How do I connect to a Simrad or B&G radar?
Updated over a week ago

Radar support is an advanced functionality of Orca Core. It allows you to view a Radar Overlay on your Orca Charts and control your Simrad or B&G radar directly via Orca. Simrad and B&G radars are brands made by Navico, so this article will refer to Navico radars.

Radar controls in Orca integrate seamlessly with your existing Navico chartplotter. Any change you make in Orca will also be reflected on your other systems that are connected to your Navico radar.

Orca supports connecting to the following Navico radars:

  • HALO 24, 20+, 20, 8, 6, 4

Only Orca Core 2 (which has two cables) supports connecting to Navico radars.

Supported functionality

All basic controls are supported, from changing modes to range, sensitivity, and noise reduction. The following functionality is not yet supported but will be added in the future:

  • Doppler / VelocityTrack color coding

  • Guard zones

  • Target trails

  • Setup sector blanking

  • Setup heading offset

For dual-range radar setups, Orca will connect to the primary radar configuration.

Connecting to a Navico radar

Orca supports the following connection topologies:

  1. Connection via a Switch – such as the Navico NEP Switch or a standard Ethernet switch

  2. Direct connection – an Ethernet cable between the radar and Core

Once connected, Orca will automatically detect the Radar and show Radar Controls in the Control Center. For information about controlling your Radar, see the relevant article.

Connection via a Switch

Connection via an Ethernet switch is recommended for when you have multiple devices controlling your Radar.

For connection to a switch, you will need:

  1. An M12 male to RJ45 female adapter¹

  2. Option A: If you use a standard Ethernet switch, you'll need a male-to-male RJ45 Ethernet cable

  3. Option B: If you use a Navico Ethernet switch, you'll need a Navico 5-pin ethernet female to RJ45 male adapter cable²

Direct Connection

Direct connection is only recommended if you do not intend to access the Radar from any other devices.

For direct connection, you will need:

  1. An M12 male to RJ45 female adapter¹

  2. A Navico 5-pin ethernet to RJ45 male adapter cable²

Recommended connection equipment

  1. M12 male to RJ45 female adapter: We recommend the following high-quality and cost-effective alternatives:


    - Amphenol RJS-12D04FM-RS8001 (Mouser webshop)
