NMEA input to a78 MFD

Charlie,

As indicated within my prior response, Actisense offers different versions of the NGW-1. If you review the list of NMEA 0183 sentences supported by the NGW-1-ISO, you will find that this list does not include support for any NMEA 0183 AIS sentence identifiers (VDO, VDM, and ALR). NGW-1-ISO-AIS is the NMEA 0183 AIS option. This is a pre-configured version of the standard NGW-1-ISO that enables the conversion of NMEA 0183 AIS data to its equivalent in NMEA 2000. This provides an 'out of the box' solution for quick installation with no configuration required. Please see the list of NMEA 0183 sentences supported by the NGW-1-ISO-AIS to view which AIS conversions the NGW-1-ISO-AIS can perform.

Accordingly, you may want to consider returning the NGW-1-ISO to have it replaced with a NGW-1-ISO-AIS. Alternatively, you may want to consider contacting Actisense Support for instructions and software to reprogram your NGW-1-ISO to perform as a NGW-1-ISO-AIS.

With respect to configuration of the MFD's NMEA 0183 port, you are not connecting the Standard Horizon GX2200 to a MFD's NMEA 0183 port. You have instead interfaced the Standard Horizon GX2200 to a NMEA 0183 to NMEA 2000 data bridging device. Accordingly, the excerpt within your Standard Horizon GX2200's manual does not apply. The instructions provided within the 38400 BAUD Connections page of Section 6.5.2 of the GX2200's manual (see page 21) apply to how the GX2200 would be interfaced to the NGW-1-ISO-AIS.
