What happens to data when the connection to the server is down?

If your slot machine is up and running, the monitoring SMIB (slot machine interface board) installed in the slot machine detects events and collects informations from the slot machines. While offline, the SMIB as an autonomouse device with a separate power feed stores and keeps for a certain time all relevant data. As soon as the connection with the server is reestablished, the data batch is transferred to the server.
