If necessary, can I easily change the configuration? Yes, it’s simple. With the OTA functionality it’s possible to upload a new configuration to the GSM-PRO2 remotely. If desired it’s also possible to download the configuration via the cloud from the GSM-PRO2. Make the changes on your desk and upload the configuration again via the cloud to the GSM-PRO2 I/O communication module. The up- en download commands can be executed via the CONTA-SUPERVISION IoT portal or SMS.
