Icom M323 to Garmin NNEA 2000

Hi I have a garmin NNEA 2000 network on my Rib, after 3 Garmin VHFs have broken I decided to buy an Icom M323. Now getting a bit confused with how to wire up the data, to get the most out of the VHF

My Icom has 4 wires
Brown - Talker B (Data-L)
White - Talker A (Data-H)
Green - Listener B (Data-L)
Yellow - Listener A (Data-H)

My Garmin NNEA 2000 Network has a 5 core cable as follows
Pin 1 = Shield
Pin 2 = Red (NETS +ve)
Pin 3 = Black (NETC ground)
Pin 4 = White (NETH High Signal)
Pin 5 = Blue (NETL Low Signal)

On the garmin network I have a 5008 Chartplotter, AIS600, Fuel Guage & Depth sounder

Can anyone help with the best way to wire up the network

The Icom 323 isn't nmea2000, only nmea0183. You will have to use the nmea0183 input on your plotter.

Sh1t happens
