    Inhibit Mode switch must be in the Manual position. PXI_CLK10 Front Panel Connectors There are two SMA connectors on the front of the PXIe-1086DC chassis for PXI_CLK10. The connectors are labeled IN and OUT. You can use them for supplying the backplane with PXI_CLK10 or routing the backplane’s PXI_CLK10 to another chassis.

  • Page 33: Trigger Configuration In Max

    If static reservations are required, static reservation of trigger lines can be implemented by the user in MAX through the Triggers tab. PXI modules dynamically configured by programs such as NI-DAQmx will not use reserved trigger lines. This prevents the instruments from double-driving the trigger lines, possibly damaging devices in the chassis.

  • Page 34: Pxi Trigger Bus Routing

    Routing tab in MAX. Note Selecting any non-disabled routing automatically reserves the line in all trigger buses being routed to. If you are using NI-DAQmx, it will reserve and route trigger lines for you, so you won’t have to route trigger lines manually.
