PCO Error for OPC DA 2.05A

Experts,

I am using PCO 2.203.1109.245 patch 32692, seeking to connect to a local (same server) RSLinx OPC Server with 2.05A specification. 

When I create the source system I get the following error when try to browse or return to the server list after save:  "Connectivity framework error:  External component has thrown an exception." 

I can create an agent with this source system but it errors when starting with a similarly cryptic error:  "Manufacturing Fault: REASON = Invalid server information.  Parameter name: input"

The odd thing is that I can successfully connect to a local IP21 OPC server with 3.00 specification.

What's going on here?  Why can I connect without error to 3.00 but not 2.05A?  How to troubleshoot connectivity to the RSLinx OPC server in this case?

Thanks in advance,

Dave
