Three HD224 controlled by an HS124

Hello, We have a setup of three projectors Optoma connected to three HD224. A touchscreen HS124 is also in the LAN. I'm a newcomer to Brightsign and have some questions about the subject: - Is there any tutorial or preset that explains carefully how to solve this setup? - Can we load the videos to the Brightsigns online (Brs, from now on) directly without paying the susbcription to BRSCloud? - is there any template of this same subject that I can download? - Those videos must be independent but can be sincronized... How to do it?
