003 and Elevenrack in Pro tools 11

I want to know if it is possible to use the digi003 and Elevenrack at the same time in PT11? I just want to use the 003 as the main hardware and hook up the Elevenrack via SPDIF to record guitars. The hardware setup only shows one hardware at a time even though they are both hooked up via firewire and USB. I'm pretty new to PT11 and can't figure out how to use multiple hardware. I also need to learn how to embed the Elevenrack for audio tracks. I am using Mac OS 10.9.3 .Any help would be greatly appreciated. Thanks!
