 a new connection, then all databases and collections created from that connection will inherit the same setting. See this code example:

 If you want to read from a secondary node, you can pass :read => :secondary to ReplSetConnection#new.

 A random secondary will be chosen to be read from. In a typical multi-process Ruby application, you'll have a good distribution of reads across secondary nodes.

+    @connection = ReplSetConnection.new(['n1.mydb.net:27017'], :refresh_mode => :sync)
 
 If you want to change the default refresh interval of 90 seconds, you can do so like this:
 
-    @connection = ReplSetConnection.new(['n1.mydb.net', 27017], :refresh_mode => :sync,
+    @connection = ReplSetConnection.new(['n1.mydb.net:27017'], :refresh_mode => :sync,
         :refresh_interval => 60)
 
 Do not set this value to anything lower than 30, or you may start to experience performance issues.
 
 You can also disable refresh mode altogether:
 
-    @connection = ReplSetConnection.new(['n1.mydb.net', 27017], :refresh_mode => false)
+    @connection = ReplSetConnection.new(['n1.mydb.net:27017'], :refresh_mode => false)
 
 And you can call `refresh` manually on any replica set connection:
