The connection type indicates how the Adapter establishes a TCP/IP connection. The role can be as a Client, where the RA connects to the external, or as a Server, where the RA waits for a connection.
Connected as a TCP/IP HL7 Client
As a TCP/IP HL7 client, the Adapter connects to external server (host/port) and establishes a connection (in active mode).
Connected as a TCP/IP HL7 Server
The Adapter waits and listens to a specific port for incoming connection requests from an external client. Once a request is received, the Adapter accepts the request and establishes a connection (in passive mode).
