If you want to assign certain tablets to certain tables, you can use the Tabletop mode on FineDine.
Simply enable it from App Config and register your tables to the system.
After that, you can assign the ablet to a table from the app. Tap 3 times on the FineDine logo and select the table you want to set the tablet to. From that point on, all the orders sent from that tablet will be registered under that table's ticket.
To close a current ticket, go to the Orders tab on the control panel and checkout for that ticket. A new ticket will automatically be created on the tablet for the same table. To change the table a device is assigned to, simply tap 3 times on the FineDine logo and select a new table.
Multiple devices can be assigned to the same table and they will all operate on the same ticket.
