Only Dyness master Battery in Remote console visible

I have 5 Dyness DL5.0 batteries hooked up to my Victron Multiplus II GX, but in VRM under Device List I have only 1 Device, the Master Dyness.

Under Battery details it shows Battery modules: 1 online | 0 offline

What is wrong in my setup?

I tried to contact Dyness, but no Response yet.

Can somebody tell me what the correct dip settings is for all 5 Batteries, please?

The Description in the DL5.0C manual does Not work at all. Now the Master is Seen by the Victron, but the Slaves are not.

I think it sees it as one battery with 5x the capacity. All of the batteries should have DIP switch 3 set ON. It should work at 500kbps

Sorry, only the master should have DIP switch 3 ON. The slaves should all DIP switches OFF.
The charge limit etc is quadrupled on my 4 battery setup

You can see the individual batteries on the Dyness portal if you have the wifi dongle
