Fault 555 & 554 – GPS & NMEA

Overview

Seakeeper Ride requires a continuous, reliable GPS signal to function. The faults in this section are Seakeeper Ride communicating that this requirement has not been met, which could have multiple causes.

Fault 555 – LossGPSFix

Fault 555 indicates that Seakeeper Ride detects connection to a valid NMEA 2000 network but does not detect a valid GPS fix (i.e., no good GPS signal is being received).

It may be helpful to verify that the GPS is present and has a fix (good signal) according to the MFD by viewing signal strength in the GPS, Satellite, or Device settings depending on your MFD.

Causes and Solutions:

  1. Boat is indoors, under a bridge, or too close to other nearby large structures.
  2. The GPS antenna is blocked by structure or has interference with equipment on the boat. This could be T-tops, bimini tops or other coverings, consoles, other equipment near the GPS, etc.
  3. GPS antenna is defective or broken.
  4. NMEA 2000 cable or tee is defective or broken.
  5. Main MFD unit is mirrored to another unit causing GPS or NMEA 2000 issues.
  1. Move the boat outdoors or away from potential obstructions.
  2. Relocate the GPS on the boat for better line of sight to the sky.
  3. Repair or replace GPS antenna.
  4. Replace suspect NMEA2000 cable or tee.
  5. Restructure NMEA 2000 connection between the MFDs. Change or cancel mirroring settings.

Fault 554 – NMEA2000Fault

Fault 554 indicates that Seakeeper Ride detects no connection to the NMEA 2000 network, and consequently, no connection to a valid GPS device.

Causes and Solutions:

  1. Cable between Software Module and NMEA 2000 network is loose or damaged.
  2. Boat’s NMEA 2000 network is not correctly assembled.
  3. Main unit is mirrored to another unit causing GPS or NMEA2000 issues.
  1. Check cable between Software Module and NMEA 2000 network. Replace if needed.
  2. Restore power to the boat’s NMEA 2000 network.Install terminators on the ends of the boat’s NMEA2000 network.
  3. Verify Ride is visible on NMEA 2000 network. Restructure NMEA 2000 connection between the MFDs. Change or cancel mirroring settings.
