4 HSB Series LCD Display

Display Unit

The HSB Series LCD display unit is waterproof to CFR46 and can be installed
either above or below deck.
The unit includes:
• 7" LCD display
• Trackpad
• Eleven dedicated (labelled) control keys
• Four soft keys (unlabelled) whose functionality changes
• The chartplotter (RC520) and combined Pathfinder Radar/Chartplotter
(RL70RC) include two slots for the C-MAP NT ® electronic chart cards
The display and keys can be illuminated for night-time use.
The HSB (High Speed Bus) connection enables transfer of data between two
compatible units. For example, the radar data is transferred from the radar (the
master display) via the HSB connection and can be displayed and controlled on
any other HSB Series LCD or CRT display (repeater display). In particular, you
can connect your HSB Series Pathfinder Radar to a remote HSB Series
Chartplotter to provide similar functionality to the combined Pathfinder Radar/
Chartplotter.
Full functionality of the HSB Series Pathfinder Radar is acheived when it is part
of an integrated system, with other equipment (in addition to another HSB unit)
connected via Seatalk or NMEA 0183. Data from this equipment including
position and waypoints is displayed on the radar and is used in calculations.
Details on connecting other equipment are given in Chapter 8.

Scanner

The HSB Series Pathfinder Radar is supplied with either a scanner unit which
illuminates targets with microwave energy and then collects the returns from
those targets. The scanner includes a sensitive low-noise front end receiver, and
a variety of clutter attenuation controls to maintain target resolution.
Installation of the scanner is described separately in the Scanner Owner's
Handbook. The scanner is adjusted and operated from the display unit, so these
details are provided in this HSB Series LCD Display Handbook.
The scanner can be switched between transmit and standby modes. It also has a
power-saving timed transmit mode which pauses between bursts of
transmissions.
