Why is my Rally System Display Hub or Table Hub not working?

If you are experiencing  an issue with your Rally System related to the Display Hub or Table Hub, follow the steps below to determine whether the issue stems from one of the hubs or the cable connecting them.

Identify the Malfunctioning Hub or Cable

Diagnosing Rally System components utilizing the following steps requires using Logitech Sync, which is used to manage and monitor Logitech hardware. If it is not installed on your room PC running Rally System, you can download Logitech Sync here.

1. Disconnect the CAT6a cable from the two hubs.

2. Connect a laptop to the USB A to USB B cable connected to the Display Hub and power cycle the hub.

3. Open Logitech Sync App from a laptop (not your room PC).

4. Once the Display Hub is recognized, you will see the Rally System devices and status indicator dots: Display Hub, Camera, and Speakers.

   • If they show solid green dots, then they are stable.

5. Disconnect the USB B cable from the Display Hub and move it to the Table Hub USB port, then power cycle the Table hub. 

   • Note: The Table Hub will take longer. Once its LED stops blinking and goes solid, it is ready.

6. In Sync, you should see the Table hub only with a solid green dot.

7. If both Hubs indicate they are stable, then find another CAT6a cable to run between the Table Hub and Display Hub to test. Connect the new cable, power cycle both hubs, and monitor the Sync application.

Rally Hub Connector Cable

If the steps above work and you can see each device in Sync without a red status indicator dot, then the issue was with the ethernet cable connecting the two hubs. Either re-terminate the ends or run a new CAT6a cable. 

Note:The cable used to connect Rally System Table Hub and Display Hub is specifically a CAT6a cable. Using a different type of cable or one that is longer than the advised maximum length, is not advised. For greater detail on Logitech’s CAT6a cable requirements, consult Rally System Cable Types, Length, Extension, and Configuration Information.
