Hi Again,

My airplane is a velocity with retractable landing gear and I would like the Skyview system to monitor the position of the landing gear in addition to (or parallel to) the kit manufacturers landing gear indicating system... meaning the kit manufacturers landing gear operation and indication system is an intrical unit with two LEDs that will show green when the landing gear is down and locked and I want the sky view to simply show on the screen a green dot for the respective landing gear leg and also enjoy the benefits of the overspeed and gear check functions

I have tapped into the kit manufacturers wiring system wire that is cold when the respective gear leg is not down and locked but it becomes 12-volts hot when the respective landing gear leg is down and locked and wired that to pin 11 for the main gear and pin 12 for the nose gear.

I have set up the EMS sensor input mapping to be function contact, sensor contact, name gear . I have also gone in to the aircraft information and set up landing gear type retract, landing gear check speed 105, landing gear overspeed 120, however the dots on my screen are not changing colors.

In the gear contact configuration volts menu I have selected alarm self clear, maximum graphical display 30.0 volts, minimum graphical display 0.0 volts, range one enable yes, name down, color green, top 30.0 volts, bottom 5.0 volts. Range to enable yes, name nothing, color black, top 5.0 volts, bottom 0.0 volts

So I would have thought that the. Would be green when range one sees V 230 volts and it would become black when the voltage was less than 5.0 volts. I am now getting a warning gear contact low

Can anybody tell me if I am missing something in my sensor contact configuration setup? Many thanks!

I think I figured it out! Range 5 was set to enable and therefore it did not make any change however now it seems to be working as expected

Regarding the nose gear down contact, is there a reason why this cannot also be called gear and also benefit from the not down warning indication in the Skyview system?

The SV only sees 0-5V. So 30V is read as 5V. The contacts are normally measured as 0-2.5V as nothing and 2.5-5V as something. I see readings of 4.995 on contacts all the time. With the dividing line at 5V this would read nothing when it should be a positive reading. Maybe change the dividing line from 5V to 2.5V. You can leave the top at 30V but it will never read that high. Savvy Analysis is a good place to see your logs as graphs for debugging even if you are not flying yet.
