Connecting to a NMEA device
You can connect the Fishfinder 400C to another piece of NMEA
compatible electronic equipment, such as a Garmin GPS (Global
Positioning System) device. If equipped with a capable transducer,
the Fishfinder 400C can send depth, temperature, and speed
information. Refer to the wiring diagrams on
the Fishfinder 400C to NMEA compatible devices.
To install the wiring harness to a GPS or other NMEA
device:
1. Follow the voltage source installation steps (see page 10).
For Garmin units, the ground (Black) wires serve as NMEA
ground and must be attached together or on the same
terminal. Refer to the wiring diagram of your GPS unit for
wire identification.
2. Connect the Blue (NMEA Out) wire from the Fishfinder 400C
to the NMEA In wire on the GPS/NMEA unit's wiring harness.
3. Turn on the Fishfinder 400C NMEA Output setting (page 23).
For Garmin GPS units, set the communications interface to
NMEA/NMEA, NMEA In/NMEA Out, or NMEA.
Interfacing with NMEA
The Fishfinder 400C allows for NMEA 0183, Version 3.01 output
with a compatible GPS or navigation device. You must set NMEA
Output On to send data
(page
page 11
for connecting
23).
The SDDBT, SDDPT, SDMTW, SDVHW, SDWPL sentences are
sent in NMEA 0183, Version 3.01 output from the Fishfinder 400C.
You can purchase complete information about National Marine
Electronics Association (NMEA) format and sentences from:

Installing the Fishfinder 400C to a Garmin CANet
The Fishfinder 400C is a CANet-compatible sonar device.
Using the CANet (if applicable) optimizes the performance of
CANet-compatible units, allowing sonar information from the
Fishfinder 400C to be shared with up to two CANet compatible
Garmin GPS units. A standard NMEA connection only allows
depth, temperature, and speed information to be sent to a single GPS
device, whereas a CANet connection provides full sonar readings,
including Ultrascroll
, so you can view and control the same
™
information on your compatible GPS unit(s) as you can on your
Fishfinder 400C.
NOtE: To use the Garmin CANet with your Fishfinder 400C,
you must obtain a CANet Kit. Contact your Garmin dealer, or
visit www.garmin.com.
