The hydrogen generators are fitted with an optional remote control feature (USB-RS232), which allows
the user to check the status of the generator from a remote position, and to start/stop the production of
hydrogen.
The contacts used in the remote control are potentially free relay contacts. The contacts can be configured
via software as normally-open or normally-closed (see the Configuration section). The maximum voltage
and current ratings for the contacts are 1A / 48V. The pin configuration of the remote connector is shown
