Re: RC getting spontaneously disabled

I am assuming you have built the competition port adapter so that you can run and test auto, etc. Have you checked for bad connections there? Cold solder joints exhibit this kind of intermittant failure. There is also the possibility that some rough handling may have broke one or more of the d connectors on either the RC or OI. This damage is not obvious from the top side. In any event, contact IFI today to get some direction as to operation or failure and replacement.

Re: RC getting spontaneously disabled

No, we do not have a competition port.

But I did find this:

I'm wondering it if this will work.

Nothing displayed but you do want to build one of these...

If you have made one and that seems to be the problem, then you may have shorted a pin when you assembled it. One thing I just though of, (but I think it is mentioned above.) have you tried replacing the modem cable with a new and shorter one? Over the years, teams have had trouble with the modem serial cable just going bad. They get run over and stepped on and the cable is damaged internally. Remember, besides running data the cable is also trying to supply power to the radio. BTW, the RC modem does need to be mounted so that the antenna is not against metal or buried deep inside the robot.
