Depending on the generation of your W3000 controller (such as the W3000 Large or W3000 Compact), serial communication requires a specific interface card plugged into the motherboard:

A key strength of the W3000 is its protocol-agnostic approach. It is engineered for open communication, supporting multiple industrial standards to ensure integration with virtually any BMS. Beyond Modbus, its capabilities extend to:
