Hello,

I remember I changed something on this page, but I’m not sure what …

But by default, there is something that should be different.

If you try with the exact value as on the screen shot, hopefully it will work.

Hoping this few input will be valuable and helpfull.

Regards

Guillaume

Hello,

Have you been able to try out ?

Is it working?

If you need further help, don’t hesitate

No luck, set Lumagen back to defaults and reset it for serial but still no go, il keep trying, cheers

Hello,

Is the Lumagen turned on? It must be

And also on the Lumagen ensure the following set up is correct on the RS232 set up page:

Echo: On

Delimiters: On

Report mode changes: Fullv4 (ensure you’re selecting Full v4).

Hope it helps

Hello,

Have you made progress with your Lumagen ?

Guillaume

7

actually what cable are you using ?

8

RS232 cable from Lumagen processor to Global caché.

Ethernet cat 6 cable from Global caché to router.

theres a few cables, null cable and straight , i have a null ( which i think is the wrong one )crossover cable. i think i need a straight cable? thanks

10

Oh yes, now that you talk about it, I remember about this.

Unless I’m mistaken, I have a null cable.

I will check and confirm.

11

I can confirm that I use a null RS232 cable.

The precise model is Dtech DT-9006C and with that cable, it works fine.

I’m having a similar problem and what would be great to have is the exact sequence of steps and screen shots. Are these steps correct?:

  1. Install Global Caché IP2SL as an Integration.
  2. Install Lumagen Radiance Pro from the github johncarey70/uc-integration-lumagen page (v1.0.6 as of this post)
  3. Run the integration from the Unfolded Circle web configurator for installation

I’m oversimplifying, but these steps do not work for me. I continue to get an error message–> Driver not connected. Failed to connect to host: Connection refused (os error 111).

The configurator is trying to use port 4999. Do I need to do an update somewhere to make that work?

Update: After a careful walkthrough with ChatGPT guiding me through the steps, I finally got it working. If everything isn’t done in sequence (including a reset of the Global Caché by unplugging it and plugging it back in), error messages persist.

14

New question: How do you get the Lumagen to switch inputs? I’ve tried INPUT followed by the input number as well as INPUT SOURCE (HDMI1, HDMI2, etc.) and I can’t get either to work.

15

You just use the number, same as the native Lumagen remote

For anyone else that has problems, having set this up previously, and then removing it, I hadn’t been able to get it installed again due to the “Driver not connected. Failed to connect to host: Connection refused (os error 111)”. Here is what eventually worked for me. BTW I am using a GC-100 Global Cache device.

  1. Ensure the GC device is configured on the network with a static IP. You should be able to access the configuration page via the assigned IP
  2. Make sure the Serial Port used by the Lumagen is set as below

  4. You can verify from a Windows desktop/laptop via telnet, using an elevated Command Prompt
  5. telnet 192.168.1.102 4998 will verify connection to the Global Cache device, if you reach a Telnet cursor prompt
  6. telnet 192.168.1.102 4999 will verify connection to the serial port on the Global Cache device, if you reach a Telnet cursor prompt
  7. Here, if you type ZQP and <ENTER/CR> the Lumagen will return a !P if responding
  8. Next Install the built-in GlobalCache Integration on the Remote3, let it auto-detect and find your GC device, and complete configuration but DO NOT add any Entities at the end.
  9. Next install the Lumagen Integration downloaded from GitHub - johncarey70/uc-integration-lumagen, appreciation again for the author who produced this.
  10. On a whim, I decided to reboot/refresh the GC device at this point, as alluded to by another participant on this thread, may be a red herring, but I did it anyway.
  11. When you run the Setup, choose MANUAL. It will default to the correct Port:4999 but ask you for the IP address of your GC device.
  12. Hopefully setup will now complete successfully, and the Entities provided can be enabled for successfully controlling your Lumagen.
