Can I ask why you are accessing the chassis pins directly? I would definitely not recommend powering any device or sensor using these pins, since there is very little protection on them.

Found out what we needed to know from this article.

Made our own "module" to invert the RS-232 from the chassis through a Max232 IC to drive an LCD. Just tapped 5V (with plenty of protection diodes) from the backplane and ran DB-9's from the chassis to the new module and back to the LCD. Viola!
