IP Troubleshooting

To effectively address connection issues between the main cashier and other devices (Sub Cashiers, KDS, CDS, Notifier, Printers), please follow the troubleshooting steps below and avoid unrelated solutions such as:

Order Pending Sync

Using Cellular Data

Offloading the Cashier App

Deleting and Reinstalling the App

When Does This Issue Occur?

Typically after a router is powered off/on (e.g., due to electricity issues).

This may change the IP addresses of connected devices, causing communication issues.

Common Error Messages

Root Cause

This is strictly an IP address issue – not related to app performance or sync problems.

How to Fix the Issue

1. For Issues Between Main Cashier and Sub Cashier / Other Devices:

Get the IP address of the Sub Cashier:

From the Sub Cashier: Home > Diagnostics

If not accessible due to error (URL session timeout), go to:

Sub Cashier/other device iPad Settings > Wi-Fi > Tap the blue (i) icon > Scroll to find the IP address

On the Main Cashier:

Go to: Home > Devices > Edit Sub Cashier

Insert the IP address of the Sub Cashier/Other device

Tap Save > Tap Ping

You should see "Successful" in green

ENSURE both iPads have Foodics Cashier opened when clicking PING 

2. For Issues Between Main Cashier and Printer:

Find the printer’s IP address:

Refer to the COE HC for getting the IP address of certain printer

Once you have the IP:

Go to: Main Cashier > Home > Devices > Edit Printer

Insert the printer’s IP > Tap Save > Tap Ping

The printer will print a small paper confirming the connection

Important Settings Check

Ensure Local Network is enabled on all iPads:

Settings > Foodics Cashier > Enable "Local Network"

How to Activate Local Network for Cashier App

If the Above Steps Don't Work: Reset Network Settings

On each iPad:

Settings > General > Transfer or Reset > Reset > Reset Network Settings

The iPad will restart and disconnect from Wi-Fi

Reconnect all devices to the SAME network
