How do I control a B&G, Lowrance or Simrad autopilot?

This is a non-exhaustive list of the Navico autopilots that we support:

  • NAC-1, NAC-2, and NAC-3

  • B&G H5000

  • TP22 and TP32 via SimNet adapter cable

  • Simrad AC1x, AC4x and AC7x series directly via NMEA2000 or SimNet adapter cable

Supported autopilot modes and actions

The following modes and actions are supported:

  • Standby - Disengages the autopilot.

  • Auto / Heading Hold - Maintains a fixed heading.

  • No Drift - Maintains a track over ground.

  • Wind - Maintains a specific wind angle rather than a fixed heading.

  • Navigation (Nav) - Follows an active route.

  • Autotack

  • Autogybe

Using Navigation (Nav) mode

For Nav mode to work, you'll need to set Orca as your navigation data source on your autopilot's head unit display.

This allows the autopilot to follow routes provided by Orca.

Can I control my autopilot using both Orca and the autopilot's control head?

Yes! You can use both the Orca App and your autopilot's control head to control a compatible autopilot.

While the autopilot can receive control commands from either device, it can only use one navigation data source at a time.

If you want your autopilot to follow an Orca route, make sure Orca is selected as the navigation data source.

TP22 and TP32 must be set into "System mode" for control via Orca. If the TP22 or TP32 are put into another mode such as "Port Side Mounting Mode" control via Orca will not work. To activate System Mode, press and hold the TACK, STBY/AUTO and NAV keys while turning power on to the autopilot.

Simrad AC2x autopilots connected via AP2x or AT10 are not supported. Autopilot controls won't work as these Simrad AP2x or AT10 don't broadcast to the NMEA 2000 network
​

It might still be possible for these autopilots to use navigation data from an Orca Core (follow Orca routes). This depends on the converter, please check the converter documentation in advance.
