General Purpose Discrete Inputs/Outputs (GPIO)
3.6
The ACE1553-3U-
4 provides two General Purpose Discrete I/O's (GPIO’s). The GPIO’s can be
used as simple discrete inputs or outputs, for example to generate strobes (i.e. to another AIM
board) or to sample a digital input signal generated by an external system (or AIM board).
PXIe / cPCIe - Connector Pin Assignment
3.7
PXIe introduces the usage of the I/O pins on XJ4 as legacy PXI triggers, Clock, Star and Local
Bus signals. XJ3 carries the cPCIe reserved pins locations for the PCI-Express serial
communication bus.
