NMEA2000 speed sensor

[MarkSF]

Has anyone installed one?

My knotlog is dead, and I just installed a new Lowrance HDS-5m chartplotter with NMEA2000. I thought a good solution would be to fit a new NMEA2000 speed transducer in place of the current one and use the chartplotter to display speed, rather than get a new speed display and analogue sensor.

The current knotlog and transducer are ancient by the way. No hope of repair.

I will "assume" you have the minium network which is the GPS puck and a single 60 ohm termination resistors

To go to a full network you need the speed sensor and a network kit which had two 120 ohm termination resistors

Once you setup the full network it is easy to keep adding stuff as most items come with a tee

Depending on how there doing things this week you may be able to use a soft tee as stacking 4 or 5 rigid tee can be a PITA

The sensors are "smart" but you you generally have to play with the GPS to get it display to your liking and things are NOT 100 % compatible between brands with the plugs being one of the worst offenders

I just looked at the new HDS and the gps receiver seems to be internal with and external option

No at this point I have no network at all apart from the chartplotter. I don't think I need a GPS puck. I'll probably need an NMEA2000 starter kit, won't I?
