[Elecraft] SCS Pactor 3 modem with K3

[Johnny Siu]

Hello Group,

I asked this question before in the mail reflector but did not get an answer.

I would like to connect my K3 with the SCS modem PTC-IIusb to operate Airmail.  
Could any of you advise me the correct wiring diagram between K3 and the modem?  
SCS do not make a specifc cable for K3.

Thanks for your help in advance.

 cheers,
