How are trigger signals wired on cPCI-1553?

On early revisions of cPCI-1553, triggers were routed to both the front and rear connectors. The rear I/O pin definitions routed to assigned signals in some PXI systems, prohibiting trigger use in that environment.

To solve this problem, newer cards route triggers only to the front panel, connector P3.
