Neat... I had figured that was a firmware updating area.
So I clicked System Management >Device Update
Under the Backup Configuration section, there are 3 checkboxes:
Incl Running Status, Incl. Default Value, and Use OBi Version.
I first tried no boxes initially, and I got a 255,074 byte file. Then I tried selecting all 3 checkboxes, and I got a 172,269 byte file. That surprised me. I expected that including three things would make the file larger rather than smaller.
Looking at the files, the one with the checkboxes selected uses shorter notation such as 'P' instead of 'ParameterValueStruct'. So I suspect that one with no boxes checked would be complete.
Mucking with the settings in the OBi202 local web interface directly would probably interfere with the use of OBiTalk. I wonder what the interaction would be. Would ObiTalk have its own cached version of what it thinks is in the box and would overwrite any changes, or would it read the current settings from the box each time I went into OBiTalk? If that was the method, changes made in local web page would not preclude using OBiTalk later.
Reading the Administration Guide impresses me with the power... it has regex-like representations of numbers and such. It is also very challenging, and it would be a comfort to think that I will be able to restore the state if I mess something up.
