Use GAM to set a 3-digit gamma level interpolated between a base curve (2.2 by default, or an
arbitrary gamma curve, selected via the BGM Base Gamma control), a high curve (3.0), and a
linear curve. Range is 100-280 (=1.8-2.0).

Use GIO to configure and control the General Purpose Input and Output (GPIO) bits. There are
7 GIO pins available on the 9pin DIN GPIO connector, plus power and ground.

general Message format:
(GIO?)
(GIO? C#)
(GIO C# <Input/Output>)
(GIO C# "List of configurations")
<"IOxO"> (GIO # <state>)
GIO # "List of states")
(GIO # P <Duration in ms>)
Where
C = configure
# = desired pin number or start pin number
x = no change
noTes:
When a command is issued to a pin configured as an input, the command triggers the same
1.
functions as if the input pin actually changed state.
The GIO configuration and state take time to save to the projector. Leave your projector

running for several after your setup is complete.

GPIO numbers start from 1 not zero.
