Comm Error

This section covers if you receive a "Comm Error" error message on the device.

Use this when an Engage device shows a "Comm Error" or "Communication Error" message.

Symptoms

• "Comm Error" or "Communication Error" displays on an Engage device.

Most likely cause: a failed connection between the device, the internet, or the POS — not a sign the device itself is faulty. This can be caused by an internet outage, a faulty or disconnected cable, an IP address mismatch, or incorrect device settings, among others.

Resolve the issue

1

Check the cables

Verify all cables — including Ethernet cables — are securely seated. If any are loose, unplug and reseat them firmly.

✅ Issue fixed — stop here. ❌ Still not working — continue to the next step.

2

Verify the internet connection

Confirm there's no internet outage, the signal is strong, and there are no red lights on the router.

✅ Issue fixed — stop here. ❌ Still not working — continue to the next step.

3

Reboot the device

Hold the red X button until a prompt appears, then select Reboot.

✅ Issue fixed — stop here. ❌ Still not working — continue to escalation below, or see Engage Comm Error Diagnostics for deeper troubleshooting.
