Network address

The network address is composed of the area, line, and device address (even if no
area and line couplers are used).
Example: 3.7.21 (Area 3, line 7, device 21).
The address reflects the unambiguous position of a device on the overall network
and is UNIQUE.
The RXB / RXL controller are factory set to address 0.2.255.
The following ranges are available:
Area: 0 ... 15
Line: 1 ... 15
Device: 1 ... 253

Limits

Communications on the Konnex bus takes place at 9600 Bit/sec. We recommend
limiting one line to no more than 45 controllers to keep bus traffic within reason.
More lines should be setup and separated by a line coupler when there are more
controllers in a plant.

Zones and zone addresses

In LTE mode (together with Synco devices), set up various zones. We recommend
using worksheets for engineering.
