Go-X Series Rolling Shutter GigE Vision I/F (Preliminary)

PTP (Precision Time Protocol)
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 unicast UDP datagram.)
•
Destination port number
319 : Sync, Delay Req, Pdelay Req, Pdelay Resp
320 : Announce, Follow Up, Delay Resp, Pdelay Resp, Management, Signaling
•
Items for synchronization
Time synchronization is performed. Frequency tuning is not performed.
•
PTP time data
80 bit (elapsed time in 1 ns, with 00:00:00, January 1 1970 set as the origin)
•
Timestamp (this camera)
64 bit* (PTP synchronization: LSB64bit* of PTP time data)
•
Supported PTP messages
Announce message (receive only), Sync message (receive 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).
•
When PTP synchronization is being performed, the Timestamp Reset
function is disabled.
•
Because GenICam treats the timestamp (64 bit) as a 64 bit signed integer,
63 bit is actually timestamp data without the sign bit.
