I have a challenging one for any CTI gurus out there. We currently have changed our processor over to a CTI 2500 from a siemens 555 trying to talk to cluster of moores. Here is the path. CTI 2500 to RBC (505 6851a) to SIMATIC 386/ATM (505-ATM) to a Moore ICI (Model 320). The Moores aren't talking to the controller even though with the original siemens 555 everything communicates fine. Any thoughts would greatly be appreciated.
