DSN configuration is performed by using ODBC Data Source Administrator (Control panel - Administrative Tools - Data Sources (ODBC)). When creating a new DSN, it is necessary to select D2000 V7.00 Real-Time Driver from the list of drivers.
Data source name (DSN)
Name for the data access.
Server name
Name of the workstation with running the D2000 Server or LOCAL for connection to a local D2000 Server.
From D2000 version 23 it is also possible to enter:
- /RD<group_name> (e.g. /RDmygrp) to connect to redundant group <group_name> using UDP multicasts
- /RF<group_name> (e.g. /RFmygrp) to join the redundant group <group_name> by reading the configuration of the multicast group <group_name> from the registry. For more information - see the chapter Configuration and Connection of Client.

...
The following methods are available:
Note: Other authentication methods than D2000 require a dynamic library d2auth.dll (located in the directory D2000.EXE\bin). To make it available to the D2000 ODBC driver it is necessary to copy the dynamic library to the Windows system directory (System32) or to set the Windows environment variable PATH to include also the directory D2000._EXE\bin.

- SharedMemory - communication using shared memory- possible only for the connection to local D2000 Server
- TCP/IP - communication via TCP/IP
- TCP/IP packed - communication via TCP/IP with message compression
