthink.cn/en/resources/edgebus-retrofit-checklist/)

Confirm electrical interfaces and protocols, choose the right collector, then implement reading and processing with EdgeBus / JS. Matching interfaces do not mean matching protocols; existing adapters still need verification for the specific device configuration.
