INSTALLATION NOTES
•
An NMEA FFD can be connected at any point on the system network. Typically an NMEA FFD is
mounted close to the NMEA device, e.g. at the chart table next to the GPS, thus minimising the NMEA
cable routes.
•
NMEA FFDs can be used in combination with all other display types, i.e. standard FFDs, Halcyon
displays, 20/20 and Pilot displays.
•
To prevent water intrusion into the display, do not cut the cable shorter than marked by the yellow band.
If it is necessary to cut cables, then the wires MUST be tinned with a soldering iron to ensure a proper
seal around the wires.
SCREENED CABLES
•
Shielded NMEA cables are supplied to provide protection against unwanted emissions (EMC) and must
be connected in accordance with these instructions.
•
NMEA cable shields must be connected at the TRANSMITTING end.
•
The NMEA output cable shield should be connected to the other cable shields in the junction box
supplied.
NETWORK TERMINATION
•
If the NMEA FFD is the last unit on the system network a network terminator MUST be fitted across the
network data wires, i.e. between the green and white wires. Only two network terminators are required
per system.
