BrightEye NXT 450 Clean Streaming Router
Installation, Configuration and Operations Guide
GPI Control
The Router and Action Control Panel is equipped with 8 GPI (General Purpose Interface) inputs. These
provide a simple, wire-per-function interface for applications such as:
•
Master Control Fault “Panic” Button
•
Monitor Follow in Camera Shading
•
Crosspoint selection from relay contact closure
Connection to the GPI Inputs is made through the female 9-pin D-Sub connector on the rear of the
Router and Action Control Panel.
The pinout of this connector is organized as follows:
Pin #
Function
1 - 8
GPI Inputs 1 through 8
9
Ground
A GPI function is activated by making a momentary connection between the GPI pin and ground. This
can be done with a switch, a relay, or an open-collector driver. The GPI input is internally pulled high,
the external control must sink 1 mA.
Functions are assigned to the GPIs through the Control Profile that has been assigned to the panel.
For more information about Profiles, see Creating and Editing Profiles on page 59.
