Explained: Difference between one, two or five RS-485 buses on the UNii

We’re happy to explain

That the UNii can be expanded with a single RS-485 bus expansion board is well known by now, but the new 4-bus expansion board is less well known.
This expansion board can be placed in the control center, making five RS-485 buses available.
Very convenient and specially designed for taking over other systems from brands such as Honeywell, Aritech and many more.

The takeover and conversion of such a system is even faster and easier with an UNii in that case!
In most cases, all bus cabling can remain intact and be connected directly to the five UNii RS-485 bus connections.
