GPI Settings

6.5.1.

Introduction

The GPI is the General Purpose Interface device that can be connected to the EVS video
server. It allows the operator to send commands directly to the EVS server. These
commands need to be reflected in the IPDirector applications.

The GPI keys first need to be configured in the Setup Configuration on the EVS server.
The configuration on the EVS server includes the following settings:

The definition of the application that will manage the GPI keys. In this case, it would
be IPDirector.

The port on which the serial connection between the EVS server and IPDirector is
defined.

The actions assigned to the GPI keys.

The settings which are defined in IPDirector specify the following:

Which signal will trigger which action on which player channel of the EVS server when
a given key is pressed on a GPI device connected to this EVS server. These are the
INPUT GPIs. The actions triggered by the GPI need to be reflected in the IPDirector
user interface. The INPUT GPIs actions are set up in parallel on the EVS server.

Which signal will be transferred by IPDirector via a given GPI key to a third device.
These are the OUTPUT GPIs.

These settings are defined in the Input GPIs and Output GPIs categories available from
the Tools > Settings menu.

XT Server Selection

In both the Input GPIs and Output GPIs Settings window, the Select an XT Server field
displays all the hi-res EVS servers available on all the network groups.

When an EVS server is selected in the field, the GPI parameters of that server are
displayed. This will allow the user to modify these settings for the selected server.

6.5.3.

Use of TTL GPIs

Each EVS video server has 4 Input GPIs, 4 Output GPIs and 4 TTL GPIs which can be
configured either as Input GPIs or as Output GPIs. Depending on the option selected in
the How to Use the TTL GPIs field, 4 or 8 GPIs will be displayed.

In the Input GPIs Settings window, changing the TTL configuration will result in the
following behaviors:

from Input GPIs to Output GPIs: the configuration of the last 4 Input GPIs is cleared.
