Depending on the source the input of the GSM-PRO2 can operate in digital or analogue mode. This gives maximum flexibility during the development process. In case of a change in signal type, an input can be easily changed from digital to analogue mode or vice versa. Give each input a clear name for easy recognition. This will be shown in all applications. For each individual input contact(s) created, you can select whomever to receive a message via per SMS, e-mail or by a phone call. In the CONTA-SUPERVISION IoT portal and App, a message will be displayed shortly and will be moved to the event list.
