Flexible I/O

The modular rear panel allows custom I/O connections per card (included with individual cards).


The optional redundant power supply provides a secondary power source in the event of a primary power failure.

Ethernet Access

A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.

DashBoard Software

DashBoard software offers quick and convenient configuration and control of openGear cards on macOS, Windows, and Linux.
