Connecting NMEA0183 equipment
There are two methods for connecting the SMD7/9 with NMEA0183 equipment:
• Connected directly via the NMEA0183 port at the rear of the unit. This method is
recommended for single connections.
• Via the CAN bus network, using the optional NMEA data converter (IF-NMEA2K2).
This method is recommended when connected with multiple NMEA0183 devices.
The NMEA0183 connection baud rate, on the external equipment, must be set to ei-
ther 4800 bps or 38400 bps.
Heading input allows functions such as Radar Overlay and course stabilization (North
up, Course up, etc.) in the radar operating modes. The NMEA0183 heading refresh
rate needs to be 100 ms in order for any radar function to work properly. NMEA0183
heading can be accepted at either baud rate shown above.
Note: For more information on connecting and wiring IF-NMEA2K2, refer to the instal-
lation manual for the IF-NMEA2K2 (IMC-44591-xx; “xx” indicates publication version).
2.2 XDR Port
Connect the transducer to the XDR port on the rear of the display unit. If the optional
speed/temperature sensor is connected, connect the transducer with the optional ca-
ble assembly (type: 02S4147).
Note: Use of the optional extension cable (type: C332 10M) may cause the following
problems:
• Reduced detection ability
• Wrong ACCU-FISH
™
information (fish length smaller than actual length, fewer fish
detections, error in individual fish detection)/
• Wrong speed data
• No TD-ID recognition

2.3 NMEA2000 (CAN bus) Connections
What is CAN bus?
CAN bus is a communication protocol (NMEA2000 compliant) that shares multiple
data and signals through a single backbone cable. You can simply connect any CAN
bus devices onto the backbone cable to expand your network on-board. With CAN
bus, IDs are assigned to all the devices in the network, and the status of each sensor
in the network can be detected. All the CAN bus devices can be incorporated into the
NMEA2000 network.
The table below shows the NMEA2000 devices which are compatible (connectible)
with the SMD7/9 and can share information via the CAN bus network.
Note: For NMEA0183 connections, see section 2.1.
