we are planning to install a 2-channel video-presentation that is synchronized with LED-stripes. Basic configuration: both videos start in sync, and at the end the LED-stripes light up for one minute before the next loop starts. A BrightAuthor presentation would do the sync job and send the commands to the LED power supplies.
What would be the best / easiest way to sync the players to the LEDs?
GPIO: as far as I understood we would need an interface (http://www.hms-electronics.com/BrightSign/data_sheets/bs_hd_4x4.htm) and a relais (cannot use BS-4X4R-REV2 since we need 230V, would not want to use Relay-2 since it has no safety approval).
Any suggestions for relais that would work? Am a little scared to run 230V to the relais and from the relais to a multisocket for 8 power supplies for the LED-stripes. Maybe there is a relais with plugs and sockets?
UDP: connect the players to a network switch and connect an UDP relais to the switch like this one: https://www.kmtronic.com/LAN-Relay-Controllers?product_id=63. Same problem: running 230V to and from the relais. Maybe a stand-alone relais like this one might work https://www.anel-elektronik.de/OnlineShop/main_bigware_34.php?bigPfad=22&items_id=33 ???
Do these ideas make sense, and which setup would you prefer? Do GPIO and UDP differ in usability, reliability etc.?
Any help would highly be appreciated!
