It is extremely important to know that Cattura Video has deprecated the use of the Datapath cards do to unforeseen circumstances. We are not currently supporting the Datapath development. Most units shipped since 2013 will have Blackmagic If you have a unit with a Datapath card please contact Cattura Video's support at firstname.lastname@example.org
The below page will help you understand what kind Blackmagic card you currently have as well as the types of connections that are possible with said cards.
Below is a chart that will help you to determine the connections possible natively, w/ adapters and converters.
* 2 converters is VGA to HDMI then HDMI to SDI
* Also note that the Quad does allow for 4 sources but at this time in our development we can only capture 3 sources @ 720p otherwise try 4 SD
