Vertex Standard VX-1700 and CAT connection

I got my hands on a Vertex VX-1700 and wanted to control it by a CAT software. I have connected the radio's Tuner connector with a USB to Serial cable (CT-62 cable equivalent) but the radio won't communicate with my PC even though I tried several different CAT programs. The same cable works fine with the original CE77Win software which allows me to program 200 channels and some programable keys on the front, hence I assume that my cable is OK. Does this radio need a mode change to accept the CAT connection or it has some issue with the firmware 1041? Available documents about older firmware versions specify different positions of the DIP switches on the main unit PCB. Any response to this matter is highly appreciated. Thanks.
