This module uses the latest intelligent control software developed from the RollPod technology from Grass Valley. This will allow the GPI to become a central controller for the most demanding network configuration. GPIs can be assigned to RollCall commands as before, but now with the aid of a PC program (RollPod Designer) the GPI can literally interact with the RollCall network environment, unleashing complex interactivity between external devices and/or other Grass Valley products.
