RE: [CA11] Electronic Upgrades for our Manta 40 Catamaran

Your system diagram now appears to be correct regard to how the equipment should be interfaced and how the backbone should be powered. As you have suggested the MFD must be powered via the Power cable which is supplied with it. Similarly, the Quantum 2 Radome must be powered via the supplied Quantum Power Cable or via a Digital Radar Cable (the latter would be recommended for those seeking a wired communications path to the Quantum 2 radome. Finally, the ACU will need to be powered. Please click here to view a FAQ addressing installing power circuits for marine electronics.

Q1. can I use my older GPS antenna with the Axiom Pro or does that require a new antenna?
A1. Yes. The Raystar 125 GPS Sensor may be interfaced to the system in either of the following ways without incurring additional hardware:
- interface it to the SeaTalk bus to which the ST60 instruments and Smart Controller base station have been interfaced, or
- interface it to the NMEA 0183 Port 1 leads of the MFD's Power/NMEA 0183/Video Input Cable. This method will require that the Raystar 125 GPS Sensor be powered from a switched 12VDC power circuit.

Q2. Is the Airmar P79S Smartâ„¢ In-Hull Transducer a good choice for our sailboat or are there other depth transducers you would recommend?
A2. Maximum depth performance will generally be achieved with depth transducer which is in direct contact with the water. However should the instrument's primary function be to monitor depth in shallow waters to keep the boat from grounding, then an in-hull transducer such as the P79S should be satisfactory.
