Upgrading Existing HSB Series Displays
Earlier HSB (non-PLUS) display units can be upgraded to provide
hsb
2
Plus
compatibility. Two types of upgrades are available:
1. A full hardware and software upgrade (Plus upgrade) provides full com-
patibility with the
hsb
2
system.
This configuration supports up to eight true Plus (or Plus upgraded) dis-
plays with a cable limit of 60 meters, or up to ten true Plus (or Plus
upgraded) displays at a maximum of 40 meters cable length.
2. A software-only upgrade enables the display to be used with a Plus (or Plus
upgraded) unit in the
hsb
2
system.
However, like the old HSB (non-Plus) system, this configuration only sup-
ports two displays: two software-only upgraded units, or one software-
only upgraded with one true Plus (or Plus upgraded) display.
Connecting
hsb
2
Plus Series Displays
Figure 2-11 illustrates how to inter-connect various
hsb
2
Plus Series Displays.
When connecting your
hsb
2
Plus Series displays, there are several important
points to keep in mind:
1. If more than two
hsb
2
Plus Series displays are to be connected, you must
use an
hsb
2
Splitter Cable, Raymarine part number E55040.
2.
hsb
2
displays at the end of the chain must be terminated using the Inline
Terminator plug (Raymarine part number R58117) included with your
hsb
2
Plus Series display unit.
