An adapter cable must be used if the Halo Radar is to be connected using a pre-existing Broadband radar interconnection cable. Before taking scanner up mast/pedestal: 1. Insert the connector of the adapter cable (A) into the scanner socket. Turn the locking collar to secure the connector. 2. Install the first retainer across the adapter cable using the supplied screws. Tighten gently. 3. Install the second retainer using one screw only, leaving it turned to one side so the cable channel is left open. At mounting location: 4. Insert the connector of the existing interconnection cable (B) into the socket on the adapter cable. Turn the locking collar to secure the connector. 5. Swivel the second retainer over cable and gently tighten both screws. A B RI-10 Radar interface box and wiring It is recommended to remove the RI-10 Radar interface box. After removing the RI-10 Radar interface box, reterminate the connector. Use the appropriate tools to strip the 4G cable about 20 cm to allow the waterproof cable boot to slide over the RJ45 connector. Refer to "Waterproof cable boot" on page 17. Connect the 4G cable wires to power as described in "Power connection" on page 18 and "Power control connection" on page 19. If removing the RI-10 Radar interface box and associated cables/wiring is difficult they may remain in place when a Halo 20/20+ or Halo24 is connected via the scanner adaptor cable, with no detriment to performance. Check the Fuse/circuit breaker rating is as specified. Refer to "Technical specifications" on page 27. ¼ Note: Halo dome radars do not require navigation data via Simnet or NMEA 2000 for MARPA or Velocity Track to operate. 22 | Replacing a Broadband 3G/4G Radar | Halo20, 20+ and 24 Dome Radars Installation Manual
