The GSR2 device is an IoT gateway conceived for its use within the elevator environment. It features 4G connectivity. Installed inside the lift control cabinet, it interfaces with the lift controller, enabling telemetry of the elevator.

By default, the GSR2 incorporates a global internal SIM, which facilitates immediate deployment in different regions without the need for an external SIM.

The device has two RJ45 communication ports for connecting up to two complementary units, allowing interaction with the lift controller, and a USB communication port. Additionally, it includes a pluggable terminal block for a proprietary communication bus. While the device typically operates using an external power supply (not included), it can also function independently thanks to an internal battery.

Furthermore, it includes a built-in SIP client that enables VoIP calls, both emergency and test, directly to a digital call center. This feature ensures efficient and modern communication without the need for a conventional telephone line.
