Enable Multiple Terminal Ordering
In order to enable multiple terminal ordering, you are required
to purchase either iPad Terminal or iPod Terminal license.
Upon purchase, switch on Enable Multiple Terminal Ordering.
As this is the primary device where you store all your stock files and settings, set it as Main POS.
That's all you have to do in the main iPad.
