5.2.1 Trigger-over-Ethernet

The optional Trigger-over-Ethernet (ToE) feature for 4x 1GigE adds support for the GigE Vision
Action Command on the quad Ethernet interface. It can be used to trigger cameras over Ethernet
in real time. The GigE specification allows sending these messages by a different device, distinct
from the primary application, which normally runs on the main CPU. A sideband interface allows
the Real-Time Communication Controller to introduce packets into the network:
Up to four different Action Commands can be defined by the application.
The PoE state LEDs described previously are also used for Action Commands: each LED is associ-
ated with one of these Action Commands. When an Action Command packet is transmitted, the
respective LED will flash red very shortly. The PoE state will still be shown for each port by the
green LED.
Please note that Action Commands don't belong to any port. All Action Commands are broadcast
on all four ports.
