Note: If you wish to practice using the units before installation, connect the
HSB cable from the sounder module to the display and use the simulator
mode, as described in Section 3.4 Simulator Mode.
If you are connecting your display to other equipment (including an hsb
2
Plus
Series display unit) install then test the fishfinder display and transducer as
described in this chapter. Once the display is operating correctly, you can
connect it to other equipment as described in
Section 2.9Integrated Systems
on page 2-24, taking particular care to ensure the correct polarity of the
SeaTalk supply.
Section 2.9 describes the
hsb 2
, SeaTalk, and NMEA
interfaces.
For the system to display depth, water temperature and speed, you must install
the transducer type(s) capable of transmitting the appropriate data.
For full functionality of the radar and chartplotter you need to provide position
and heading data.
• Heading data enables the chart to operate in North Up and Course Up
modes. If speed data is also available the MOB function operates.
• Position data is required for full functionality of the chart display.
Full details of heading, position and other data are given in Section 2.9.
