[CA] Basci question re: i50/i60 wiring

[slavanway]

I am upgrading to an i50/i60 depth, speed, wind package, a Quantum chirp radar, and Axiom MFD at the nav station and helm. I plan on using the 'Basic Seatalk Retrofit' diagram that I find here
http://api.ning.com/files/rRUWEC*XQHwlVF...trofit.pdf

Two questions, I can't find a definitive answer for.

1. If I connect the transducers to the i50 and i60 displays and then connect them to an ng backbone dows the depth, speed, and wind repeat on the ng backbone so I can see the data on the MFDs and the Evo autopilot.

2. Can the Axiom act as a datamaster (like the i70) if I wanted to go 100% ng backbone and use an ITC or do I still need an i70 some place.

TIA for any help,

Sam
