GARMIN GNA 10 Jog Lever Adapter
Important Safety Information
 |
| See the Important Safety and Product Information guide in the product box for product warnings and other important information |
| You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid navigational hazards and never leave the helm unattended. |
| Always be prepared to promptly regain manual control of your boat. |
| Learn to operate the autopilot on calm and hazard-free open water. |
| Use caution when operating the autopilot near hazards in the water, such as docks, pilings, and other boats. |
 |
| When in use, beware the risk of entrapment or pinching from moving parts. |
| Failure to install and maintain this equipment in accordance with these instructions could result in damage or injury. |
 |
| To avoid damage to your boat, the autopilot system should be installed by a qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper installation. |
Tools and Supplies Needed
- Wire cutters/strippers
- Waterproof wire connectors (wire nuts) or heat-shrink tubing and a heat gun
- Cable ties
- Jog lever or switch to connect to the system
Compatible and Recommended Jog Levers and Other Devices
This device has been tested and confirmed to be compatible with the jog lever models listed below, and complete wiring and configuration details for these models are provided in these instructions. Jog levers from other manufacturers may work with this device when connected and configured using these instructions, but compatibility cannot be guaranteed.
- Jastram™ JO100-1 and JO300-1
- Kobelt™ 7170
- Simrad™ S35
When selecting a switch to use with this device, consider these guidelines.
- A single-pole, single-throw (SPST) switch, either latching or momentary, can be used to trigger actions.
- A switch rated for IEC IP67 is recommended to best withstand installation and use in a marine environment.When selecting an indicator light to use with this device, consider these guidelines.
- Although both incandescent and LED indicator lights are compatible, an LED indicator is recommended because LED indicator lights last longer and require less power to operate.
- The output signals from this device when using wiring harness A as directed are regulated to 22 mA max. You can use most LED indicator lights without installing a current limiter.
- An indicator light rated for IEC IP67 is recommended to best withstand installation and use in a marine environment.
Installing the Adapter
You can use this adapter to connect an external device to the autopilot system, such as a jog lever, a normally open momentary or latching switch, or an indicator light.NOTE: You can install only one jog lever per GNA 10 adapter. If you have multiple jog levers, you must install a separate adapter for each jog lever.
- Mount the external device according to the instructions provided with the device.
- Connect the bare wires from the external device to the GNA 10 adapter (Wiring Connections, page 1).
- Repeat the previous two steps for additional external devices, if necessary.
- Connect the GNA 10 adapter to the same NMEA 2000® network as the autopilot system (NMEA 2000 Connection Considerations, page 2).
- Configure the behavior of the connected devices in the software (Configuring the Adapter on a Chart plotter, page 2).
Wiring Connections
You should connect your device or devices using the harness with the A label only. The harness with the B label is reserved for future use. The wires are organized in pairs, and each input and output channel has both a positive (+) and negative (-) wire. You should always connect your device using both wires in the pair. If you need to extend these wires, you should use 24 AWG (0.2 mm2 ) wire. You should use solder and heat-shrink tubing when connecting your device to these wires.
Wiring Harness A

| Input 1 | Brown (+) Black (-) |
| Input 2 | Yellow (+) Black (-) |
| Input 3 | Blue (+) Black (-) |
| Output 5 | Green (+) Violet (-) |
| Output 6 | Red (+) Orange (-) |
| Output 7 | White (+) Gray (-) |
Wiring Harness B (Reserved for Future Use)
| Function | Wire Colors |
| Input 4 (request) | Red (+) Black (-) |
| Output 8 (acknowledge) | White (+) Green (-) |
| Drain (ground) | Clear |
NMEA 2000 Connection Considerations
You must connect the GNA 10 device to the same NMEA 2000 network as the other Garmin® autopilot components. If you are unfamiliar with NMEA 2000, you should read the Technical Reference for NMEA 2000 Products at garmin.com/manuals/nmea_2000..

Configuration
After connecting the GNA 10 adapter, you must configure it for use with the autopilot system. You can configure the adapter using a connected helm control or compatible chartplotter.
- Configuring the Adapter on a ChartplotterSelect Settings > Communications > NMEA 2000 Setup >Device List.
- Select the GNA 10 adapter.
- Select Review > Configuration
- Select the input or output channel you want to configure, and select Set Action.
- Select an action for the input or output wire (Adapter Configuration Options, page 2).
- To test the configuration, perform the action you selected for the input or output channel. If the channel is configured correctly, the Status for the channel changes to High.
Configuring the Adapter on a Helm Control
- Select Menu > Setup > NMEA 2000 Devices.
- Select the GNA 10 adapter.
- Select Configuration
- Select the input or output channel you want to configure, and select Action.
- Select an action for the input or output wire (Adapter Configuration Options, page 2).
- To test the configuration, select the input or output channel and select Information.
- Perform the action you selected for the input or output channel. If the channel is configured correctly, the Status for the channel changes to High.
Adapter Configuration Options
The options available for the GNA 10 adapter are different for input and output wires.NOTE: You can install only one jog lever per GNA 10 adapter. If you set a channel to Jog Lever Port or Jog Lever Starboard, you cannot set another channel on the adapter to the same action.No Action (input and output): Sets the channel so that it does not send or receive any signals.Jog Lever Port (input): Sets the channel to receive a port steering signal from a jog lever.Jog Lever Starboard (input):Sets the channel to receive a starboard-steering signal from a jog lever.Autopilot Heading Hold/Standby (input): Sets the channel to receive a signal to toggle the autopilot between heading hold and standby. You can specify the type of signal switch as either momentary or latching.Momentary: Should be selected for a type of switch, typically in the form of a push button, that engages only when the switch is pressed, and disengages when the switch is released.Latching: Should be selected for a type of switch that toggles between two positions, like a light switch. When the switch is moved to the closed position, the input action is activated until the switch is moved back to the open position.Autopilot Standby (input): Sets the channel to receive a signal to place the autopilot into standby.Autopilot Engage Status (output): Sets the channel to output a signal indicating that the autopilot is engaged.
