FAQs
Frequent questions
I have a B&G/SIMRAD device under warranty, who should I contact?
If you need technical service for your B&G/Simrad system under warranty, you must contact the following email: service.es@navico.com indicating the problem, the brand, model and serial number of your equipment.
What are the differences between NMEA 2000 and NMEA 0183?
An NMEA 2000 network consists of a completely different cable than the one used in NMEA183. It is bidirectional and therefore allows multi-transmission of serial data, thus being self-configurable.
The NMEA 2000 or N2K network consists of a main trunk from which branches are sent to the various devices by mounting “T” connectors at the Backbone points which also carries power to the devices.
NMEA 2000 is much faster than NMEA 0183, and any device can be removed or connected to the NMEA network without needing to reset the rest of the connected devices.
It also allows you to prioritise messages sent to the network depending on their importance.
Can you update maps?
Yes, depending on the equipment/brand/model, it is carried out differently.
I have no information on the speed of the boat
First of all, check if the system has only one sensor or two. If you have two, these are managed through a Gravity Switch.
a) If there is only one sensor: Remove the sensor from the thru-hull and rotate the paddle manually, check if it rotates well and if it marks the speed on the instrument.
If it doesn't, check with a voltmeter, measure between the black wire (negative) and the red wire (positive). The voltage should be between 5 and 12 volts, depending on which system it is, if there is no voltage, there is a failure in the control unit/processor.
If we have the voltage, measure between the black wire (negative) and the green wire (signal), and rotate the paddle slowly, there the voltage should change from 5-12 Volts to 0 Volts, if the voltage does not change, there is a fault in the sensor.
b)System with two sensors.
Check the connections on the gravity switch and verify its operation with a multimeter, the switch usually has a manual switch. Switch to both sides and check.
As a last resort, modify the wiring and make the direct connection between each of the sensors and the CPU in the same way as with a single sensor.
