MMR's

[jonesm35205]

Hi,

I think I actually asked the original owner of this great panel this before he left but he wasn't really
going to correct it after he said he was leaving. But I did see that another person asked again later
and you asked him what MMR's were. MMR's d are the Multi-Mode Receivers that you can now
use in the Zibo if you turn on that option on the Tablet. I have never been able to use them because
our xsaitekpanels won't work with them, but they look nice to have. So if there's anyway to get those
working with this panel that would be great. A Lot of people would be grateful.

Thanks,
Mark

What are we supposed to do? I cannot find any dataref or command related to MMR in the "B738_Commands" or "B738_Datarefs" of Zibo

[jonesm35205]

Well I guess I'm not understanding why your coming at me with that kind if attitude? All we do on here is ask if its a possibility of adding it since you obviously understand how to work with these types of things. I dont pretend to understsnd it completely. All I really know is in the tablet their is option to use the MMR's instead of the regular ILS radios. No idea how Zibo allows and we can use it if their are no datarefs involved. Just know our panels as they are now wont work with them and as a few said it would nice to use them. I mean in the end if their is 0 chance of doing it and making them work then that takes care of it.

Sorry but my comment was not intended with bad attitude. I was lost trying to guess what MMR really is. Now I've found that is just the panel for switching between ILS, VOR or GLS, which is enabled by default on the Zibo.

I don't have a radio panel, I just have the switch and multipanel, so we need here some collaboration of a programmer who owns one of them. Or maybe someone wants to send me one radio panel as a xmas present? ;)

[daniol]

I think implementing this would be very tricky in this panel.

This panel has:

• A knob for displaying COM 1, COM 2, NAV 1, NAV 2, ADF, DME, XPDR (Squawk code)
• A dial to select the frequency (in 0,01 increments)
• A button switch between active and standby

ILS frequency range: 108.10 - 111.95 MHz
VOR frequency range: 108.0 - 117.95 MHz
GLS range: I don't have any idea, but Zibo let's you enter anything from 2000 up to 9999.

To which knob position would you assign each MMR mode? I guess you can use NAV 1 & NAV 2 for ILS, ADF for VOR and DME for GLS? Obviously you would loose the ability to select ADF or DME, but there is no other way...

Also to be mentioned, that this panel does not support the ability to enter 3 decimals for frequencies.

I'm agree with @daniol and I think that if anyone wants ADF or DME have to choose OLD navigation mode, if anyone wants the new MMR has to loose ADF & DME. In every kinds all have the possibility to choose what they wants.

[jonesm35205]

I do agree. Its the only thing that can be done. Just make one with the MMR's and say in the comments that anyone choosing this gives up the other two items. So two choices with that understanding and take your pick.

At this point I have only a question
considering this case:
ACT : ILS 110.30
STBY: VOR 111.20
If I click on switch button in Zibo cockpit, the system switches between both, but how can I do that with Saiteck switch button? It switches between only same types (ILSs, VORs, etc...). it can't switch between ILS and VOR (if I use rotary selector to select type of frequencies).
another thing: SWITCH MODE button affects only STANDBY frequence not the ACTIVE....

After a very long wait, my Logitech radio panels arrived yesterday.

I tried to set them up with X-Plane and 737-800 Zibo and encountered the issue outlined here.

For those unfamiliar with this aircraft, there are two versions of the NAV radio panel in the cockpit.

The default version uses keypad style buttons to change the ILS frequency and is referred to as the MMR version.

The alternative version is an 'older' type panel which uses a rotary knob to change the ILS frequency.

Users can switch versions by enabling/disabling MMR from within the Electronic Flight Bag (EFB) located inside the cockpit.

The Logitech Radio Panel works fine with the 'Rotary Knob' version i.e. input from the Logitech Panel physically changes the ILS frequency in the aircraft and displays the corresponding frequency on the NAV panel in the cockpit.

However, if the MMR version is present, input from the Logitech Panel physically changes the ILS frequency in the aircraft but does not display the corresponding frequency on the NAV panel in the cockpit.

So, this seems to be associated with the input type i.e. Rotary vs Keypad and hopefully, something which someone with appropriate coding skills may be able to resolve.

@slicker55 : is that the only thing that does not work? What about changing between modes, as pointed by @CyberGuerro ?

In this script there are some datarefs that possibly are currently not set (section "MMR"): https://sky4crew.com/download/b737-800-zibo-squawk-config-for-ivao/ . I don't have a radio panel, but I could try to simulate it and see what happens, if no one else here has the skills for that.

Another solution can be only to allow the mode MMR to be active; that would mean activate it automatically in case MMR is deactivated or showing a warning. Searching in the zibo source code, there is a dataref for that: laminar/B738/fms/mmr.

@daniol

Thank you for taking an interest in the issue outlined.

CyberGuerro, makes a valid point... for full functionality we need a facility to operate the MODE and ACT/STBY buttons in addition to entering a frequency into the STANDBY window.

Forgive me if I'm trying to teach you how to suck eggs - just trying to be helpful...

Here's an image of the MMR version of the Nav panel:

The UP/DOWN (MODE) buttons toggle between ILS / VOR / GLS in the STANDBY window
The keypad is used to input a frequency into the STANDBY window
The ACT/STBY button transfers the frequency set in the STANDBY window to the ACTIVE window and vice-versa.

I hope this information clarifies everything.

Finally, 'allow MMR mode to be active' is a fantastic idea

Please let me know if there is anything else I can do to help.

[daniol]

Our code for the radio panel is currently empty, The handling is done by the default behavior of the base plugin "Xsaitekpanels" (code on sparker256/xsaitekpanels).

I guess we can trigger some action when the input is changed physically and try to refresh the numbers of the MMR but... does it have sense to have the MMR option if you can just set the ILS frequency (not VOR, not GLS)? The older type is better because you can also select a VOR frequency.

Furthermore, I have also some questions:

• Does the ACT/STBY button on the Logitech radio panel work?
• Do the ADF and DME frequency selection work?
• Do the transponder selection work?
• By "it changes the ILS frequency in the aircraft" do you mean the active or standby frequency?
