3.12.4. Configuring Whether the GPI Inputs are Edge or Level Activated
GPI SETUP
This menu configures whether the GPI inputs, that are available for user
functions, will activate on rising or falling edges, or high or low levels.
Individual menus for each GPI input allow each input to be independently
configured. For simplicity, only the
Gpi 1 type
menu will be shown.

3.12.5. Programming the GPI Input Functions
The GPI inputs can be configured to operate in one of four modes using the
Gpi Encoding
menu item. In
three of these modes, many of the GPI inputs have pre-assigned functions, and the unused inputs are
available for the user to program for a specific function. In the fourth mode (when the GPI Encoding is set
to
none
) all 8 GPI inputs are available for the user to program for specific functions.
The
Program Gpi
menu is used to program the functions of the GPI inputs that are available for user
functions. Individual menus for each GPI input allow each input to be independently configured. For
Simplicity, only the
Gpi 1 type
menu will be shown.
GPI SETUP
If the GPI function is already determined by one of the encoding modes, the
front panel will display a message such as
Gpi 1 Encoded.
The
afv
function will cause the selected video and associated audio inputs to
switch to the indicated output busses. The
v1only sel. i/p
function will cause
only the selected input video to switch to the output video buss. The
1a, 1b,
2a
and
2b
functions will cause the selected audio input to switch to the output
audio buss shown in brackets.
When one of these modes are selected the button corresponding to the
selected input will blink. To select another input press the corresponding
button (the input button LED will turn On) and confirm your selection by
pressing the
SELECT
key (the input button LED will blink).
Disable GPI
will turn off the GPI input.
