Dave,
?
I'd just use the PC browser you got working.? The HC cannot set the Sites.? You need to do that through the Gemini-2 LAN Server Browser Pages.? The one titled "Site/Time".? There exists five saved Sites, the Active Site and the four saved Sites.? You can make a Saved site the Active site or edit a field and the Active definition becomes unique.?
?
This information stores to non-volatile Ram.? If you want to save and restore the definition you must remember to save all your settings with the HC using Menu->System->Store which stores to the SD Card.
?
Esoterically, you can access this file using FTP (File Transfer Protocall) using the Windows File Explorer program and your Ethernet connection.? Also documented within with some searching.
