Without connecting the plotter to a computer or device and monitoring the output it's hard to know for sure which NMEA sentence prefixes it is sending.. As others have mentioned, if the sentences are
GPGLL or similar, the Icom 411 will accept those messages. If they are
ECGLL, etc.. then the Icom will ignore them.
However, you first need to make sure that HDS5 is setup properly.
HDS5 Installation Manual - Page 30
Icom ic-M411 User Manual - Page 42
1.) Pick one of the two
ports to use for this (port 1 or port 2) for HDS... Looks like HDS5 units only have 1 port)
2.) Identify the positive and negative TX/Output wire on the Gen5 that corresponds to that port, and make sure they are wired to the corresponding RX/Input wires on the 411.
HDS5 - (On the power/data cable)
TX+ = Yellow
TX- = Blue
IC-M411 - (The wire on back of
radio without a connector)
RX+ = Center Wire
RX- = Outer Shield
HDS5 User Manual - Page 107
3.) Set the HDS5 Port to NMEA or RS422 (not RS232)
4.) Set the HDS5 port to 4800 Speed (NOT 38400)
HDS5 User Manual - page 108
5.) Enable the GLL and GGA sentences to be output (Page 108 of the User manual) Note: HDS5 does not seem to support RMC and GNS (per
Installation Guide)
Assuming you've done all of the above, and verified the settings.. If it doesn't
work, it's likely that the issue is the NMEA0183 sentences are being "bridged" or converted from NMEA2000 inside the HDS5, and the prefix is not GP. If you have any other source of GPS, you may be better off trying to get the data directly from the other device (such as an
AIS Transponder if you have one, but of course there may be configuration complexities there too.)
