Setup required means that your cash register has lost all of it's programming, the first thing you need to do is get a default program in it so you can begin programming. Until this is done you will not be able to communicate with it.
Even though you have a stroke keyboard the principle is the same, if you give this a try:
Turn the power off by the plug
Turn the key to the SP position
Hold down the 3 keys marked in green on the diagram above
Keep holding whilst turning the power back on, hopefully it should beep 3 times and kick back into life.
Let me know how you get on.
