The NMEA output connector is a 4-pin connector as illustrated below. The
1.5 m NMEA OUT cable has a ferrite clamp attached to ensure EMC
conformance.

Data Conversion
The display units convert some information across the communications links
as follows:
NMEA In to NMEA Out and SeaTalk
SeaTalk to NMEA Out
This enables data received by the display to be passed to other instruments. For
example, if you have a master and a repeater display, you only need to connect
NMEA In to the master display, which will pass the data to the repeater via
SeaTalk.
You can prevent NMEA heading data being bridged onto the SeaTalk bus -
refer to
Bridge NMEA Heading on page 4-9.
Note: To transfer NMEA data, or to convert the data, the display must be pow-
ered On.
