Configuring GPIs

The GPI and Tally Interface has 8 GPIs that provide crosspoint switching. In the example on the
left, if GPI 1 detects a contact closure it will switch Input 12 on your Videohub to Output 1. This
means when you switch the joystick control on your CCU, video going to Input 12 of your
Videohub will be previewed on your monitor.
The crosspoints can be configured in the Videohub Hardware Panel Setup simply by clicking
inside the Input and Output fields on the diagram and typing in the Input or Output number.
The Videohub Control Settings pane offers two ways to preview the output from your Videohub.
Click inside the diagram to change inputs and outputs for GPI
crosspoint switching and Tally.
Latch Video
If you want the output to stay as selected, choose Latch Video. This means you can press the
switch once on your CCU and the input from the selected crosspoint will stay on your monitor
until another crosspoint is selected.
Select Latch Video if you want your preview to hold until another crosspoint is
selected. Choose Momentary Hold Video if you want your preview to revert back
to the previous crosspoint when you release the control switch.
