[wxsig] Problem Resolved -- Thanks

[Steve Allen]

Thanks for the input.

The "problem" was really a very simple one, and is due to the
interface that I was using -- the DS 9097U which is a serial
1-wire interface.  It is assuming that the devices are all powered
by the 1-wire bus - and the temperature monitor on the board is
powered by the bus, so it worked.  There are only two wires coming out
of this interface -- i.e. "true" 1-wire interface.

However, the humidity sensor and Battery monitor expect to see
5V  -- through the extra pins on the connector.  I hooked up a 5V supply
to the pins  (P2 and ground) and the humidity circuit worked fine.  This 
explains
the confusion I had when performing the test under the AAG section of the
instructions - i.e. no 5V.

So -- for anyone using the direct computer interface like the
DS9097U instead of the T238+ or inside weather board, they
need to supply 5V to the two extra pins on the cable. This does get swapped 
when
you go through the AAG Weather station, so have to be
careful here.

I found a "power injector" from "hobby boards" that interfaces
either a 5V or 15V power supply to the bus -- with RJ-45 connectors.
They also have adapter cables to go from RJ-45 to RJ-11 if you need to.

Thanks a lot for the help.
