• Pin5 – reserved
• Pin6 – reserved
• Pin7 – GPI3
• Pin8 – GPI4
• Pin9 – GND
• Pin10 – GND
• Pin11 – GPI1
• Pin12 – GPI2
• Pin13 – NC
• Pin14 – 3.3V
(20 Ohms current limit)
• Pin15 – NC
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.
▪ 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 software support for GPI triggers has not been implemented at this time.
▪ To prevent damage to internal components when making 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 your system is not already running, power it up now to reveal the Launch Screen . (If it is already running,
but is in the Live Desktop , you will need to exit, then click the large triangular Back button at left on the Session
Page to return to the Home Page .)
The Launch Screen consists of two similar pages labeled Home and Session . Among other things, the Home
Page is where you choose basic session settings (see Section 5.1 for a discussion of sessions).
T HE H OME P AGE
When no previously created sessions exist, the icon ring dominating the Home Page defaults to New , inviting
you to create a new session.
