Orbcomm ST2100
The ORBCOMM ST 2100 is a compact, rugged satellite IoT terminal designed to connect external controllers, gateways and industrial equipment beyond terrestrial coverage. It provides two way messaging over ORBCOMM OGx or IsatData Pro, with integrated GNSS, low power operation and a simple RS-232 AT command interface.
Its sealed IP67 enclosure and flexible mounting options suit both mobile and fixed assets, including commercial vehicles, railcars, heavy equipment, pipelines, pumps and tanks. Unlike the programmable ST 6100, the ST 2100 is designed for straightforward integration with an external host controller.
Key Capabilities
Compact two way satellite connectivity for integrating remote vehicles, equipment and industrial assets with an external controller.
Two way connectivity over ORBCOMM OGx or IsatData Pro
Up to 1 MB messages in each direction using OGx
Simple RS-232 AT command interface for host integration
Integrated GPS, GLONASS, BeiDou and Galileo positioning
Rugged IP67 enclosure with side or bottom cable access
Simple Integration for Remote Monitoring
The ST 2100 connects to an external PLC, gateway or general-purpose controller through a single RS-232 interface and intuitive AT command set. This simplified, non-programmable architecture makes it a practical option where the host system already handles application logic and only requires dependable two way satellite messaging.
Integrated GNSS provides position and timing data, while event notification, one-pulse-per-second and reset lines support closer integration with connected equipment. Side- and bottom-cable mounting options also make the terminal easier to accommodate within vehicle, machinery and fixed industrial installations.
