I'm trying to get a K3S talking with N1MM Logger+ for the first time. The K3S config RS232 is set to "USB", I plugged in the USB cable and see that Windows has assigned it COM5, I configured the Port in N1MM Logger+ to K3 38400 N 8 1 Off Off and I get "not responding." Is there a trick I'm missing? Thanks & 73, Barry N1EU
