Connect Wallet to remote node/wallet

[mightyMight]

Hi there,

i want to establish a connection from a qt wallet to a remote wallet node.
The basic setup:

graphical wallet                       wallet in daemon mode
<client>       -------------->             <server>

I had seen that this is for instance possible with monerod. But i want to set it up for coins like black and block. I know about the commandline args i can give to the wallet like:
rpcuser/ rpcpassword / rpcport / connect. But none of it has worked so far. What commandline args do i have to give to the qt wallet?

Thanks
MM
