SL72RC PLUS Combined Radar/Chartplotter Display
On the SL72RC PLUS Combined Radar/Chartplotter, 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 SL72 and SL72RC PLUS displays 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 7-9 .
Note: To transfer NMEA data, or to convert the data, the display must be pow-
ered On.
