Trigger width detection
The figure shows the trigger signal negative polarity (detecting Low level width).
PTP (IEEE1588)
When running the unit in GigE Vision 2.0 mode, the unit can expose by synchronizing with a PTP (IEEE1588) server.
This can work as a master or slave of PTP (Precision Time Protocol). Operate as a slave when you have a grand master
device. When a grand master device is not available, you can make a single camera as a master and synchronize between
cameras. You can set the current time on the camera which is treated as a master. If you don’t set the time, the time the
power was turned on would be 1/1/1970 0:00.
To use IEEE1588, you have to launch the camera in GigE Vision Version2.0 mode.
Restart the camera after you complete the settings.
You don’t have to set these parameters in normal conditions.
The device to become the master will be determined automatically by the best master clock algorism.
The camera is available for use when the status is either master or slave.
It takes around 10 sec. to start synchronizing from when the function is enabled.
