For existing instruments, start with dry-contact, current or voltage outputs. Confirm the signal type first, then channels, power and configuration. **Read article ↗** [Selection guidesTemperature, humidity, DI or 4–20 mA: choose by what you measureFor new monitoring points, choose by temperature, humidity, ](https://www.manthink.cn/en/resources/sensor-interface-selection/) ## Technical articles From existing protocols to a verifiable data path. ![KC25 DIN-rail collector — product image](https://www.manthink.cn/assets/kc25.jpg) Technical articles ### How to connect existing RS-485 instruments to LoRaWAN with EdgeBus 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. **Read article ↗** [Technical articlesHow to connect existing RS-485 instruments to LoRaWAN with EdgeBusConfirm electrical interfaces and protocols, choose the ](https://www.manthink.cn/en/resources/edgebus-retrofit-checklist/) ![KC25 DIN-rail RS-485 collector — product image](https://www.manthink.cn/assets/kc25.jpg) Technical articles ### KC25: connect RS-485 instruments to LoRaWAN Use a DIN-rail collector and EdgeBus to read, parse and wirelessly report data from RS-485 instruments already in your control cabinet.
