High Speed Bus ( hsb

)
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 unit.
Master functionality is provided by the display with the appropriate
transducer/scanner connected as defined in
Table 2-3 . You can have a master
fishfinder and a master radar in the same system. Data on master units are
displayed on all connected repeater units.
Note: For the DSM250 to operate properly, the display unit must be set up as
the Repeater unit in the Sonar Setup menu. See Section 4.4.
The
hsb
2 Network
Up to ten
hsb 2
Plus Series units can be combined to create a variety of
functionalities. For example, you can connect your L770D/RC Plus or
L1250D/RC Plus Fishfinder to the DSM250 and then to a remote
hsb
2
Series
Pathfinder Plus Radar and a remote
hsb 2
Series Plus Chartplotter to provide
fishfinder, chart, and radar functionality on all three displays. You can display
some combinations, such as fishfinder/chart or radar/chart, in half-screen
windows.
Note: Fishfinder STC cannot be adjusted on a repeater (non-HD Series) dis-
play, nor can depth offset, speed and temperature calibration be set. Frequen-
cy can be selected on either master or repeater, but the same frequency is used
on all displays.
The hsb
2
system can include several chartplotter displays, each with two chart
cartridge slots. Each display can access two local and up to six remote chart
cartridges. Charts can be controlled
independently on each display, even when
a remote chart cartridge is being used.
