IRS Alignment

[jeehell]

Hi Barry,

For the IRS rotating switches, you currently need to have two inputs per switch. One input for the OFF position and one for the ATT position. This is the minimum number of inputs which allows to map all three positions (OFF NAV ATT).

The logic, for all toggle switches, is the following:
- 2 positions toggles: the electrical ON state corresponds to the toggle ON position (or similar). The electrical OFF is the OFF position..
- 3 positions toggles : one input is used for each extreme positions. The electrical ON corresponds to the position where the contact is made. The electrical OFF corresponds to the middle position.

If I read you correctly, you only wired the NAV position on your overhead, disregarding the ATT position (very rarely used) and the OFF position, which was mapped to the NAV electrical OFF in FDS legacy application.
This is currently not supported by my software, and will require a rather major rewrite of the FDS interface (which is more or less planned... but i really lack time these days...).

Regards
JL

Thanks for your comments. I have hit a road block here as I do not have spare capacity for more switch inputs without a major rebuild. Everything went smoothly getting the Simboards out and the Interfaceit in while using AST. I have changed the FCU to Skalarki which has been successful as the old FDS one would not work with your software. I can understand that you do not want to do more work on the software so I have to look for other solutions.
Is there a way I can use Interfaceit with your software I wonder as it accepts my switch setups?

If I remember well, you can run interfaceit application as long as on the same computer you do not run hardware connect, because the way the USB link works (if I remember right) is that the first app laucnhed takes ownership of all FDS/tekworx boards and the next app does not see them as available. I might be wrong and testing is required.

My hardware on that computer is only the Interfaceit boards so I will test and report back.
Thanks again for the help.

Tested but limited results. The Interfaceit software works on "standard" offsets typically on the MIP. The overhead uses "custom" offsets so a lot of work would be required unless FDS can publish an .xml file for Jeehell similar to the ones they put out for other software producers. I guess they would not write it themselves leaving it probably to a user to generate it.
