PTP (Precision Time Protocol)
Related Setting Items:
The camera can work as the slave for Precision Time Protocol defined in IEEE 1588. When the
IEEE 1588 master clock exists in the network where the camera is connected, this function
synchronizes the camera to the time of the master clock.
Transport to be used: Multicast UDP datagram (224.0.1.129); however, Delay Resp is a
l
unicast UDP datagram.
Destination port number:
l
319 : Sync, Delay Req, Pdelay Req, Pdelay Resp
l
320 : Announce, Follow Up, Delay Resp, Pdelay Resp, Management, Signaling
l
Items for synchronization: Time synchronization is performed. Frequency tuning is not
l
performed.
PTP time data: 80 bit (elapsed time in 1 ns, with 00:00:00, January 1 1970 set as the origin)
l
Timestamp (this camera): 64 bit* (PTP synchronization: LSB64bit* of PTP time data)
l
Supported PTP messages: Announce message (receive only), Sync message (receive
l
only), Follow Up message (receive only), Delay Req message (send only), Delay Resp
message (receive only)
Cautions:
The Timestamp Tick Frequency register value is fixed at 1,000,000,000 (1 GHz).
l
When PTP synchronization is being performed, the Timestamp Reset function is
l
disabled.
Because GenICam treats the timestamp (64 bit) as a 64 bit signed integer, 63 bit is
l
actually timestamp data without the sign bit.
How To Configure
1. Set GevIEEE1588 (TransportLayerControl) to True.
2. After several statuses from Disable, when a Sync Message is received from the PTP server,
Slave is Displayed in GevIEEE1588 Status.
