Hello Cesar,
Good day. Thank you for your clarification.
Yes, this is possible but as per the following scenario:
1. Device authorizes RFID/iButton (I/O parameter, On Change & High Priority)
2. Server receives an event with RFID/iButton and send commands to enable RS232/RS485 settings
3. RS232/RS485 data is sent to the server.
But if you are talking about GPS and I/O Data then you will need to enable the Min Period and Send Period parameters in Data Acquisition.
Please try this and let me know if it helps.
Kind regards.
