Network An Ethernet network is used to distribute the radar data to compatible multi-function displays. The RI-12 is connected to the Ethernet network using a standard Simrad Ethernet cable and the supplied adapter cable. The RI-12 can be connected either directly to any Simrad compatible MFD or to a network switch such as an NEP-2 or SonarHub.
NMEA2000 The RI-12 can be connected to a Micro-C NMEA 2000 network to receive heading and position information. A heading sensor is required for the following functionality; • MARPA : heading at 10 Hz or faster is required for the radar to calculate MARPA tracking. Heading must also be connected to the display. • Radar Chart overlay: heading is required by the display to correctly overlay the radar over a chart. • North Up: For the display to show the radar page with the top of the PPI as north.
NMEA 0183 The RI-12 has one NMEA 0183 (RS422) to accept heading and position information. The NMEA 0183 port accepts data at 4,800 baud. Sentences used HDG, HDT, HDM, GGA, GLL, RMC, VTG. Heading should be at a minium of 10 Hz update rate. D NMEA 0183 RX_A NMEA 0183 RX_B f ra t_ RI-12 heading source selection: _A 08 The RI-12 receives heading via the NMEA 2000 network and transmits this data to the radar, where MARPA processing is performed.
When all connections have been made and checked the safety switch on the rear of the pedestal can be set to the ON position Setup and configuration of the Halo® radar has been simplified compared to traditional pulse radars. There is no zero range adjustment (time delay), no warm up time, and no burn in required. f ra D 6 Setup and configuration Source t_ On the radar page, choose the radar to be setup using the source drop down.
Adjust antenna height... Set the radar scanner height. Use the slider control or the “+” or “-” buttons to set the value then SAVE. Note: It is very important to set the antenna height configured correctly as this will affect the sea clutter function. Do not set the height to 0. f ra D t_ Adjust bearing alignment... 15 20 il_ pr _A 08 Adjust the heading marker.
Sector blanking On vessels where the radar is installed in close proximity to a mast or structure that could cause unwanted reflections or interference to appear on the radar image. Use the sector blanking feature to stop the radar from transmitting in the direction up to four sectors. Note: Sectors are setup relative to the heading line of the radar. The bearing of the sector is measured from the front of the vessel to the center line of the sector.
1. 2. 3. 4. 5. 6. Set radar range to between 1/2 nm to 1 nm and Sidelobe Suppression to Auto Take the vessel to a location where sidelobe returns are likely to be seen. Typically this would be near a large ship, container port, or metal bridge Traverse the area until the strongest sidelobe returns are seen Change Auto sidelobe suppression to OFF then select and adjust the sidelobe suppression control until the sidelobe returns are just eliminated.
Control pedestal accent lighting The Halo™ Pulse Compression Radar pedestal has a blue accent light. The L.E.D. accent light has four light levels controlled from the radar menu. Note: The accent light can only be adjusted when the radar is in standby Halo™ Pulse Compression Radar’s blue 4 level static accent pedestal lighting may not be approved for use in your boating location. Please check your local boating regulations before turning the blue accent lights ON.
