37 Configuring Action Commands Using IEEE 1588 Precision Time Protocol (PTP)
You can implement the IEEE 1588 PTP on Pleora’s video interfaces using any of the following methods:
•
PTP Daemons running on the Windows or Linux operating system
•
Network switch that supports IEEE 1588 PTP
•
All video interfaces connected to one NIC (with multiple ports) that supports IEEE 1588 PTP
•
Multiple video interfaces on a network, with one resolved as the master clock to which the other
devices are synchronized
About IEEE Precision Time Protocol (PTP)
The IEEE Precision Time Protocol (PTP), introduced in the GigE Vision 2.0 standard as an optional
feature, allows you to precisely synchronize distributed clocks with an accuracy of less than one
microsecond on an Ethernet network. In most network configurations, one master clock is used to
synchronize slave clocks.
Using scheduled action commands with the IEEE 1588 PTP ensures that a single GigE Vision 2.0
compliant device (or multiple devices) is configured to trigger an action or actions with sub-millisecond
precision.
To configure the video interface to use IEEE 1588
1. Start eBUS Player and connect to the video interface.
