Re: IFI Operator Interface Power Consumption
Ryan,

Were you measuring that number with the OI on the power supply, radio connected on OI and Robot and generally everything working? I can't imagine even our dinky short range radio modems drawing less than 50 mA when transmitting. And it should be transmitting almost constantly while the robot is running, provided you're talking over radio and not tether. So really, I was expecting at least 200 mA or so while everything's running.

Also, how did you measure the current anyways? I mean... I'd willingly cut and strip one of the power supply leads to discover this, but only because we've got half a dozen now and really need less of them at this point.

EDIT: Per Joe below, my expectations above are that you're measuring on the output (9V) side of the power supply.
