Tally (On Air) notification can be enabled for TalkShow’s front panel LCD screen, as well
as being displayed on the Return video stream sent back to the remote Skype™ caller.

Tally notification can be sent from a NewTek TriCaster™ live production system* across
a network connection, as described in Section 3.6.1. Otherwise, it can be triggered by a
GPI signal presented to the Tally connector on TalkShow’s rear panel.

* Requires TriCaster Advanced Edition.

Here is a ‘pin-out’ for TalkShow’s HD15 Tally connector:

Pin7 – GPI 3 Input

Pin8 – GPI 4 Input

Pin9 – GND

Pin10 – GND

Pin11 – GPI 1/Tally Input

Pin12 – Talk Back (GPI 2) Input

Pin14 – 3.3V (with 20 Ohms current limit)

 GPI stands for General Purpose Interface, a long-serving control protocol.

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.

If TalkShow™ is not already running, power it up now. After logging in if necessary, the
TalkShow Desktop is displayed (Figure 12). We’ll limit ourselves here to configuring
input and output, and move on to discuss connecting to Skype™ and handling calls in
Chapter 4, Live Production Walkthrough.
