PMDG737 NGX module 4.3 - MCP1 Knobs

[ScotFlieger 280]

Original Post from F.Skywalker (moved to LINDA Support)

 

Hi Scotflieger,

 

thanks for the update.

 

I use the MCP1.(orig)

After this Update the CRS Knob ist only working on the left side. The right side do not work.

 

my Linda Version  (3.4) PMDG NGX  works smoother.

The syncronisation ist very fast.(3.4)

 

In 4.3 when you turn the HDG, ALT, SPD fast it is not syncron whith the Display.

You must make very time a little korrection.

 

CRS work only left, if you press right the diplay says right without work.

 

Sory about my bad englisch.

 

Frank

Hi Frank 

 

Thank you for reporting the issue with the latest module 4.3 with MCP1. I have reproduced your question here for answering your support question.

 

I have compared the code between versions 4.3 and 3.4. Apart from the readability changes, the code for HDG, ALT and SPD are identical and there should not be any difference between the response on your MCP1 (or other panels). I did find the _incfast and _decfast functions too vigorous (changed too fast) and changed the repeat count from 4 to 3. Can you try editing your copy of version 4.3 as follows:

 

In SPD, HDG, ALT _incfast and _decfast functions change: 

        for i = 1, 3 do ipc.control(PMDGBaseVar+???, PMDG_???) end

to:

        for i = 1, 4 do ipc.control(PMDGBaseVar+???, PMDG_???) end

 

The CRS R (FO's course selector) operation will be fixed in the next update.

Hi Scotflieger,

 

where must i make the editing.

Open the PMDG737 actions.lua file (in /fsx/modules/linda/aircrafts/pmdg737ngx/) in the LINDA editor.  There will 6 such entries (2 for each control).

Hello togehter,

exactly same situation here:   MCP1  v3.4 ok,  v4.3 toggle-functions struggle, i.e.  crslr-toggle or light-toggle and so on.

Glad, this can be resolved in an update.

LINDA is such a beautyful thing to handle my small cockpit and I want to say thankyou once again to Artem, Guenter, Scotflieger and all the other contributors for such a handy tool.

 

Gruss, Wolfgang

Thank Wolfgang. I believe I have a fix for Frank's reported problems (SPD/HDG/ALT) and CRS R. I am not sure what you mean by the NGX_CRS_LR_toggle and NGX_LIGHTS_toggle struggling. Note the NGX_LIGHTS_toggle function is now in uppercase.

 

Your appreciation makes our work more rewarding.

Hi Scotflieger,

 

the Change 3 to 4 is the same.

It is hard to write about a Problem.

In Version 3.4 when i turn SPD,CRS,ALT, it was allway sync the nummbers on the mcp and the ngx sync in the same time.

In Version 4.3  is not syncron.

HI Frank

 

I have a fix available (adding extra sleep time in functions). However, I am concerned about Wolfgang's observations and will delay an update until I hear from him.

Ok, thanks.

Hello Scotflieger this is Wolfgang again with following obsevations:

 

1.

-NGX Lights Test toggle-  brings up the following error-code: 

[E] *** LUA Error: ...\FSX\modules\linda/aircrafts/PMDG 737NGX/actions.lua:5992: attempt to call global 'NGX_LIGHTS_Bright' (a nil value)

So tried it with -NGX Lights cycle- and voila, that gave me the wished result I had before with Lights Test toggle in v3.4.  I now can the test turn on and off.   So I confused  toggle with cycle.

 

2.

-NGX AP CRS LR  toggle-  in v3.4 let me operate both course-knobs in the VC.  This isn t he case in v4.3, nothing happens, same with CRS LR sync, but no error-code shows up.

 

Hope this may help.

 

Gruss, Wolfgang

Hi Wolfgang

 

What MCP are you using?

[wokue 2]

hi Scotflieger,

as stated above MCP 1 (the first of the series). LINDA version is 2.6.7

Hi Wolfgang

 

Problem 1 is a typo in the code. The function should read NGX_LIGHTS_bright (not _Bright).

 

Problem 2 is more complicated. My inspection of the code between 3.4 and 4.3 shows no structural or logic differences.

 

For the MCP2 and MCP2a panels, the NGX_AP_CRS_LR_ functions work depending on the DME selected on the Radio panel and changed using NGX_AP_CRS_LR_sync. DME1 outputs to the Capt's CRS and DME2 to the FO's. For this to work, you need to assign NGX_AP_CRS_sync to the DME Select 1 and Select 2. Then pressing the DME button will change the DME between 1 and 2 and swap (sync) the NGX_AP_CRS_LR_ functions to the selected DME: 1 for left and 2 for right. 

 

For the MCP1, selecting NGX_AP_CRS_LR_toggle will swap the CRS output from the left to right and vice versa. The NGX_AP_CRS_LR_sync changes this behaviour to match the MCP Combo 2 Boeing and Airbus panels (MCP2 and MCP2a).

 

The NGX_AP_CRS_LR_ functions work with EITHER the Capt's OR the FO's CRS display NOT both.

 

Thank you reporting the issues. I can test as much as I want but I only have the MCP2 and MCP2a panels, not the original MCP1. I will issue an update to the module (4.4).

Dear Scotflfieger,

thanks to your efforts in v4.4 the issues even with MCP1 seems to be solved.

 

Have a good time and cheers, Wolfgang

[ScotFlieger 280]

You are very welcome. I am pleased that I have solved the issues with the MCP1 panels.

[majapahit 3]

have a MCP1 also,

can confirm all above, all is fixed & No more settings lags (had me worried there for a while

 

//

here, there was a long post about my trial and error about my MCP1 A/T_ARM switch not working,

but, all-in-all I now can make it work with “NGX AP ATHR toggle” instead of "on" and "off"

//

 

by the way, "all taxi toggle" and "all landing lights toggle" that's a treat

 

 

 

EDIT2:

 

when from LINDA, I set either (or both !?) MPC1 A/T_ARM switch positions to

“NGX AP ATHR toggle”,

this makes the switch work

 

so it seems, at least in my download(s), that “NGX AO ATHR arm” and “off” don’t work?
