1. the maximum number of bus devices connected is 64.
2. the maximum length of a line segment is 350 m, measured along the line between the power supply and the furthest device bus.
3. the maximum distance between two bus devices cannot exceed 700 m.
4. the maximum length of a bus line is 1000 m, keeping into account all segments.
5. It is possible to connect two KNX-20E-640 in parallel in same KNX line without minimum cable length.

Note:
1. Use only ancillary output of KNX-20E-640 to power the KNX device
2. The total current + should be equal or less than 640mA. + ≤640mA
3. The above Bus wiring consideration is still applicable
