RI10 Connections

1. Connects the RI10 to a SimNet or NMEA2000 network to allow heading and position infor-

mation to be sent to the scanner for MARPA calculations

2. Main data network interface between the radar and the display (ethernet)

3. Provides data and power connection between the Broadband radar dome and the RI10.

4. Power cable (see “Connect power” on page 18)

5. Green LED indicates power is supplied to the RI10 and indicates SimNet state. A sequence

of three rapid  ashes indicates no SimNet connection was made at time of power up and a

solid light means SimNet connection was lost after power up

 Note: Lowrance HDS units sold in the USA do not require an interface box and the scanner

connects directly to the display or Ethernet switch. If chart overlay or MARPA are required for

Lowrance HDS USA then an RI10 Interface box and heading sensor are required

Adding MARPA and / or Chart Overlay

To add MARPA and/or Chart overlay, it is essential to use a heading sensor with an output speed

of 10 Hz. The Heading sensor needs to be a rate gyro stabilized compass or better

You can use a Heading Sensor with an NMEA 0183 or NMEA2000 output source

You must use a Radar Interface box to connect the heading data to the radar system - this is

because MARPA calculations are done by the radar:

• If your heading source is NMEA0183, use an RI11 Interface box for Simrad NX installations,

or an RI10 Interface box with an AT10HD converter for all other installations. The AT10HD

converts NMEA0183 to SimNet / NMEA2000 (only heading information is converted)

• If your heading source is NMEA2000 or SIMNET use an RI10 Interface box.
