Customer "happened" onto a new in the box ACS 509 with 4 new 18D's. The instructions for set up requires a supplied PC card be inserted before 509 isfirst booted. The only card I have in stock is a Back Up Restore card. can this be used? If not what card do I need to get for this 509 to get it going? The CD manual and instructions plus some hardware came in the new boxes but no PC card.
