At the least you'll need an ADAT cable. I would also suggest a BNC cable to sync the units.
If you have not already done so, I suggest you read both units' manuals.

Just want to make sure I understand your post...
So you were successful when connecting the second 1818 to your first 1818 via ADAT?
and you could see 16 channels (8 from each) in Studio One?
but if you try to connect both 1818s via USB you have problems because of the USB on windows.
Correct?
Thanks

I used 2, indeed one as ADAT to the other and it worked fine. The mixer nicely shows the additonal ADAT channels from the second box, performance no problem.

The one issue which makes it a hassle is indeed that you have to connect each box to a separate PC. If you connect them to the same PC the sampling goes wild and you get funny digital noise.
My guess is this has to do with the design of the drivers on windows and actually could be remediated if there would be a dummy driver for the box that is in adat mode.

If there is anyone out there from PreSonus who could help? Because using 2 PCs really does not make this practical.

The end model could be then to have 2 boxes on one PC, use Teamviewer to share the Mixer to an Android Tablet (as there is only IOS tablet version) and there we go, we have a 18 channel mixer with remote control.[/quote]
