This page shows how to configure a SignaLink USB unit using an Icom ID-5100, KT-8900, and IC-207 radios. The instructions can easily be adapted for other radios. You will still need to use the instructions that come with the SignaLink to complement.
Once the SignaLink is working, it can be used to run Winlink, APRS, Packet, SSTV, ...
Read and follow the instructions that come with the SignaLink unit carefully. This page skips over some important details.
If your radio requires the “RG45” cable (like the IC ID-5100), you should purchase a SignaLink USB that comes with a different cable (such as the “6PM”) since regular Ethernet patch cords are easy to come by.
Connect the Signalink to the computer in this order:
SPKRjack using the audio cable included.
RADIOjack using a short Ethernet patch cord (RG45).
There should be a green check mark beside the speaker/Microphone (general computer sounds), and a green telephone beside the USB AUDIO CODEC (Default for communication sounds)

CheckSR is a small, standalone, application that consist of a single exe file. When you double click on it, once it’s saved to your desktop, it provides the capability of analyzing your sound card offsets and gives you the corrections in parts per million (ppm)
This offset (in my case -27 PPM and -27 PPM) can be entered in the SoundModem settings (see above).
Without proper instruments this is a bit of a subjective test, but it's better than nothing.
