Re: Problem receiving console output from cRIO

A null-modem cable is a serial cable with the receive and transmit wires crossed. You will not be able to get serial output from the cRIO without it. You can buy an adapter at RadioShack for $10 (way overpriced...). If you happen to have one of the old LEGO Mindstorms IR tower serial cables, those happen to be null-modem cables as well.
