NXB-KNX Operation/Reference Guide
Appendix B: Troubleshooting
Overview
AMX recommends activating debugging mode during diagnostics to display additional error messages. This is
activated with monitor command "DEBUGON".
The following table provides tips for error definition, in case it does not work. This serves a quick error
analysis ON SITE.
Error
Proposed solution / error definition
No controls possible, no feedback
Ensure NXB-KNX is detected in Netlinx Studio online
tree.
No controls possible, no feedback,
according to "Status" the NXB-KNX is
detected
Enter command "List" in debug mode.
• Are all addresses entered?
• Are feedback values displayed?
Try to switch several addresses directly with "SET"
(e.g. light). If it works, there is probably an error in the
AMX program.
If also no access is possible (Is the light still on?), the
reason is probably wrong group addresses.
NXB-KNX does not appear in the NetLinx
Studio OnLine Tree view
Confirm the NXB-KNX is powered on and connected
to your network using an approved PoE cable.
Use a zero-config client, like Internet Explorer's
Bonjour or NetLinx Studio's Zero-Config tab, to
access the NXB-KNX Configuration Manager.
• Check the NXB-KNX IP Settings match your
network configuration.
• Check the NXB-KNX Master Connection settings
match your AMX Master controller configuration.
Confirm the current NXB-KNX connection status by
viewing the NXB-KNX status banner.
• Obtain the NXB-KNX ip address using a zero-config
client.
• Establish a telnet session with the NXB-KNX.
• Enable display of diagnostic messages by typing
'msg on all'.
• The NXB-KNX status banner will refresh every 15
minutes.
• Or, use the 'show log' command to display the
message log.
NXB-KNX date/time is incorrect
Use the NXB-KNX Configuration Manager Clock
Manager to configure the NXB-KNX time/date
settings.
• It is recommended that the NXB-KNX time/date
settings match its AMX Master controller time/date
settings.
• e.g. The NXB-KNX and the AMX Master controller
both use the same NIST server.
NXB-KNX appears in the NetLinx Studio
OnLine Tree view, but no control or
feedback is possible
Confirm the NXB-KNX device number shown in the
NetLinx Studio OnLine Tree view matches your
NetLinx project's NXB-KNX device number definition.
Use the NXB-KNX Configuration Manager Device
Configuration to change the NXB-KNX device
number.
