Synchronization Status

Last Modified: August 20, 2020

FlexLogger displays the synchronization status of your system on the toolbar, helping you troubleshoot synchronization issues based on the status of your system.

FlexLogger supports network and PXIe synchronization for compatible devices. For information on synchronization requirements and enabling synchronization in your system, refer to Using Network Synchronization in Your Acquisitions and Using PXIe Synchronization in Your Project. If your system does not require or support synchronization, you can disable this feature by going to File»Preferences and unchecking Enable multi-chassis and network synchronization on the General tab.

The following image shows an example of how the appearance of the SYNC LED changes depending on the synchronization status of your system.

Refer to the following table to determine the synchronization status of your system and to determine how to resolve any synchronization errors.

Table 1. SYNC Status
SYNC Status Meaning Troubleshooting Tips
No SYNC status in toolbar Your system has only one chassis or device. -
Red Not all devices are synchronized. Click SYNC to display which supported devices in your system are synchronized and which do not support synchronization. Synchronization conditions have been met, but errors exist with the device or network setup. Verify that none of the following issues are present in your system:
  • The external switch used in the network configuration is not supported on the IEEE 802.1AS subnet. (Network sync)
  • Devices are connected on the network in more than one subnet. (Network sync)
  • The HDMI cables are connected to the incorrect "In" and "Out" ports. See your chassis manual for more information. (PXIe sync)
  • Your device does not support synchronization.
  • A supported device with configured channels is displayed in the project but is not present in the system.
Grey Synchronization is disabled in Preferences. Go to File»Preferences and ensure that Enable multi-chassis and network synchronization is checked.
Project is not correctly configured for synchronization.
  • Ensure that at least two chassis or devices support synchronization.
  • Ensure you have one or more channels configured in at least two of the synchronization-supported devices. Devices without configured channels are not included.
Green Synchronization is enabled and the device configuration is supported. -
Synchronization is enabled and the device configuration is supported, but unavailable devices have one or more channels configured for synchronization. Verify your hardware configuration has all devices available.
