Technical Application
Technical Application

OLED Screen with Touchpad

The conveniently located OLED (Organic Light-Emitting Diode) screen with touchpad allows maintenance personnel to check the diagnostics of the lantern with the touch of a button.

Bluetooth® Connectivity

Integrated Bluetooth® technology using the exclusive SealitePro® app allows for convenient in-field setup, configuration and maintenance from a location up to 50 metres away using your phone or tablet.

Satellite Communications

The SL-C510 is available with an optional integrated Iridium® Satellite module enabling two-way monitoring and control using the Iridium® Low Earth Orbit satellite network. Accessible via the Star2M® portal, the global Iridium® network offers genuine, pole-to-pole coverage and is the perfect communication partner for Sealite and our aids to navigation solutions.

Integrated, Internal AIS

Available as type 1 or type 3 and operating on the international VHF Marine Mobile Band for AtoN operational status and positioning information.

Available in three size configurations the SL-C510 provides an innovative and reliable solution for the 5-9NM range.
