Since naturally you would have unplugged #12 and #13 to connect the remote sensor, and you're getting signal on both with the probe only connected to 1. Since that goes out when the switch is off, clearly it's still connected when the port with that label is unplugged - thus you have a label mismatch. -wes _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
