[simpits-tech] CIM programming to FSUIPC Offsets?

I don't know.  I was going from a quick glance at the BI API for analog 
outputs.

Well there are two ways to do it, you give me a formula that I can use to 
create a custom CIM based function for you to call, or you can implement 
the formula yourself in Lua.

It's part of the documentation in FSUIPC and there's also a column that 
shows it.  If you look at the screen shot I posted, look at the "Type" 
column.

Actually that's the code for write.  You won't ever need to deal with that 
though - in fact hand editing the configuration file will only get you 
into trouble unless you know exactly what you're changing and what effect 
it could have.  The configuration files (there are two - one for the 
simulator software configuration and one for the hardware configuration) 
are created and maintained by CIM so you don't have to worry about 
remembering storage codes, etc.

When I get a chance this week I'm going to post a Camtasia movie of the 
application in use so you guys can see what it does.
