We have published an updated version of the PMDX-424 Quick Start Guide. This is document revision 0.6. Most of the changes were minor punctuation or re-wording. We did correct the wiring connections for the DC powered version of the PMDX-424, added more detail to the mechanical dimensions drawing, and added the pin-out for the USB header.
You can download the manual from the PMDX-424 page (down near the bottom):
