Avenue 9430 Flexible Matrix Router Installation, Configuration and Operations Guide
GPI Control
The Router 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 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.
