Configuring channel plug-ins
Map a generic GPI output to an output on a GPI matrix
In a schedule that is in the format defined by the iTX Import Protocol, GPI events may feature
generic GPI outputs "gpi_0", "gpi_1", and so on – up to "gpi_7". To enable iTX to play out such
events, you need to map the generic GPI outputs to outputs on a GPI matrix in the iTX system.
After selecting a playout channel, perform this procedure for each generic GPI output that
appears in imported schedules.
1.
Select a matrix in the GPI Matrix box.
2. Enter the number (between 0 and 7) of a generic GPI output in the GPI box.
For example, enter 3 for the generic GPI output in this schedule entry:
ITEM
clip Football Highlights
gpi_3 1
...
end
3. Select an output on the GPI matrix in the Output box.
4. Click Save.
iTX associates the generic GPI output with the output on the GPI matrix.
Note:
• You may set a duration for a GPI output by selecting Dur and entering a value in the
Duration box.
The Route Event Configuration panel
In the Route Switch Event Configuration panel, you set options for the control of scheduled
routing events.
In an iTX system that has main and back-up playout channels, you need to prevent iTX sending
commands from both channels to switch a router. To do so, you select Shared Device for each
channel. iTX then controls the router through the main channel.
Depending on the properties of a routing system (e.g. network latency), it may be necessary for
iTX to start a routing event a few frames before its scheduled start time. You can set it up to do
this by specifying a number of frames in the Fire Early box; a typical setting is between 0 and 10
frames.
