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 3.9 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.
