The Multiview output offers a variety of optional monitoring layouts that can be selected at any time
in TriCaster’s Live Desktop.
2. Some TriCaster models also provide an additional, assignable video output on a labeled HDMI
connector. Simply connect a suitable external monitor or device to the connector on the backplane.
3. Stream and Network both require only a network connection.
4. Two special outputs are labeled Display (numbered [5] and [6] on 4RU TriCaster’s backplate). These
ports can serve projectors or similar large display systems, though of course they can be used for
other purposes too.
Note: A mismatch of output format and connection type is possible at times. For example, a Graphics player can
display imagery that does not correspond to the current output resolution or is not supported by the selected
connection type. TriCaster will attempt to display the output despite mismatches, but may not always succeed.
SECTION 3.8 TALLY LIGHTS
TriCaster’s Tally Light support allows you to connect external tally lights and similar devices.
These typically provide a red LED for the video input that is currently selected on the
Switcher’s Program row. (Not a TriCaster Mini feature.)
Note: Tally over SDI, as supported by devices from Blackmagic Design, is natively suported, and requires no special
configuration. Please see also: Section 22.9 regrading GPI support to trigger tally (and more); or search among
third party tally solutions listed at http://www.newtek.com/solutions/newtek-developer-network/all-partner-list.

E NGINEERING N OTES
 Pins 1-(4 or 8) are ‘hot’ when the LED should be illuminated.
 Each LED pin 1 (4 or 8) has a 200 ohm current limiting resistor inside TriCaster.
 With no load (open circuit) the LED pins can reach 5V. With a typical LED load, they can be expected to
reach about 3V.
