Unlike "older" Deltacast cards that have a fixed number of inputs and outputs (e.g. DELTA-hd-elp-d 60 (6-input, 2-output) or DELTA-hd-elp-d 80 (8-input, 0-output)) and are only 1.5G, there appeared new 3G Deltacast cards – the so-called "versatile", bidirectional cards (e.g. DELTA-3G-elp-d 8c). Such cards are recognized by letter "c" at the end of their names. These versatile cards should be pre-configured in bidirectional mode that allows you to define the desired combination of inputs-outputs. This can be performed via a free Deltacast application – dCARE, which can be downloaded from the official Deltacast website.
