How to choose within a series

Choose for your project

Match device-side protocols and the host system first, then check ports, wireless connections and capacity. Candidates below use confirmed model specifications.

You need multiple serial and Ethernet protocols

Check models confirmed to cover all acquisition protocols for serial and Ethernet connections. Check protocol scope and physical port counts separately. Confirm dedicated CAN, KNX TP and 2-wire MBus connections for the specific model.

This guidance narrows the candidates. Confirm communication roles, read/write direction, the point list, wiring and model-specific resources before final selection.

“Unconfirmed” means documentation does not establish a value; it does not mean zero or unsupported.
