How do I get Logic to sync to external audio device?

Question

Here is what I am trying to do:
I have a Big Ben which I want to use to sync everything together. I have Lynx Aurora converters on the way but for now I need to use a 002 rack with a Presonus DigiMax for audio i/o. So basically, I want to connect BIg Ben to 002 with SPDIF cable and to Digimax with Wordclock cable and that all seems to work fine when Logic is off. However I can't get Logic 8 to sync to the Big Ben through the 002 which is used for ins and outs. I can get everything synced by setting Logic to Internal sync and then sending SPDIF from 002 to Big Ben (which syncs externaly to that) and then connecting wordclock out of Big Ben to Digimax. There has got to be a better way.
I have tried setting Logic to external sync ( not exactly sure which method to use since nothing in the manual says that a particular setting is to be used with the i/o except maybe External or Free in Core Audio under Audio Tab on Sync settings - anyway this didn't work). I can use Digidesign CoreAudio Manager to set 002 to SPDIF but whatever I do, Logic doesn't not reflect changes to the clock rate. I someone could guide me on getting Logic to respond to Clock changes from 002R, I can probably get it going from there.
Thanks,

This is what I have figured out so far. If I turn off Logic, the 002 and Digimax clock just fine from the Big Ben. When clocking Logic from an external audio source (by using external or free under the audio tab of Sync preferences), that when I change timing of Big Ben, the audio changes to indicate it is receiving word clock. Logic throws up errors saying that there is a mismatch from external sync to project settings or some such error message. I can then change the clock in Logic to match what the Big Ben reads and errors go away and things indicate that it is clocked correctly. This seems to work, I am just used to other programs that when I change the clock setting on the Big Ben that they reflect those changes right away.
And yes I can synch the 002 to the Digimaz but it still doesn't work correctly until I manually change the clock setting in Logic as well. I just wonder if this is how things are supposed to work in Logic or if I am doing something wrong? The 002 is just a temporary solution to get me through a session tomorrow. After then I will have a Lynx Aurora 16 connected with the Firewire option and then use the Lynx AES16 PCIe when it is available in a few week (or hopefully not months). I am just trying to get a handle on how Logic syncs to an external converter. And while Syncing and wordclock are maybe not the same thing, under the sync menu is the only spot where I have found wordclock even mentioned (at least it is in the manual when describing what some of the options allow).
