That rig has VOX so if you want to keep things simple forget about using PTT.

3) Put the mic near your rig's speaker with the rig tuned to the data mode sub-band of your choice.
4) Bring up Digipan and you should see some decode of the signals coming over the speaker if you have things set right.
5) Make a cable to go from your sound card speaker/output jack to your rig's mic audio input (you may only need a couple of wires to do this.
6) Try transmitting (into a dummy load) using Digipan and adjusting your VOX settings.
With the above no need to mess around with USB or serial interfaces, etc. Some ops never use their PTT for digi-modes, the VOX works great and it comes pre-isolated! Obviously using the mic subjects the input to background noise, but for starting out it will work fine. Alternatively, you could just put a jumper from your rig's headphone jack to the sound card.
