[CA] AIS 250 Install

[solomon]

Good Evening,

I have aC120 Classic MFD installed on my boat with some newer devices networked to it. I have an EV-100 A/P and a Yamaha Gateway Command Link N2K interfaced to the C120. As it sits right now all electronics and devices work well. I just came across a Raymarine AIS 250 and I would like to add this to the menagerie. I have the Yamaha Gateway connected via a Raymarine A06045 Cable. Is it possible to jump in on this connection from the Gateway going to the network or is there a better method to make the connection to the MFD?

FROM THE AIS 250 Installation Guide:

Both 38.4 kbaud IN/OUT ports are connected to the single
NMEA 0183 port on either a C or E-series multifunctional display
with the connected NMEA port configured to 38400.

I believe the NMEA Port on my MFD is being occupied by the Yamaha Gateway, unfortunately I am a few days away from my boat and documentation to verify exactly how it is configured. I am just trying to get a head start on this before I install.

Thanks for any and all help
Regards
Chris
