The KNX Spacelogic Line Coupler MTN6500-0101

[Hurr]

Hi Everyone,

The space logic KNX Line Coupler MTN6500-0101 blocks application download from ETS to individual devices across the KNX lines specially while downloading from the Main line to the Sub line. Even the earlier versions of this KNX coupler had same issue. We normally use KNX-USB interface MTN6502-0101 for application downloads from ETS5 and always we have to disconnect the KNX coupler to avoid application download failure. It is time consuming to always remove the KNX coupler connections and connect the KNX USB-interface to the sub-line directly to enable smooth application download. Can anyone advise a solution to overcome this difficulty?

Hello Hurr!
Can you please check the following parameter. And if "enabled" please try to disable it.

Hi Thomas!

Disabling the setting worked with one coupler device in the network.

I still need to check the result with multiple couplers in the network. Hopefully it will work as well.

Thanks!

Hi Hurr,

It might sound silly to you, but check that the individual address of all KNX Couplers is set correctly and that the address of the interface it is using is consistent with its position in the topology.
