This command configures the primary and backup steering systems for timing.

  • The primary system is the system to which the receiver steers the clock.

  • The backup systems are used whenever the primary system is not present.

Upon start-up, the primary system must be present long enough to steer the clock to be valid once, otherwise, the backup system cannot be used.

This command does not control which systems are used to set the time. Use the SETTIMESOURCE command to control which systems are used to set the time.
