| NOTICE: A mix of star and multi-drop configuration is only allowed if the star point is at the controller X-BUS port. In this case, all expanders/keypads must be wired in multi-drop configuration without any other star points in the wiring. |
Not allowed wiring with a second star point
| NOTICE: If the mix of star and multi-drop configuration is not properly wired the reduced signal quality may lead to slow reaction time of connected devices (for example, keypad operation) or even loss of communication to devices. If such behavior is observed a wiring in loop OR star configuration is strongly recommended. |
