CONNECTOR PINOUTS
OmniBus II NI PXIe User Manual 7-3
7.3 Module-Specific Wiring
The meaning and use of the databus signals on the LFH connector depends on
the protocol and functionality of the associated module. This section provides
channel definitions and connector pinouts for the more common OB2 modules.
Listings for the
16036 Pin give the connector and pin number for the signal when
a Ballard 16036 cable is used. See Section 7.4 for more information on cables.
7.3.1 MIL-STD-1553
Table 7.2 below lists the pin assignments for the MIL-STD-1553 modules. Be sure
to follow the coupling and termination guidelines provided in Appendix A:
Coupling and Termination.
