Do not plug a USB-Serial adapter into the DE9 on the back of your K2!
That connector has both TXD/RXD signals at RS-232 levels AND internal K2
signals for accessories.
You need to fabricate an adapter that will connect ONLY TXD, RXD, and
SIG GND to the USB adapter. The COM port should show up in Device
Mangler when you plug the USB into the computer. No other ports
required. That COM port # goes into the N1MM+ Config->Ports display.

Hi, after about 4 years of dormancy using other radios, I've just about
finished building assembling my K2 (not the 100W version). I have built &
installed all the accessory modules so far except for the Noise Blanker. All
have checked out OK after replacing a "dud" trimmer in the ATU module.
I now want to connect the K2 to N1MM+ on the laptop, presumably using an
FTDI chipset USB/RS232 port connector plugged into the laptop. I have also
downloaded the Virtual Serial Port Emulator program & created a few virtual
COM ports in the same way as I would if using the K3 with N1MM+.
Using MENU/DISPLAY in the K2, I have switched the PORT - ON, but I don't see
anywhere to specify specific ports for connecting to the logging program & I
note that N1MM+ is not in the lists of programs in the KIO2 manual, which
seems somewhat of an oversight to me but I guess it's a historic omission?
I'm sure others have had a similar problem & hope that someone can point me
in the right direction? I had a K2 some years ago & seem to remember using a
Microham MK2 successfully but I hope to find a way of directly connecting
the K2 without using a Microham.
Any help or guidance appreciated
