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.
