What to do if my ACR Electronics GPS says 'AIS: External EPFS lost'?
If your ACR Electronics GPS displays the message 'AIS: External EPFS lost', it means no valid data is available on Ch1, Ch2, or Ch3. Check the sensor and its cabling to ensure they are properly connected. Verify that the system delivering the data is working correctly. Also, check the baud rate settings of the sensor inputs. Note that AIS requires the protocol NMEA 0183 V3.0!
What causes 'AIS: No valid SOG information' on my ACR Electronics GPS and how can I fix it?
The 'AIS: No valid SOG information' error on your ACR Electronics GPS indicates that there is no valid data from the external speed sensor or internal GPS. To resolve this, check the sensor and its cabling. Ensure the system delivering the data is working correctly. Verify the baud rate settings of the sensor inputs, as AIS requires the protocol NMEA 0183 V3.0!
What does 'AIS: No valid COG Information' mean on my ACR Electronics GPS?
The 'AIS: No valid COG Information' message on your ACR Electronics GPS means that there is no valid data from the external sensor or internal GPS. To fix this, check the sensor and the cabling, and make sure the system that delivers the data is working. Also, check the baud rate settings of the sensor inputs, ensuring they are correct, as AIS requires the protocol NMEA 0183 V3.0!
What does 'AIS: Heading lost/invalid' mean on my ACR Electronics GPS?
If your ACR Electronics GPS displays 'AIS: Heading lost/invalid', it means there's no valid data from the external sensor (Gyrocompass). Check the sensor and the cabling, and ensure the system delivering the data is working correctly. Verify the baud rate settings of the sensor inputs. Keep in mind that AIS accepts true heading only (no magnetic).
What does 'AIS: PRESS ENTER TO EXIT 1W/AUTO TX MODE' mean on my ACR Electronics GPS?
The message 'AIS: PRESS ENTER TO EXIT 1W/AUTO TX MODE' on your ACR Electronics GPS indicates that the conditions for enabling 1 Watt TX power are not valid. Check the conditions (SOG, Navstat, Shiptype) and ensure the GPS is providing valid data, as an invalid GPS signal can also trigger this alarm.
Why does my ACR Electronics GPS say 'AIS: Antenna VSWR exceeds limit'?
The 'AIS: Antenna VSWR exceeds limit' message on your ACR Electronics GPS indicates an issue with the VHF antenna or its installation. Check the antenna itself and the antenna cabling, ensuring that RG214 / 50 Ohm cable is used.
What to do if my ACR Electronics GPS displays 'AIS: No sensor position in use'?
If your ACR Electronics GPS shows 'AIS: No sensor position in use', it means there is no valid position data from the internal GPS or an external position sensor. Check the sensor cabling and the antenna of the internal GPS sensor.
What does 'AIS: No valid ROT Information' mean on my ACR Electronics GPS?
The message 'AIS: No valid ROT Information' on your ACR Electronics GPS means that either no Rate Of Turn indicator is in use, or there is no valid data from the external sensor. If a Rate Of Turn indicator is not in use, acknowledge the alarm. Otherwise, check the sensor and cabling, ensuring the system delivering the data is working correctly, and verify the baud rate settings of the sensor inputs, noting that AIS requires the protocol NMEA 0183 V3.0!
How to fix 'AIS: Tx malfunction' on ACR Electronics GPS?
To address the 'AIS: Tx malfunction' error on your ACR Electronics GPS, check if the antenna is AIS compatible (156-162 MHz). Also, inspect the antenna cabling for any short circuits or missing contacts at the connectors. If the ID 01 is displayed as a stand alone message, then the unit requires replacing.
What does 'AIS: ENTER MMSI NUMBER' mean on my ACR Electronics GPS and how to fix it?
The message 'AIS: ENTER MMSI NUMBER' on your ACR Electronics GPS means that no valid MMSI has been entered. Enter a valid MMSI to resolve this issue.
