[CA] [CA11] System upgrade

[rickgiles]

I am in the process of upgrading a 10 year old system that used the previously referenced radome, the system had a E80 chart plotter, Daisy chained ST 60 wind, depth, and speed instruments a Raymarine auto pilot along with a AIS 500. it was networked together with an Actisense NMEA0183 Data Multiplexor and a Raymarine NMEA0183 Multiplexer. It also has what appears to be two externally mounted RayStar130 GPS Receivers my guess is that one may be part of the AIS system. The boat was recently imported from Canada and the AIS was broadcasting the wrong information (boat was .21 miles long and 200 feet wide) so it's in for reprogramming to my new MMSI number, vessel name, contact information and corrected boat dimensions. The current VHF is an icom unit that is not hooked up and so the DSC function is not operational.

My replacement system is using a Raytalk ng backbone, some 5 way connectors. An Axiom Pro 12-S plotter, several I-70 instruments, a Quantum 2 Doppler radome, an Evolution auto pilot I would like to retain the ST60 instruments, the AIS500 and icom VHF. I have added a Raymarine SeaTalk1 to SeaTalkng converter kit. So far everything is taking to each other except the AIS which is still networked through the existing Raytalk1 system, targets showed up on the E80 but do not on the Axiom Pro. The auto pilot is on backorder from Westmarine, once it arrives I'll add it and the AIS to the ng backbone.

Three questions;
1. after that can I ditch the existing Actisense NMEA0183 Data Multiplexor and a Raymarine NMEA0183 or should I connect the icom to the 0813 network and keep the Multiplexer's?
2. How do I wire the VHF so DSC is functional?
3. is the external GPS receiver still necessary?
