Setting Up SMC-Based Devices for Synchronization
Note
The following step is required for any type of
synchronization involving an SMC-based device, including
NI-TClk synchronization. For information about NI-TClk
synchronization, refer to
NI High-Speed Digitizers Help»
Programming»NI-TClk Synchronization Help
.
If you plan to share triggers and/or clocks for the purpose of synchronizing
SMC-based devices (NI 5105/5114/5122/5124/5142/5152/5922), you must
identify or configure certain components in MAX.
(PXI and PXIe Modules)
You must identify the PXI/PXIe system controller
by completing the following steps:
1. In the MAX configuration tree,
a. Right-click
PXI System»Identify As
.
b. Select your controller from the list. For example, select External PC
if you are using a MXI controller in an external PC.
2. Expand the PXI System tree and right-click the name of the chassis you
are using.
(PCI Devices)
You must configure the RTSI cable by completing the
following steps:
1. Connect a RTSI cable between the PCI devices to physically share
triggers and/or clocks.
2. In the MAX configuration tree,
a. Right-click
NI-DAQmx Devices
.
b. Select
Create New NI-DAQmx Device»RTSI Cable
.
c. Right-click the RTSI cable, then select the device to add to the
RTSI cable.
