[Yaesu] RS-232 interface with FT-990 help requested

[Gerben A.Menting]

Who can help me,

>I have to use pin 2 and 3 of the CAT plug but I am not sure to what I have to connect them. 
>My interface is universal and I have a Txd/Rxd + and Txd/Rxd - available so 
>it should be working with almost all radio types. However, what should I 
>use for the FT-990? Next question is, Txd to pin 2 and Rxd to pin 3 or the 
>other way around?

>Once this is connected correctly, how can I check if it works, in case I do 
>not see any interaction between the radio and DX4WIN. I have checked my 
>interface according to the instruction from the person who has build it.
