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.1
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 (page29), or Keypad/Display Interface (page25).
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)
Type: Standard RJ-45 8-pin connector, 100 Base-T
Qty: 1
Packet type Ethernet DIX II (RFC 894)
Protocols IPV4, IEEE1588, 802.3, ARP, and PING
