Trimax 2500

Hello

I was looking for a forum that spoke about the trimax 2500 sat meter.
My question is...do you know if the trimax 2500 software will work with windows 10? I have tried repeatedly and have had no success.
I get the message, 'connection failed, no connection to com1'. I do have the unit powered on, and tried all the ports, it is port 3 that I am plugged into, but I think it might have something to do the the converter cable, RS232 to USB, since my computer doesn't have a serial port, I had to use a C2G 02781 DB9 F/F Serial RS232 Mini Gender Changer/Coupler.
And I am not sure if this is the correct way to connect.
I've also loaded different softwares for the rs232 to usb connection, but none help.
Can you let me know your thoughts on this please?

Thanks,

Tommyboy
