Up- or downgrade?

[aegean seagull]

Hi folks,

I have a NMEA 2000 network setup on my boat with a DF300 mod 2009 interface, a 4" Suzuki SMIS, a Garmin GMI-20 and several fluid level sensors linked to it. The system runs fine, all engine and fuel/water data properly displayed at the MFD and the SMIS gauge.

I recently tried to add a second 4" Suzuki SMIS to the network, but on power-on I got a couple of error messages about "keyless battery low" or something like that. The warnings were displayed on the new gauge only, and a "check engine" message is permanantly on display. The S/W version of the new SMIS is 2.6.0, but the old one is running on 2.5.0.

So, the question is: do I upgrade the old one to 2.6.0 or downgrade the new one to 2.5.0? If I upgrade the old one to 2.6.0, how do I set off the error message (which I assume that will be displayed on both gauges once the old one is on the 2.6.0 version)?

I would downgrade the new one to 2.5.0. Logic being that if the existing one was working fine with your motor then set the new one the same and it should be fine too.

I agree with your logic.

I googled the update file, but can't find it. The link in the thread you started last year is downloading the 2.5.0 S/W update for the eng interface and not the 4" gauge.Would you please update the link?

I did the same on my DF100A - downgraded.
Got the same errors with 2.6.0 and everything was ok when downgrading to 2.5.0.
