Lightware HDMI-3D-OPT-TX210RAK User Manual

A short example of how to use the subscription
In the following, an example is presented, how the subscriptions are working and how to
use them. In the example, there are two independent users controlling the device through
two independent connections (‘Connection #1’ and ‘Connection #2’). The events in the
rows occur after each other.
