Generally, each RollUp works independently of each other as they all have a built-in player. However, it is possible to link several Rollups together to form a large screen. In this case, the players are connected in series by RJ45 cable. Our equipment should be protected from heat/humidity and connected by an ethernet cable (not supplied) to our system. For the use of external devices, you will need an additional device: video-processor (cameras, laptop, control room, TV decoder, ...) The video processor supports the following signals: vga, dvi, hdmi, coax, usb and bnc. If a TV set-top box is used, it must be tested one week before and the day before our assembly. (Update). It must be located near the videoprocessor or be deported with the appropriate wiring. We will not be held responsible for poor signal quality. We strongly recommend the services of our technician for your event.
