
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.

GPI stands for General Purpose Interface. Pins 11 and 12 are assigned for possible future use as GPI1 and
GPI2 connections, but support for GPI triggers has not been implemented in TriCaster at this time.

To prevent damage to TriCaster’s components when making external connections to the tally light jacks,
care should be taken that connection to Pins designated GND (Ground) are always at ground potential.
SECTION 3.9
STARTING A SESSION
If TriCaster is not already running, power it up now to reveal the Startup Screen. (If TriCaster is already
running, and is in the Live Desktop or another area of the interface, you may need to click the small [x] button
at upper-right to exit, or click the Back arrow at upper-left in the Session Page to return to the Home Page.)
The Startup Screen consists of two similar pages – Home and Session. Among other things, the Home Page is
where you choose basic TriCaster session settings (see Section 5.1 for a discussion of sessions).
