™ (High Speed
Bus) Multiple Display
Systems
The High Speed Bus (
hsb
2
) provides extremely rapid transfer of data between
master and repeater displays. With an
hsb
2
and a SeaTalk connection most data
available can be controlled and displayed by any
hsb
2
unit in the system.
(Guard zones cannot be viewed or controlled on the chartplotter display, nor
on a repeater display that is not directly connected to a scanner. Likewise,
radar timed transmission is not available on a repeater display).
Master functionality is provided by the display with the appropriate
transducer connected as defined in Table 8-3 .
Any combination of
hsb
2
series displays is possible – each display could
provide different master functionality. Each display repeats the master
functionality of the other displays.
For example, you could connect an
hsb
2
Radar display and an
hsb
2
Fishfinder
display (which provides both fishfinder and chart functions), to enable you to
display and control radar, fishfinder and chart data on either or both displays.
You can display some combinations, such as radar/chart, in half-screen
windows.

Connection
Each
hsb
2
display is supplied with an in-line terminator fitted to the HSB
socket. When connecting two displays via
hsb
2
, plug the cable into the in-line
terminator on both displays.
When connecting more than two displays via
hsb
2
you must fit an
hsb
2
splitter
to at least one HSB socket. The splitter is fitted only to displays that are not at
the end of the chain, and when installing the splitter you must remove the in-
line terminator. Figure 8-12 illustrates the use of splitters and in-line
terminators in a multi-display system.
The displays must also be connected via SeaTalk (see SeaTalk® and NMEA In
