Hello, 

Im trying to introduce Multiple input/ouput cards into a New ACE workflow using the ITX node. Anyone familiar in how to accomplish this and any documentation on how to implement this workflow. 

For multiple ACE, you would use a Collector Node.  It collects all the inputs before invoking the rest of the flow.

Each input name should be the ITX input card name.

Hope this will help.  More details on multiple Inputs.  Card names are case sensitive.

Thank you Rex, this helps a lot. Appreciate your time and help with this.
