A line-level audio input
Telephone interface board
Through the keypad you select the video inputs for transmission
and display. The picture-in-picture window (PIP) on a main monitor
displays what is being transmitted to the far-end site while the main
screen displays the video image from the far-end site.
An optional second monitor (which does not have a PIP) can display
freeze-frame graphics from the near or far-end site. This additional
monitor can also display a full-screen preview of any near-end
video or graphic source. Without the second monitor, the main
monitor can still display graphics.
