The Receive NMEA 2000 Alerts feature brings supported alerts from compatible devices on your boat’s NMEA 2000 network into the Vanemar App. The Vanemar NMEA 2000 Boat Adapter receives these alerts and passes them to the Vanemar system. Depending on their type and your settings, they appear as alarms or warnings in the app.
This allows supported alerts from compatible onboard devices to be viewed remotely in the Vanemar App, including alerts that would otherwise only be available on the boat’s onboard displays.
How NMEA 2000 alerts reach Vanemar
A compatible onboard device generates an alert.
The device publishes the alert on the boat’s NMEA 2000 network.
The Vanemar NMEA 2000 Boat Adapter receives the alert and forwards it to the Vanemar Gateway.
Enabled alert types appear in the Vanemar App as alarms or warnings.
Note: An alert appearing on a device’s own screen does not necessarily mean it is published on the NMEA 2000 network. To appear in Vanemar, the source device must publish a supported NMEA 2000 alert message.
What you need before you start
A Vanemar Gateway.
A Vanemar NMEA 2000 Boat Adapter, paired with your Vanemar system and connected to your boat’s NMEA 2000 network.
A compatible device that publishes supported NMEA 2000 alert messages.
A powered and properly terminated NMEA 2000 backbone.
Vanemar Gateway firmware 2.8.3 or later and an up-to-date Vanemar App.
Notes
The Vanemar Gateway alone cannot receive alerts from the NMEA 2000 network. The Vanemar NMEA 2000 Boat Adapter is required.
The Gateway communicates wirelessly with the Boat Adapter. No physical cable connection is required between them.
Supported alert types
NMEA 2000 alerts of the Emergency Alarm type are displayed as alarms in Vanemar.
NMEA 2000 alerts of the Alarm, Warning, and Caution types are displayed as warnings in Vanemar.
How alarms appear in Vanemar
Enabled Emergency Alarm alerts appear on Vanemar’s alarm screen alongside other alarms, with a red alert icon.
An alarm entry can include:
Alarm description.
Date and time.
Location description provided by the source device.
Alert type.
Source device information, identified as received via NMEA 2000.
Location and source device information are shown when available.
How warnings appear in Vanemar
Enabled Alarm, Warning, and Caution alerts appear in your boat’s Warnings section, with a yellow alert icon.
Tap a warning to open its details. Depending on the information provided by the source device, the details can include:
Alert description.
Location description.
Alert type and category.
Source device information.
Date and time.
The details screen also includes an NMEA 2000 Alerts link that takes you directly to the settings for managing the alert types you receive.
How to customize the alert types you receive
Open the NMEA 2000 Alerts settings
Open the Vanemar App.
Tap the menu button in the top-right corner.
Select your boat.
Tap Security Settings.
Tap NMEA 2000 Alerts.
Enable alerts and choose the types you receive
Turn on Show Alerts in Vanemar, then choose which alert types you want to receive using the individual controls below it.
Turn on Show Alerts in Vanemar.
Under Types Shown as Alarm, enable or disable Emergency Alarm.
Under Types Shown as Warning, enable or disable Alarm, Warning, and Caution independently.
Tap Save and wait for the operation to complete.
For example, you can enable only Emergency Alarm to display NMEA 2000 emergency alarms in Vanemar, or also enable Warning to receive that type in the boat’s Warnings section.
Note: Turning on Show Alerts in Vanemar does not automatically enable every alert type. You must also select the types you want to receive.
Disable all NMEA 2000 alerts
To stop receiving all NMEA 2000 alert types, turn off the main Show Alerts in Vanemar switch.
Turn off Show Alerts in Vanemar on the NMEA 2000 Alerts settings screen.
Tap Save.
Turning off this option disables all alert types. When you turn it back on, select the types you want to receive again.
Clearing NMEA 2000 alarms in Vanemar
Clearing a received NMEA 2000 alarm in Vanemar clears it only within Vanemar.
Important: This action does not acknowledge or silence the alarm on the NMEA 2000 network. Check the relevant onboard device or system and use its own controls to take any required action.
If alerts are not appearing
Check that the Boat Adapter is paired with your Vanemar system and connected to the NMEA 2000 network.
Make sure the NMEA 2000 network and the source device are powered on.
Confirm that the source device publishes the alert as a supported NMEA 2000 alert message.
Check that Show Alerts in Vanemar and the relevant alert type are enabled.
Make sure you have saved your settings.
Make sure your Vanemar Gateway is running firmware 2.8.3 or later. If it is running an earlier version, update the firmware and try again.
