MGL Avionics User Forum

Hi everyone,
I'm trying to get one of the outputs from iBox's "Encoder/MISC Connector" to ground a small LED in my annunciator once autopilot is activated but cannot see any option for that. In the manual it states that -

"O1,O2,O3,O4 These four outputs are open collector darlington transistors capable of sinking
500mA of current each. The function of these outputs is determined by the EFIS panel. For
MGL EFIS panels you can create a “script file” that will switch these outputs depending on
defined conditions."

I haven't found any info on how to create or upload the above mentioned "script file". Anybody can help me with that?

Thanks and Happy New Year,

Paul

I guess nobody knows about the "script file" so I have address the issue directly to Rainier - can you help me to found anything about how to write such a code or get any info that will help with that.
Thanks,
Paul

There used to be a script file you could create for older EFIS systems.
For iEFIS this has not been included - rather there is a menu system where you can assign functions to outputs. This is under system setup. Autopilot status is not one of the options. The outputs are mostly used for alarms.
However I'll add a autopilot status option for you with next update.

I've installed the latest firmware but didn't find the A/P option in the menu. Any chance to add it in the later revisions?

System Setup -> Digital Outputs setup -> Select desired output - > set to "Autopilot Engaged"

I have G3 with Version 1.1.2.8 installed but didn't see that option in the Digital Outputs section.

Hello
Try "Digital inputs setup"

I did, just didn't use the whole "Digital Output Setup" name in the previous reply. I've tried the latest G4 simulator and the Autopilot engaged option is in there but not in the G3 firmware.

I have added it to the G3 now - download the files from current link in the Firmware page. Version is now "B" 1.1.2.8
It has been added to G4 prior.

Thank you Rainier, I really appreciate it.
