Data Output
Data is transmitted in SeaTalk and NMEA formats as detailed in Appendix D
and can be used to enhance other equipment as required.
The SeaTalk input/output connection is detailed on page163 .
The NMEA output connector is a 4-pin connector as illustrated below. The
1.5 m NMEA OUT cable is fitted with a ferrite clamp to ensure EMC
conformance.

Data Conversion
The HSB Series 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.
Note: To transfer NMEA data, or to convert the data, the display must be
powered On.
