public class YamcsParameterLink
extends AbstractLink
implements ParameterDataLink

Yamcs Parameter link - receives parameters from a Yamcs upstream server.

The parameters have to be defined in the local MDB and have the same name like in the remote MDB. This restriction may be lifted in the new versions.
