Master station

In

Examples:

• In a
  protocol. Master status is normally conferred upon a station so that it may transmit a message, but a station need not have a message
  to send to be designated the master station.
• In navigation systems using precise
  time dissemination, the master station is a station that has the clock that is used to synchronize the clocks of subordinate stations.^[1]
• In
  data transfer to one or more slave stations.^[1]
  At a given instant, there can be only one master station on a data link.

In data transmission, a master station can be set to not wait for a reply from a slave station after transmitting each message or transmission block. In this case the station is said to be in "continuous operation".^[2]
