GPIO Settings
The
GPIO Settings
web page shows an overview of connections between
logical inputs and logical outputs, this web page allows the device to be
configured to perform actions when events occur.
The inputs can be of type:
• Physical GPI
• Virtual GPI
• Cough GPI
• Events
• User buttons
The outputs can be of type:
• Physical GPO
• Virtual GPO
• Events
• User LEDs
• Relays
An example scenario of when these logical connections might be useful is
as follows:
In a particular setup there is an LED sign which can be controlled using a
physical GPIO connection, the commentator wants this LED sign to be
turned on whenever they are on-air, therefore they add the event
On Air 1
as an input, then they add a physical GPIO as an output selecting
Physical
Port 1
. They then click in the white square which is in line with both that
input and that output which causes a connection between the two, to be
made. Now whenever the first commentator is on-air their corresponding
on-air LED sign will illuminate.

In the example commentator position 1 is on-air indicated by the green
lightbulb on the input
On Air 1
the routing to
Physical Port 1
becomes
active indicated by the green box between them. The lightbulb on the input
Physical Port 4
is also green which indicates that this physical port is active,
in the case it activates the output
Cough 2
.
