Harmony Hub and Inteset PC-IRS5 motherboard ir

Been trying to get this motherboard ir device to work with my harmony hub and turn my computer on but I’m not sure if I’m even doing is correctly. I have a harmony hub remote 650, and when I add a device I’m selecting Media Center PC. After that it just says I’m done creating a device and nothing works. I don’t have a speicifc remote from the IRS5 to send an ir signal to my harmony hub or harmony remote so I’m in need of some help. Thanks
