all pushing both right and left buttons do is *reboot* the display, the trigger for going to ground maint mode, is simply the SD card being installed in the slot and it being a valid (good) card.

Hi John,

I think you mean push the two dials at the same time while its starting up…this reboots the computer and, I believe, tries to restart from the card or send it to program mode….just from memory.

 

 

I almost hesitate to chime in because I am just now starting to use the Chelton system and also because I am not sure of the information I have that may be useful, but I was having difficulty entering the programming functions of Chelton a couple of months ago when I first started programming the darn things.  I could not get the card to bump the system into the program mode and finally after about an hour of frustration and rereading the directions, I called the guys at Aerotronics who had installed my panel.  My recollection is that they suggested some sort of magic like pushing two particular buttons at once to get the software to trip into the correct mode.  It’s possible this came from my onsite wiring guy rather than Aerotronics.   So obviously, I don’t know the secret handshake even now,  and am not entirely sure who taught it to me, but I do know that it worked and I could then reliably get into the desired mode.

 

You might try calling up Gary Wirrell at Aerotronics or his smart guys to see if they can help.

 

Regards,

John Barrett

 

 

I bought two of the adapters as described on the chelton efis pilots web site.  Neither one of them worked.

I bought new smart media cards on ebay, smallest I could find was 128 mb and so far so good.

Subject: [LML] Re: Chelton SmartMedia Card and setting system limits

The Smart Media cards and Cheltons are notorious for having issues.  Try cleaning the contacts and make sure that the card is in fully, reformat it on a PC and sprinkle holy water on it.  In general it is good to have a few around.  There is a limit on the size so 16 meg is good (forgot what the limit is).  You can still find smart media cards online- ebay and olympus still sells them, but another option is to get an adapter that uses xD cards which are more readily available.  Look through the Chelton list http://www.cheltonefispilots.com.  There is a lot of information about the smart media issue.
