Hi Matthias,

I was able to successfully update an EN4, EP4, and RDM10 from this version. However, on the EN4 and EP4, updating the firmware also reset all of the settings. This did not happen with the RDM10.

I also haven’t figured out/don’t see the new Universe Browser feature on my EN4.

System/Display/Home Screen/Universe Browser

Thanks! Is there a way to get back into that once I hit back which takes me to the “normal” home screen without going back into the menu and reactivating that setting?

hit the back arrow until the universe highlight turns off.

After using CLU to update an EP2 to firmware 2.92 it also reset the unit. It took a moment to regain control of the unit as it was plugged into a 10.101.7.x IP range with a sACN DHCP preset. After the update, it went to the 2.x.y.x with an Art-Net preset.

Is it possible, that after the firmware updates it can stay on the preset (or custom configuration) that it was set to prior to the update.

Thanks for the hard work on another great product line.

Is it possible to utilize RDM from the CLU or will that still need to be done from a console?

Any plans for a Mac based version of CLU?

RDM is not available within the app, but it is planned to add this.
We may offer a MAC version once the feature set is more complete.


There’s a “bug” in the CLU.

When you set a port and clone all the other port to it. The cloned port are not displayed as clone in the CLU.

Example :
Set the port 1 to out artnet 201. Set port 2 to clone.
In the CLU you will see port 1 out 201, port 2 out 2 (should be 201).


Does CLU assume that your computer’s NIC is using a network submask of

No, any valid subnet works.

Please note that the power cycle order of turning on the router and EN4 matters. I realized that the reason I couldn’t get the EN4 to show up in Onyx was that I plugged in the power to the EN4 first. It doesn’t appear to refresh its search for a router automatically. So I found that if I navigate to the network settings of the EN4 with the dial/knob and, since I’m using DHCP, hit enter (push in the knob) on that setting already chosen in the EN 4 , it will subsequently get an IP address from the router. After doing that it then shows up in Onyx.

Tried to use the NCU Release Candidate to update an EP4 to 2.9.2, however, all it does is identify the device. I can’t select any status or configuration options on the device with NCU. These options do work from the web interface.

The device has a red world icon. What does that indicate? This device has the invalid DHCP IP address reported in this thread

Given that NCU isn’t working, is the web interface the only route to update the firmware? Or would you suggestion something else like a factory reset first?

After switching to a static IP address, NCU was able to update the firmware to 2.9.2. After the update, the device defaulted back to a 2.x.x.x. address and all settings/configuration was erased.
