NXB-KNX Operation/Reference Guide
Integrating with NetLinx
The NXB-KNX is a native ICSP device in NetLinx. The NXB-KNX associates each actuator (actor number)
with a corresponding Channel and Level mapping.
For example the value of actor 1 will map to Channel 1 / Level 1, and actor 52 will map to
Channel 52 / Level 52. These Channels and Levels are associated with the NXB-KNX device.
The default number of Channels and Levels supported by the NXB-KNX is
256
.
If additional channels/levels are required to support additional actors the NXB-KNX can be
configured to allocate additional resources.
Refer to “ICSP [ch=n][,lv=m]” on page 26.
For a full listing and description of all supported NetLinx SEND_COMMANDS and String
Feedback, refer to the
NetLinx Send_Commands
section on page 23.
Channels and Levels
All addresses are available as channels.
The current value is mapped to the corresponding channels of the device.
All addresses are available as levels.
For every value change the current value is transmitted as level to the program, for instance to control a
bargraph.
Data Types
The character sets supported by KNX are
ASCII
and
ISO 8859-1
.
