A: It can provide technical support such as preliminary proposal suggestions, system topology diagrams, point lists and drawing coordination for design institutes and engineering integrators.

A: KNX is an international open standard without vendor lock-in, and KNX devices from different brands can interoperate. Adopting a distributed architecture, it ensures that failures of partial devices will not affect the operation of the whole system, and features strong scalability, making it more suitable for large long-term operation projects such as hotels, hospitals, commercial complexes and rail transit. Most 485 systems adopt manufacturer-specific private protocols, which are hard to achieve cross-brand compatibility.

A: A single KNX bus supports up to 64 devices. For large multi-zone projects, KNX IP routers (such as DLI623T-K) can be used to build an IP backbone network and divide multiple bus segments to realize cross-regional networking expansion.
