Last spring at Dayton, I splurged and bought myself a refurbished Peet Bros.
weather instrument, an 'Ultimeter 500'. It has a 6-pin rj-style connector on
the side of the display unit, which according to the manual can be used for
the optional PC data logger.

I eventually found some info on the peet bros. site itself:
http://www.peetbros.com/HTML_Pages/faqs.htm
Data is 2400/8/N/1
Pinout is:
1 - special
2 - +5v
3 - Output
4 - N/C
5 - Ground
6 - Input(U2000only), N/C(U100;U800)
My Ultimeter 500 appears to be an Ultimeter 100 with a built-in inside
temperature sensor.
