GPI Out

GPI is designed to allow the user to trigger playback of an external playback device such as
Datavideo's HDR-80/90. GPI OUT allows the user to configure your GPI connection.
First enable the GPI port and then set the GPI mode, which is either level or pulse. The pulse
width can be configured in Width sub-option (1-9).
Once the GPI function is enabled, you can assign it to one of Inputs 1-8 which can later be
used to trigger external devices and the delay can be set to a value between 0 and 99.
