Problem with some Aft Overhead switches.[SOLVED]

[CAVENEY747]

I have one USB expansion card with two master cards connected to it. The first master card
controls various functions around the cockpit and the second master card is just for the
Aft Overhead panel with all of the outputs and 18 inputs used. The USB expansion card is
using IDX 31. I can't attach any files as it keeps saying that 'the extension is not allowed' ?

I have e-mailed the B737.ini file to you and a copy of my script.

Change the line in PMDG B737.ini

MASTER=31,4,2,50

to

MASTER=33,4,2,50


also change all your Device 31 to Device 33 in the script you are using

Tried your suggestion - all of the Aft switches stopped working but Aft outputs were still OK !
Is the problem because I am trying to run two different areas of the cockpit i.e MIP on master card 1
and OVD AFT on Master card 2 on the same usb expansion card ? Should I use a separate usb expansion
card for each master card? Although I don't understand why some switches work and some don't in the
current configuration.

You should be able to mix functions ( MIP, OCH-AFT etc) connected to MASTER cards on same EXPANSION card as long as you use the correct Device number in the script.

But, there is some special code in the driver that allows use of only 1 complete script for all users even if they do not have all modules. I believe this special code is causing your issue.

I will look more into this in the next week. I am out travelling this week.

You could also try to revert to your original PMDG B737.ini with an extra MASTER=33,4,1,100 line and your "original" script and still using the new driver.
Try to test if that works.

Ok, I'll try that and report back. Thanks again for your help.

All working now - thank you for your help!
The problem was that when I changed all the Devices from 31 to 33, I was still
using the old driver. When I realised and changed to the new driver it worked perfectly.
I presume that if I add any more master cards to this expansion card I just
continue to set the variables to Device 33 and they should work ?

Thanks again.

Yes, they should and if they don't just report it here and I will have a look.

I mark this topic as solved now
