In PCI, users have access to all seven RTSI lines (RTSI<0..6>) through the
RTSI cable. For the NI PXI-6052E, RTSI <0..5> connects to PXI
Trigger<0..5>, respectively, through the NI PXI-6052E backplane. In PXI,
RTSI<6> connects to PXI Star Trigger line, allowing the NI PXI-6052E to
receive triggers from any Star Trigger controller plugged into slot 2 of the
chassis. For more information on the Star Trigger, refer to the
PXI
Specification
, Revision 2.0.
