They do not, however, provide a pullup voltage for digital inputs. The first indication of a problem here is the failure of the robot signal light.
Hm, interesting. This may be it, because when I powered it off a bench supply, the swing was 0 to 10v, and went to the .4-.7 swing once we had wired it to the 'bot. I'll have to go poke around with a tester tomorrow. Thanks!
