You will need the GSA-55 to connect the gauge to the simulator.


The technology behind our products is based on a BUS system.

Basicaly, the inflight data is extracted from Flight Simulator through FSUIPC (or directly from other simulators) and processed by our software. During that process, the data is cross-referenced with the gauges/modules that have been configured in the simulator setup.

Hence, the GSA-software extracts the relevant flight information for those gauges and links them to the gauge ID, then sends them through the data chain and drops at each gauge/module the relevant data.

That information is the processed by the gauge itself to calculate the needle position, direction and speed to simulate the movement of the needle (or frequency reading/writing for radio modules)

All this happens up to 30 times per second (parameter can be assigned)

The data is transported from the interface (GSA-55) to each gauge connected in a daisy chain configuration. We use a flat cable with 10 wires and the appropriate female connectors.
