Network Port (“1588”)
A IEEE1588-compliant “ordinary clock” is available from a stand-alone Ethernet port, labelled “1588”, on
the rear panel of the IEEE 1588 card.
PPS Output (“SYNC OUT”)
A raw unfiltered PPS output is available from the stand-alone BNC connector, labelled “SYNC OUT”, on
the rear panel of the IEEE 1588 card.
The PPS Output from the IEEE 1588 card while configured as a PTP master:
•
50% duty-cycle, +/-10% typical
•
Please consult the datasheet online for additional specifications.

Behavior
The IEEE 1588 card can function as:
•
PTP Grandmaster
-
Best Master
-
Preferred Master
•
PTP Slave
-
Primary Reference
-
Secondary Reference
-
Standby
User Interface
All of the IEEE 1588 card’s functions can be managed using the Web Interface (page 31), Command
Line Interface (page 29), or Keypad/Display Interface (page 25).
The following 1588-related functions are available from the command and keypad/display interfaces:
•
F130 - Precision Time Protocol Status (page 116)
•
F131 - Precision Time Protocol Network Config (page 119)
