I need to send a multi-page NMEA message (26 bytes) from a PV750 onto a NMEA network. What is the best way to go about doing this? Thanks for your help.

Re: Transmitting a multi-page message
Will,
The default method of transmitting multi-frame parameter groups in NMEA 2000 is using the Fast Packet protocol.
Look in the Database and you'll see a Fast Packet column in the J1939/NMEA parameters. Check that box on the your newly defined PGN and then map the 26 bytes into the parameter(s) in the window below. The sequence and frame counters are taken care of for you.

Re: Transmitting a multi-page message
The issue is that none of the fast packet messages are selectable in the transmitter, only J1939 and 8 byte NMEA.

Hi WillM, mbowdich,
The ability to transmit fast packets or multipackets is not currently supported. This post will be moved to the Request Features discussion. Is it possible to break up the data into single packets?
Thanks,

Re: Transmitting a multi-page message
Probably not in NMEA, as most of the pertinant engine data is Fast Packet. They could be hand generated (FFCAN), but would require some detailed knowledge of the structure to write.
