By default, NoTouch OS will look for a host named
tcmgr and try to connect to it. If it finds an instance of NoTouch Center there, it will try to associate.
In other words, all you have to do to make sure new instances of NoTouch OS will connect to NoTouch Center, set up a
tcmgr DNS host name (A record) or DNS alias (CNAME record) to point to your NoTouch Center installation.
If you are unable to do, so there are many other ways how to connect NoTouch OS endpoints and the management software - please see here: Short introduction (NTC)#Connect clients and NoTouch Center
