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. You can disable the transmission of individual NMEA output sentences - refer to NMEA Out Set Up on page 7-9.

The SeaTalk input/output connection is detailed in SeaTalk Connection on page 8-27.

The NMEA output connector is a 4-pin connector as illustrated below. The

1.5m NMEA OUT cable has a ferrite clamp attached to ensure EMC conformance.

Data Conversion

The hsb2 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.

You can prevent NMEA heading data being bridged onto the Seatalk bus - refer to Bridge NMEA Heading on page 7-8.

Note: To transfer NMEA data, or to convert the data, the display must be pow- ered On.
