There have been reports and testing of the DS2760 thrmocouples:
http://article.gmane.org/gmane.comp.file-systems.owfs.devel/2180
http://article.gmane.org/gmane.comp.file-systems.owfs.devel/93
The datasheet for the AAG thermocouple at
http://www.aagelectronica.com/pdf%20docs/Thermocouple(TAI8560).pdf
Looks pretty close to the circuit shown in
http://www.owfs.org/index.php?page=thermocouples
So the questions are:
1. Do the prior tested designs still work?
2. Is the AAG model different. (There is example code to compare in Delphi
and Java).
When you use the devices, do you see the normal DS2760 values? Temperature,
vis, etc?That would be helpful is tracking this down.

Has anyone had any experience with the DS2760 based 1-wire AAG
thermocouple device?
I have 4 of them and can get none to work with owfs - ie. they all give
"Error: Invalid argument" errors on all outputs
yet they all work with ddeview. The rest of my network works well with
owfs.
thanks

If by path you mean something like "/10.23AD234523/temperature" the answer
is simple:
You use "get" for the root path ("/" or actually just "") and build from
there.
The explanations for what devices support what properties, their format,
function, measurement units, etc is in the man files. That is
domain-specific information that the user must know indep[endently (though
we'endeavored to make function pretty transparent, and must data is returned
as straight ascii characters.)
