Serial to usb on Kunkin KP184 electronic load

[ntiagobr]

Hello interflexo, i recently bought a new Kunkin KP184, and I'm trying to use your shared Modbus software (Ver. 1.1.05.0 64Bit), however i can't connect.
I bought everything as you suggest in your software manual (Digitus DA-70156 USB 2.0 to Serial (FTDI/FT232RL) ASSMANN), but the Modbus software insists in not connecting.
I wondered if it could be a problem with the cable or the KP184 itself. I connected an oscilloscope, and i can see that there is communication from the handshake, but the Modbus software doesn't connect. I suspect that can be firmware related (2508 ad.002), and has some kind of change compared to previous versions.

I'm leaving this information because i believe we all can benefit from this, if you have availability to adapt your Modbus software for this versions.
I'm 100% available for any further details you may need that i can provide.

Thank you very much in advance for your dedication and support given to this community.
