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; for example at the chart table next to
the GPS, thus minimising the NMEA cable routes.
•
NMEA FFD's can be used in combination with all other display types; that is standard
FFD's, Halcyon displays, 20/20 and Pilot displays.
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, that is between the green and white wires. Only two network
terminators are required per system.
