Transducer compatability

[kloshe]

Good morning

Can I connect an Airmar B744V into new a9 MFD.
Current displays are 2002, L1250 connects to RL80CRC.
My understanding is sounder module in RL80 is broke. Plotters, radar, log all function normally on both displays, just no sounder.

I have many questions, so thank you in advance!

Can I connect an a9 with digital sounder to my Airmar ducer.
Can I disconnect current L1250 from RL80 and replace broke sounder with new a9
with in my dash console.
Should I connect a9 to current platform or have stand alone plotter, gps and sounder for redundancy.

cheers, johnny
