Many thanks!

I can’t wait to get back from Cabo to run right to my hangar and star= t playing airplane again.  The beach gets a little old after a while. &= nbsp;Golf at Cabo del Sol and Las Palmias are fine, but Now I can’t wa= it to get home and see if this works!

The data card is a standard SSFDC (Solid State Floppy Disc Card) that was c= ommon in cameras a few years back. It has been tested in sizes ranging from = 8Mb to 64Mb. The Ground Maintenance mode is entered when a system is powered= up and a SSFDC card is present. Due to a hardware change by the processor m= odule supplier some of the late production (last couple hundred)  IDU-1= s (Experimental EFIS Sport) experience a situation where the processor polls= the SSFDC controller before the controller is fully initialized. This cause= s the SSFDC card not to be recognized intermittently.

Inspect the card for damage, dirt or residue. DO NOT attempt to clean the I= DU connector with sandpaper!!!! There is a high probability you will snag a = contact finger and permanently damage the connector.

Insert the SSFDC with the gold contacts facing down (Experimental IDU-1) or= facing up on the certified IDU-III.

Power up the system. If you plan to calibrate the Chelton ADAHRS, Press the= button that grounds the ADAHRS Pin 16 while powering on the system (install= ation specific) to put the ADAHRS in ground mode as well.

If the SSFDC card is not recognized, press the two knobs (left and right) s= imultaneously for at least three seconds until the screen flashes. This will= cause a hot reboot.

If the SSFDC is still not recognized then power down the system and remove = it. You should have a PC with a SSFDC reader to allow transferring update in= formation from the PC to the card. Insert the card and see if it is recogniz= ed by the PC and if you can read and transfer data onto the card. Transfer s= ome files onto and off of the card to exercise the card's controller. SSFDC'= s are flash memory devices and flash has a finite read / write cycle life. S= ometimes a cell in the file allocation table (FAT) dies and the the card nee= ds to reallocate the FAT cells to recover. Reinstall the SSFDC into the IDU = and try again.

If it still doesn't work you can try reformatting the card in the PC (usual= ly doesn't work) or replacing the card. Some camera's have the capability of= reformatting the card. The format type is FAT16.

If you cant find a card then contact me by private email.
