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 or GPS
network.
The PTP module features BNC ports for AM OUT, TTL IN/OUT and GPS IN. It also
includes an LED to indicate when synchronization has been achieved.
Note
The PTP module can only be installed in slot 6. For more information, refer to
