6.4 Integrated Systems
The HSB series displays can be linked via the HSB network to transfer
chart and radar data between units; this enables a second, repeater
display to be used to view and control the chart or radar. The display unit
can also receive external signals to drive various features, such as the
North Up mode and waypoint display. These signals can be received
from equipment such as navaids, fluxgate (compass) sensors, and
SeaTalk data networks. The display unit can also transmit data.
Note: External equipment cannot be powered from the display’s
SeaTalk interface.
The display can communicate with other units connected via any of the
following three data standards:
• HSB™: High Speed Bus
An In/Out connector, for an HSB series repeater or radar display.
• SeaTalk
®
: Raytheon’s own SeaTalk
standard
An In/Out connector, normally used to transfer navigation and MOB
data. Also used for heading data (if not provided via NMEA). This
connection is necessary for full functionality between HSB series
displays.
• NMEA 0183: the National Marine Electronics Association (NMEA)
0183 interconnection standard, Version 2.3 April 1998. NMEA inputs
are compatible with earlier versions of NMEA.
Two NMEA/Power input connectors, normally used for non-SeaTalk
Compass (heading) data. Also used for navigation data (if not
provided via SeaTalk).
An NMEA Out connector, used to transmit navigation data.
A junction box is available to attach a SeaTalk GPS (or any other
SeaTalk instrument). This junction box enables the SeaTalk bus and
power to be connected to the GPS.
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,
