EQL PS6100XV error when join a group

Hi all,

I try to join an existing group with a PS6100XV (FW version 6.0.2)

I put the group Name, the IP address of the group and the membership group password.

But there is an error.

In this group there already have a PS5000XV (FW version 5.0.4)

Do you think that it's a bug with RSW, may I try with the console cable?

Or may I search somewhere else??

Thanks
