Settings

Configure model-supported settings for instruments connected to NaviGuard. Only settings with a documented control and confirmation path are available.

Model-dependent capability: Available information and controls depend on the connected instrument model and the installed NaviGuard software.

Before you start

Use this procedure only when the delivered NaviGuard documentation lists the setting for the connected model and provides an approved confirmation path. Otherwise, use the lantern connection for monitoring only.

Complete Set Up a Connected Lantern.
Confirm that the displayed model and variant match the installed lantern.
Record the confirmed values before changing a setting.
Change one setting at a time.

Lantern settings

Setting	Customer selection	NaviGuard behaviour
Nominal Range	Required range in nautical miles (NM)	Offers only values supported by the exact model profile and converts the selected NM value to the lantern-native setting.
Primary Flash Character	Readable character from the approved list for the selected model	Stores the normal flash character for the lantern.
Alternate Flash Character	Second readable character for a model that supports two stored characters	Stores the optional alternate character without exposing the manufacturer-specific code.
Select Active Character	Primary or Alternate	Changes which stored character the lantern uses when the connected model supports changeover.
Day/Night Switching	Switch On Below and Switch Off Above thresholds	Offers the units and permitted values defined by the selected model profile.

Nominal range

Select the required nominal range in NM. NaviGuard uses the confirmed model, variant, colour, optic, and flash character to determine the available values. A lantern-native power percentage is not shown as the normal customer setting.

If an approved conversion is not available for the selected lantern profile, Nominal Range is unavailable. Do not estimate a value from a percentage.

Parameter	Index	Range	Format	Default	Example
`NAGRANGE#`	1..6	Model-specific	Nominal range in nautical miles	-	`NAGRANGE1 5`

Flash characters

Select the primary character from the Flash Characters list. For models that support two stored characters, select an alternate character from the same list and choose which character is active. NaviGuard performs the model-specific mapping.

Primary flash character

Parameter	Index	Range	Format	Default	Example
`NAGFLASH#`	1..6	Flash Characters supported by the selected lantern	NaviGuard ID	-	`NAGFLASH1 <id>`

Alternate flash character

Parameter	Index	Range	Format	Default	Example
`NAGFLASHALT#`	1..6	Flash Characters supported by the selected lantern	NaviGuard ID	-	`NAGFLASHALT1 <id>`

Select active character

Parameter Index Range Format Default Example

NAGFLASHSEL#

1..6

0..1

0 = Primary

1 = Alternate

NAGFLASHSEL1 0

Day/night switching

Use Switch On Below to define when the lantern changes to its night operating state. Use Switch Off Above to define when it leaves that state. NaviGuard provides only the values and units supported by the selected model profile.

Switch on below

Parameter	Index	Range	Format	Default	Example
`NAGLUXON#`	1..6	Values supported by the selected lantern	Switch-on level in lux	Current lantern value	`NAGLUXON1 <lux>`

Switch off above

Parameter	Index	Range	Format	Default	Example
`NAGLUXOFF#`	1..6	Values supported by the selected lantern	Switch-off level in lux	Current lantern value	`NAGLUXOFF1 <lux>`

Replace # with the NaviGuard signalling slot from 1 to 6. Exact permitted values are supplied by the connected model profile. If that profile does not provide an approved range, the parameter is not available.

Operating-mode parameters are listed by lantern model under Supported Settings.

Apply a setting

Select the device slot and check the confirmed lantern model.
Select one available setting and choose an allowed value.
Submit the change.
Wait for bounded readback or the approved model-specific confirmation.
Continue only when the confirmed value matches the requested value.

Verify

The displayed value matches the requested value after readback.
Nominal Range is displayed in NM.
The permitted values match the connected lantern model and variant.
Only the settings listed for the connected model are available.

If a setting fails

Stop changing settings. Record the connected model, previous value, requested value, and displayed result. Recheck the model and communication setup before escalating the issue.
