HeK Basel

Hey Guys We're building an exhibition at our Museum and need to use two HTC VIVE's pretty much next to eachother. They both have (obviously) their own Computer and their own two Base Stations (1.0). We're currently running into a problem that SteamVR says, there are too many base stations. Does this even work? Can we use two Vives with their own pair of Base Stations next to eachother without a Wall between them? Would it help to connect the designated pair with the included Connection-Cable? There are a lot of different similar questions around the forum, but we couldn't get a clear answer for our problem. Thanks for your help and all the best HeK
