Connecting the HawkEye FishPod 10BX (FP10BX) to an NMEA 0183 Compatible Device Follow

To set up the HawkEye FishPod 10BX (FP10BX) with an NMEA 0183 system, you need to correctly connect its four wires: BLACK (GND), GREEN (VCC), RED (0183-), and WHITE (0183+). Proper connections ensure reliable communication between the FishPod 10BX and other marine devices like chartplotters or GPS systems.

FP10BX Data Capabilities

The FP10BX has the ability to supply depth and water temperature readings to an NMEA 0183 network. These readings, calculated by the FP10BX, will display on the connected device. However, it is important to note that the FP10BX does not transfer raw sonar data or imaging. For viewing detailed sonar data and images, you must use the FishPod App.

FP10BX Wire Functions in an NMEA 0183 System

1. Power Wires:

   • GREEN (VCC): Supplies 12 volts of Positive DC power (VDC +) from the FP10BX to the connected device.
   • BLACK (GND): Supplies 12 volts of Negative DC power (VDC -) from the FP10BX to the connected device.

2. Signal Wires:

   • WHITE (0183+): Transmits the positive side of the NMEA 0183 data signal.
   • RED (0183-): Transmits the negative side of the NMEA 0183 data signal.

Steps to Connect the FP10BX Wires

1. Identify Wire Colors and Functions

• The FP10BX wire colors are defined as:

  • GREEN: VCC (Power)
  • BLACK: GND (Ground)
  • RED: 0183-
  • WHITE: 0183+

• Confirm the wiring colors and functions on the NMEA 0183 device you are connecting to by referring to its manual. Typical receiving device colors might differ.

2. Connect Power Wires

• If your external device has its own power supply, the GREEN (VCC) and BLACK (GND) wires from the FP10BX do not need to be connected. In this case, cap off the unused wires with heat shrink tubing to insulate them and secure them with a zip tie to avoid interference or damage.

• If your external device does not have its own power supply:
  • Connect the GREEN (VCC) wire from the FP10BX to the 12 VDC + wire of the connected device.
  • Connect the BLACK (GND) wire from the FP10BX to the 12 VDC - wire of the connected device.

3. Connect Signal Wires

• Link the WHITE (0183+) wire from the FP10BX to the RX+ (or equivalent) input on the receiving device.
• Link the RED (0183-) wire from the FP10BX to the RX- (or equivalent) input on the receiving device.

4. Secure Connections

• Use marine-grade connectors or terminal blocks for durability and resistance to corrosion.
• Protect the connections with heat-shrink tubing or waterproof tape to prevent water ingress and electrical shorts.

5. Test the System

• Power on the devices and verify communication between the FP10BX and the receiving device.
• Confirm data is being sent and received without errors.

Additional Considerations

1. Differential Signaling:

   • The FP10BX uses differential signaling for its NMEA 0183 communication. Ensure proper alignment of positive and negative lines.

2. Multiple Receivers:

   • If multiple devices need to receive data from the FP10BX, use an NMEA buffer or multiplexer to avoid signal overload.

3. Electrical Isolation:

   • Use optoisolators or galvanic isolators to prevent ground loops and ensure safe operation in electrically noisy environments.

4. Cable Management:

   • Secure and route cables away from potential sources of interference, such as AC power lines or motor circuits.

Troubleshooting Tips

• No Data Transmission: Check the WHITE and RED connections, ensuring they’re not reversed.
• Power Issues: Confirm the GREEN wire is receiving the correct voltage and ensure the BLACK wire has a solid ground connection.
• Data Errors: Look for loose connections or interference sources affecting the signal.
