# Master & Slave POS Setup

> Running more than one POS device in the same location

## Why use multiple POS devices

If your location has more than one cashier station or a mobile POS for tableside ordering, DuitPOS supports connecting multiple devices so they all share the same tables, orders, and kitchen tickets in real time.

## Setting up the Master device

The **Master** device hosts the connection that other devices connect to — usually your main counter POS.

1. During setup, select **Master POS**.
2. Go to **Settings → Connection & Terminals** to find your device's connection details (a local network address and QR code, if supported).
3. Make sure this device stays connected to your restaurant's Wi-Fi.

## Setting up a Slave device

1. On the second device, select **POS**, then **Slave**.
2. Enter the Master device's connection address shown on its Connection & Terminals screen.
3. Confirm — once connected, you'll see the same floor plan and tables as the Master device.

## Checking connected devices

On the Master device, go to **Settings → Connection & Terminals** to see all currently connected POS, KDS, and Kiosk devices, along with their connection status.

<Tip>
  Both devices must be on the same Wi-Fi network to connect.

## What syncs automatically

Once connected, the following stay in sync across devices in real time:

* Table status and guest counts
* Orders, item additions, and modifications
* Void, comp, and gift actions
* Bill settlement — a table settled on one device frees up on the other automatically
* Order history

<Note>
  If a device briefly loses connection, it automatically catches up on any missed changes once it reconnects.
