DCS interface to MFD

[Pdog1989]

I have a Ray 240 installed and eSeries MFD's....I read in the manual that upon a DCS notification, it would highlite on the MFD and then you can goto vessel etc.
I wired the Ray 240 via NMEA 0183 to the MFD as the Ray 240 doesn't have NMEA2000 compatibility.

For some reason, it won't work and have tried everything over the last couple of years....are there particular settings I should validate on the MFD--i.e. BAUD rate on the input to MFD etc? Will the DCS interface not work with NMEA 0183 connections?
