How to know your devices are connected

If you're having connection issues between your Master and Slave iPads (waiter pads or other points of sale), check the following are correct. You will know that devices are connected if they are all showing under the Server list of the Master, with a green network signal.

Make sure you always sync your orders as soon as you have restored connection between your Master, Slave, and the cloud (the "server" or backend).

Confirm Abacus is open

  1. Look at your Master POS. Abacus must be currently loaded onto the screen.

  2. If your iPad is open on another screen, close that one and re-open Abacus.

    If Abacus POS is ever not open on your Master iPad (e.g. if you're on a webpage or checking email instead), none of your other iPads will be able to connect to it.
