Chapter 2: Installing the Scanner 37
Display unit connection
CAUTION:
Do not use an open array scanner with an SL70 or Autohelm 7"
LCD display unit. Failure to observe this may result in
permanent damage to the display unit.
10 kW open array scanners cannot be directly connected to 12 V
systems.
The rear of the Pathfinder display includes the following connection
sockets:
• Scanner connection
• Power/NMEA Input DC power connection, two NMEA 0183
inputs and one RF ground (screen) connection.
Note: If you have an integrated system that includes a radar display
with MARPA as a primary function, the scanner must be connected to
this display to enable the function. MARPA is then available on any
repeater display.
Connect the scanner cable to the scanner connector and power to the
power/NMEA input connector.
Power and all other connector details are supplied in the display unit
Owner’s Handbook.
