What type of connection do I need from my PBX to my PC to pull SMDR records?

We're in the process of getting a new system, but the boss wants call accounting back now...I've found a little free software package (Call Accounting Mate), but I don't know how to connect the PC to the system for SMDR. Is a special card required? If it is a DB-9 to RJ45 (as I suspect it is) which end goes where?
