1.7
Precision Time Protocol (PTP) Support
The Precision Time Protocol (PTP) module adds the ability to provide time
synchronization via Ethernet using the Precision Time Protocol (PTP) and Network
Time Protocol (NTP), and to synchronize with an external IRIG-B source.
The PTP module features BNC ports for TTL IN and TTL OUT. It also includes an LED to
indicate when synchronization has been achieved.
Note
The PTP module can only be installed in slot 5. For more information, refer to
