It takes traffic from one RS-232 port and spreads it out to 2 or more RS-232 ports.=C2- If you have fast traffic, it will spoil your day if you try to divide that fast traffic port into 2 or more ports.=C2- Some ports want to see fast traffic with minim um latency (delay). Ask Garmin if they make one or better yet, consult with one of their technicians to see if the Expander is compatible with their t raffic flow.=C2- I know GRT makes an Expander and works well with their t raffic flow. I'm still trying to figure out why RS-232 is being used in experimental air plane applications.=C2- They should have gone with RS-422 a long time ago to avoid signal compatibility and integrity issues.

In total it quit 4 times, the longest for almost 4 minutes. After landing we wiggled all the wires, checked several for continuity, everything looks good. We have no cooling air going to the alternator at the back of the engine and it was a warm day and the engine compartment was very hot. Is it possible this is a heat problem or definitely wiring / regulator / alternator? Thank you, Sebastien ________________________________ Message 4 _____________________________________ Time: 06:30:53 PM PST US Subject: AeroElectric-List: Re: Alternator Dropping Off Line From: "user9253" Not enough information is given. How many hours on the alternator? 13.8 volts is low. One possibility is worn brushes. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=490233#490233 ________________________________ Message 5 _____________________________________ Time: 10:13:46 PM PST US From: Sebastien Subject: Re: AeroElectric-List: Re: Alternator Dropping Off Line That 13.8 is at the start of a failure cycle. Normal bus voltage has been 14.1 on the last several flights. The engine was recently overhauled, I'm trying to find out if the alternator was as well. It *looks* new.
