Figure 8-1. PCI E Series Signal Connection Scheme
Refer to the
Timing Signal Routing section of Chapter 7, Digital Routing,
for a description of the signals shown in Figure 8-1.
Note In NI-DAQmx, you can indirectly route timing signals not shown in the above
diagrams to RTSI. For a detailed description of which routes are possible on your device,
in MAX, select Devices and Interfaces, your device, then select the Device Routes tab.
PXI E Series Devices
The RTSI trigger lines connect to other devices through the PXI bus on the
PXI backplane. RTSI <0..5> connect to PXI Trigger <0..5>, respectively.
This signal connection scheme is shown in Figure 8-2. The RTSI Clock is
connected to PXI Trigger 7. In PXI, RTSI 6 connects to the PXI star trigger
line, allowing the device to receive triggers from any star trigger controller
