Description

VI_ATTR_PXI_DSTAR_SET specifies the set of PXIe DStar lines connected to the slot this device is in. Each slot can be connected to a set of DStar lines, and each set has a number. For example, one slot could be connected to the DStar set 2, while the next one could be connected to the DStar set 4. The VI_ATTR_PXI_DSTAR_SET value does not represent individual line numbers; instead, it represents the number of the set itself. A PXIe DStar set consists of the numbered differential pairs PXIe-DSTARA, PXIe-DSTARB, and PXIe-DSTARC routed from the PXIe system timing slot. For example, if VI_ATTR_PXI_DSTAR_SET is 4, the slot the device is in is connected to PXIe-DStarA_4, PXIe-DStarB_4, and PXIe-DStarC_4. A value of –1 means the chassis is unidentified or the slot the device is in does not have a DStar set connected to it.

Also, although a PXIe slot has a DStar connection, the device in that slot may not. In that case, the value of VI_ATTR_PXI_DSTAR_SET still will be the set connected to the slot the device is in.
