8 Digital Radome Scanner - User Guide Planning the installation 12.5° 12.5° D11359-1 Mount the scanner so that the array rotates parallel to the waterline. The radar beam is approximately 25o wide in the vertical direction, giving good target detection when your boat pitches and rolls. D11358-1 Mount the scanner as high as possible above the waterline for better long range performance, but make sure it: • • • • • is above head height. is easily accessible.
Installation 9 Cable requirements Digital cable You must consider the following points before installing the system cables: A digital cable, illustrated below, is required. This provides both power and SeaTalkhs signals to the Digital Radome scanner. It is fitted with a SeaTalkhs plug, and power cores for connecting to the scanner. • • • • • You need to connect the scanner to the multi-function display unit and power (and, if appropriate, via a SeaTalkhs switch).
10 Digital Radome Scanner - User Guide Power cables Digital Radome radar systems are intended for use on boat’s DC power systems operating in the range 12 to 24 V DC. The Digital Radome scanners should not be used on nominal 32 V systems. If you are replacing an existing (Analog) Radome scanner with a Digital Radome scanner, you must replace the existing cable with a digital cable, as described on page 9.
Installation Connecting the power and digital cables 11 Digital Radome connected directly to C-Series display The following must be observed: • The threads of the Digital Radome digital cable external connector should be lightly greased with “Renolit Aqua 2 Calcium” grease if disconnected after the initial installation. • Preferred connection of the power cable is directly to your boat’s power distribution panel.
