[Elecraft] K3 Configuration for the SignaLinkUSB" interface for PSK31

[TA2AH]

Hi,
Does anyone have Tigertronics "SignaLink USB" interface uses with K3?
I need help to configure my K3 (Serial # 1230) to use with my "SignaLink USB" interface for mainly PSK31.  
I am using the new SignaLink radio cable to connect it to my K3, which connects to the K3's rear panel Line In, Line Out, and PTT jacks.
Any help would be appreciated.
