The Saleae logic analyzers are data recorders only. They do not support outputting or transmitting signals or acting as "bus adapters."
The Saleae products can record and decode communication between existing components, but it can't transmit. If you are looking for this feature, we would suggest looking at products from TotalPhase, which makes a number of bus adapters capable of this operation.
Without output mode, the Saleae products are not capable of outputting previously recorded signals. Unfortunately, we do not have a good recommendation if you need to do this, but our many export options should make it easy to get captured wave forms out of our software and into another application.
