Good afternoon,
I'm trying to connect the smart motor SM34165D to pc using RS-232 interface with the smart engine software(SMI). By activating the option "detect usb motors" or "detect motors on rs-232 chain" SMI software does not detect motor and I dont know why it´s happen. The 7W2 Combo D-sub connector cable is cut at one end (was already cut when I received the engine ...) connecting wires A1 and A2 to my source 27vdc - 37A and connecting wires 3,4,5 7W2 Combo D-sub connector rs232 female connector respectively 2,3,5 goo.gl/FDHQft.
I do not have problems of power supply because it is new and the green LED motor blinks when I turn the engine source.

Have tried using rs-232 connector to usb goo.gl/Swk6vm, but the results were the same.

I've been reading the user guide goo.gl/xr4qQe smart engine but without success: (

Any help would be very useful. Good weekend.
