External Reference (Genlock)

The Selenio Frame supports redundant primary and secondary genlock modules. These modules are designed for in-field replacement. Each genlock module includes a loop-through BNC and provides DC clamping for the composite video reference. The composite video reference is provided to both resource modules and to all 14 product modules.
