[CA11] Axiom Speed Issue - Amm13421 - 02-26-19 07:47 PM

I am having a problem with a newly installed Axiom 9 RV. It is showing 0 MPH for SOG on all screens. It has software version 3.8.105. I talked to Mark in support today and he had me do a factory reset which I did but that didn't fix the issue. Unfortunately I didn't have the best reception and got disconnected before we could troubleshoot further. I have GPS fix and the boat is showing properly on the chart, but no SOG data...

Thanks for any help,

Welcome to the Raymarine Forum Adam,

Please indicate the makes/models of any other marine electronics devices which have been interfaced to the Axiom MFD.

I have a EV-150 autopilot, it’s also connected to my Yamaha engine via NMEA2000 adapter, and a NMEA0183 to Seatalk NG adapter that is connected to my VHF and my Yamaha command link gauges.

I suspect that the problem may be linked to the engine interfaced. Please specify the make / model of engine gateway which has been installed within your system.

It's just an interface cable that hooks into the yamaha bus, then to a NMEA2000 to Seatalk NG convertor cable.

Yamaha Command Link to NMEA2000 Adapter Cable:

The command link hub should not be interfaced to the marine electronics backbone in the manner which you have indicated. You may verify whether this is the source of the reported issue by switching the electronics OFF, unplugging the engine from the marine electronics backbone, switching the marine electronics ON, and then having the vessel get underway under power. I strongly suspect the you will find that the SOG data item will then be populated as long as the vessel is moving.

Raymarine recommends that the ECI-100 Engine Gateway be used to interface Yamaha engine systems featuring Command Link to a marine electronics backbone featuring Raymarine products.

Will that work with command link only? It says for command link plus but I don't have digital controls.

Should you read the Engine Compatibility information for the ECI-100, you will find that it is supported for Command Link as well as Command Link Plus and the Yamaha engines listed.

The issue was related to my connection to the Yamaha Bus. I have ordered an ECI-100 which should solve the problem.

You're welcome.
