K3/Twin setup, CW problem from radio end PC

[oh6xx]

I tried to read through the forum but couldn't find an answer.

I setup K3/Twin last weekend but I faced an issue with local CW at the radio side. I setup PC to control rotators, amplifier and for local FT8 next to radio at the ham shack. Everything else seems to work from the local PC except CW from DXLog (Wintest, N1MM you name it). I am trying to send CW over CAT cable like we normally do with K3 (with K3USB cable). DTR for CW and RTS for PTT. This works perfectly when the RRC box is not connected. But when I connect RS232 cable from K3 to RRC COM2 and K3USB cable from PC to RRC COM1 neither CW nor PTT works.

I do get frequency info to logging software at the radio PC by setting up COM1 mode to Mode-6, CAT to COM2 (Local) and COM2 mode is Logical parallel with COM0.

Is it even possible to send CW over CAT cable or should I setup Microkeyer II or alike to send CW locally when visiting radio site?

Hello Juha,
I have a TS-480SAT setup and, in parallel, a twin TS-590S setup.
I use a Netgear Nighthawk mobile Router with 4G/LTE.
Both RRC-1258 MkII setups work fine with the Firmware 2.95. / Bootloader 1.10. I work CW for most of the time.
I can configure the COM3(Extra) serial port to either serve as a Winkey for CW or for RTTY to key my TRX with FSK.
This is very handy with N1MM+, F1 sends CQ, F2 the report etc. 
For all of you having problems with the setup, please have a look at my screenshots here:

Some screenshots might be useful for your K3 setup as well. I hope this might help you.
You can send me a e-mail to hb9bjl@bluewin.ch .
