Frequently Asked Questions

+How do I switch to NMEA display mode on my NRX200i remote when in stereo mode?

Simply press and hold the source button until the NMEA screen is displayed . To return to the Audio mode simply  press the menu button.

+What is the NMEA LEN rating for the NRX200i Remote?

The NRX200i Remote is rated LEN:3

+My Fusion-Link Wireless Application Displays “No Stereos Available”

The first thing to check is that you are connected to the correct wireless network for the 700 series. Once you have confirmed this  close the App on the device and restart it (consult the manufacturers website for instructions on restarting) . If this fails check that you have a valid IP address on the 700 series.

+What are my options for connecting FUSION remote controls to FUSION stereos?

MS-NRX200 Marine Wired Remote Controls can be installed throughout the vessel to provide full control of multiple FUSION Marine Stereos, creating flexible zone control and NMEA2000 monitoring solutions. The MS-NRX200 is a plug and play device with two connection options.

Connect the remote control to your FUSION Marine Stereo with the standard cable kit provided with your purchase. The standard cable kit supplied with your product in NOT NMEA 2000 compatible.

1 x 6M Extension Cable
2 x T-Connector
1 x Terminator (Male)
1 x Terminator (Female)

Note: If you install the remote control using the standard FUSION cable kit provided with the remote control, NMEA2000 repeater functions are not available

An existing NMEA 2000 network can be used to connect the remote control to your FUSION Marine Stereo. FUSION NMEA2000 connection kits are available separately for this purpose.

The FUSION cable kit MS-N2KCONN will be required for each FUSION device connected to the NMEA2000 network.
MS-N2KCONN - NMEA2000 Connection Pack
1 x NMEA2000 T-Connector
1 x Drop Cable FUSION to NMEA2000 Micro-C5

The remote control can be configured to display available NMEA2000 data on the network such as water depth, vessel speed and basic navigation data. Refer to xxxxx for a full list NMEA 2000 sentences displayed by the remote control.

+What marine devices or accessories are powered by the NMEA 2000 network?

FUSION uses the NMEA 2000 network to share data between devices and remote control devices. Our head units are powered using a directly connected power cable that is connected to the power source of the boat. Our NRX200 remote controls are powered from the NMEA 2000 network.

• MS-IP700 Marine Stereo for iPod (powered directly from supplied power cable)
• MS-AV700 Marine DVD Stereo (powered directly from supplied power cable)
• MS-NRX200 Remote Control and NMEA 2000 Display (powered from the NMEA 2000 network)

+What NMEA 2000 data does my NRX-200 Remote Control Display?

127250: Vessel Heading (Magnetic Heading, Correction, Deviation)
128259: Speed Water referenced (Speed Water, Speed Ground)
128267: Water Depth (Depth at transducer, transducer offset)
129025: Position Rapid Update (Latitude, Longitude)
129026: COG & SOG Rapid Update
129029: GNSS Position Data (Date, Time, Latitude, Longitude, Altitude)
130306: Wind Data (Speed, Direction, Reference)
130310: Environmental Parameters (Water Temperature, Outside Ambient Air Temp, Atmospheric pressure)
130311: Environmental Parameters (Deprecated) (Temperature Instance, Humidity Instance, Temp, Humidity, Atmospheric Pressure)
130312: Temperature (Instance, Source, Actual)
130314: Actual Pressure
130577: Direction Data (Course Over Ground, Speed Over Ground, Heading, Speed Through Water)
129284: Navigation Data (ETA)

+What FUSION marine devices and accessories are NMEA 2000 Compatible?

FUSION makes devices that are NMEA 2000 compatible. These devices use NMEA 2000 to communicate with each other. NMEA 2000 is a faster language protocol than NMEA 0183 and will allow much more data to be shared between devices.
Here is a list of NMEA 2000 compatible FUSION products:

• MS-IP700 Marine Stereo for iPod

• MS-IP700i True Marine Entertainment System for iPod

• MS-AV700 Marine DVD Stereo

• MS-AV700i True Marine Entertainment System for DVD

• MS-NRX200 Remote Control and NMEA 2000 Display

• MS-NRX200i Remote Control and NMEA 2000 Display

• MS-RA205 True Marine Stereo

+My FUSION-Link wireless remote Application will not connect to my 700 series stereo.

The first thing to check is that the 700 series is displaying a valid IP address on the about screen. Select the settings menu then about to confirm. If the display is " IPNone " the router is either not a compatible DHCP product or not configured correctly. If the IP address starts with the prefix 169. it is not valid, this is a default address when the router is not sending a DHCP generated IP address or is configured incorrectly.Please review the Router's instruction manual or contact the manufacturers website for technical help.
