737NG overhead

[garyk007]

I have a question about the 737NG overhead.<O:p</O:p
I know some of the annunciators have 1 state and others 2 states.
SO you would have 2 independent leds in the ones with 2 states right. And 1 or 2 leds wired together in the single state annunciators.<O:p</O:p
<O:p</O:p

But the question is which annunciators are single and which are dual?<O:p</O:p
<O:p</O:p

I have the colour chart in gif format of the 737 overhead but don’t know which are which.
<O:p</O:p

Also does anyone out there know how many inputs and outputs are required to wire up the over head panels?
<O:p</O:p

Thanks

Hmm.. Looks like a smile bomb went off!! :) Most of the Blue ones are dual state. They are bright while the valve is in transit and dim when set. What are you using for an interface?

[garyk007]

Open cockpits IO cards.
Are there any that are not blue?

Should the single state have one or 2 leds?

Cheers

I'm using FSBUS Classic. I have two independend Led. One (for transition) bright and one (for on) dim. Look nice and work fine.

I have only 9 two state blue annunciators. 2 in Engine valves, 2 in Spar Valves, cross feed, 2 wing anty ice and 2 cowl valve.

Best regards Marek

To the best of my knowledge ( no expert) this list sounds right.

I am working on an excel spreadsheet, which will contain every input and output in the 737NG cockpit.
I will post it when I am done.

My cousin is flying a 737-600 so I will get him to take the lists to work and check them.

He has a really cool office by the way. The view out his window changes every day.8)

Thanks all
