Omron Retail POS Communication

I'm a software developer working for a system integrator company here in Philippines and one of our client requirements is to be able to retrieve data from an Omron PLU server. The server is equipped with TD85 card and now my job is to look for a solution to retreive the POS data back to the database server. I've checked out Omron's site but it doesnt have any technical manuals available. So I tried posting it here.

Any help is greatly appreciated.
