[TG] [TG11] Axiom 9RV / RV100 / Airmar UDST800 - data source management

[Mike_EE]

Hi -

I've purchased an Axiom 9RV / RV100 combo and have started installing it into my boat. I'm considering the purchase of an Airmar USDT800 (the new no-wheel depth/speed/temp NMEA2000 transducer) and I'm seeking configuration clarification.

The Lighthouse 3 version 3.5 advanced manual's "Data sources menu" section seems to indicate that I can manually select the source of speed through water and depth; sourcing of temperature is less clear in the illustration. The forum thread FAQ "Sonar Prioritization with Multiple Data Sources (LH3 R1 and onward)" (http://forum.raymarine.com/showthread.php?tid=5357) muddies this somewhat by stating that depth, speed and temperature are prioritized automatically and, in the abscense of being able to use the above sensor for experimentation, it's not clear to me if I can aribitrarily select the data sources for the D/S/T values from the USDT800.

Can someone please clarify?

Thanks,

Mike
