In the ATLAS Level 2 trigger demonstrator Architecture B, the S-Link will be used to connect the Trigger Supervisor output with the ROI Distributer Input.
First tests, using a RIO-2 and PMC/S-LINK cards will be started mid March 1997. Those tests will use the LynxOS S-LINK library written by the ATLAS "DAQ prototype-1" team.
