Astronics OmniBusII - Accessing PXIe Card Status Information

OMNIBUS II PXIE SPECIFIC FEATURES
The OmniBus II PXIe also extends the protocols’ TriggerDefine function
capabilities by adding transitional trigger parameters. These new parameters
allow the protocol to be triggered on a high, low, rising, or falling state of the
assigned protocol trigger (A-C). To use this feature, pass the respective
parameter found in
Table 5.4 to the pinpolarity argument of the TriggerDefine
function (e.g. BTI1553_BCTriggerDefine).

5.4 PXIe Status
The OmniBus II PXIe provides access to some useful PXIe card status
information. The desired status is selected by passing in one of the parameters
found in Table 5.5 to infotype in BTICard_PXIStatus.
