Terry,
In the touchscreen, you will see these pages.
This is the discovery page, it should show your control to link to. My demo sees all the test systems at ELK. You should only see one. If you do not, confirm the screen is on the network with the control.
Then, click on the system when you see it in the list. It will prompt you to enter the link credentials.
If this is not showing properly, verify that the touch screen is on 0.13.040. If so, then under installer settings, click factory default and reset the screen. This will clear any settings in the AE Application and return you to the selection screen. Note: on first selection of the application it will run some configurations and restart the screen after a couple mins.
Let me know if this gets your system working. I have published the update to the other screen as well.
Thanks,
Mike
