Delta's LED display controller perfectly supports any type of video and data sources for any display configuration. Content from multiple sources can be simultaneously displayed across multiple display units as one large image, separate images, or a combination of both. Diverse controller options provide the right solution to meet your requirements. The LED controller sending unit is the next step after the base sending unit. It is a single space rack mount unit, with two or four CAT 5 outputs, allowing for increased redundancy and security.
