Using PXIe Synchronization in Your Project

Automatically synchronize devices between PXIe chassis.

Introduced in FlexLogger 2020 R4

This feature is available only as part of a complete FlexLogger license. Refer to FlexLogger Editions for more information.

Supported PXIe chassis with the optional timing and synchronization upgrade share trigger and clock signals using HDMI cables.

  1. Ensure that your system includes at least two chassis that support PXIe synchronization. Refer to the supported hardware topic for more information.
  2. Ensure that the synchronization-enabled devices in your system are using the following configuration that supports synchronization:
    Line topology—Also known as daisy-chaining or bus topology. The host communicates directly with all chassis and chassis share trigger and clock signals through one bus line.

    You must properly connect to the In and Out ports on the chassis to enable synchronization. Refer to your chassis documentation on ni.com/docs for additional information on synchronization and networking.

  3. Ensure that synchronization is enabled by going to File » Preferences and checking Enable multi-chassis and network synchronization on the General tab.
When the synchronization-supported devices in your system are properly connected and configured, and synchronization is enabled in FlexLogger, the SYNC displays green in the toolbar, indicating that synchronization is working properly. If the SYNC display is not appearing or is not green, refer to Synchronization Status for troubleshooting information.
