Software to write to PCMCIA datacards?
I'd like to update the database for my Apollo GX55 GPS. $120 for the
raw data is bad enough, but Jeppesen also wants $150 for a writer. The datacard is a PCMCIA card, so wouldn't it be possible to work with it with a plain old laptop or a $10 reader from Best Buy? I'm wondering if someone has found a way to do this. -- |

The problem is that the data on the card is not in an open file format. So,
you need Jepp's application to do the writing. Jepp's application is designed to interface with their writer. This is not necessary but is the way it is designed. The alternative would be software drivers installed that know how to deal with the format of the card and can negotiate with other installed drivers to take over when appropriate - not an easy thing to control. Until they are willing to change their application, we're stuck with using their writer. -- ------------------------------- Travis Lake N3094P PWK "Charles" wrote in message news4Oji.18991$Fc.10534@attbi_s21...

... so that the PC software can write to it in a simple manner. I don't know what is involved but can tell you that if you plug one of these into a normal reader and invoke the windoze API call for reading physical sectors, all you see is rubbish; mostly zeroes. It looks like they are using some odd property of the flash chips, but that would lead to rapid obsolescence. No odd property of the flash chip at all. Just a low level data structure that makes no sense to the Windows drivers trying to interpret it as a device that supports a filesystem. It is entirely feasible to write a Windows driver for a Jepp datacard. You would bypass all of the Windows drivers and be writing a very low level device interface. I'm just glad they still support data updates at all. Pay the $150 and enjoy the updated data in your GX55. ------------------------------- Travis Lake N3094P PWK |

The GNS 480 and the MX 20 use a standard windows CF
reader (which they give you a sandisk one with the units). The cards have a serial number hidden in one of the FS fields, but otherwise are standard. JSUM pretty much doesn't care what hardware device you use to program it as it uses the standard windows filesystem calls to access it. I've used a PCCARD-CF adapater to program mine. |

Charles, When you asked about this on the Husky list, I didn't know you were trying to duplicate the datacard. Don't know if it helps, but I used a program called Winhex to duplicate the compact flash card for a GNS 480. You might check and see if it fits the bill. http://www.x-ways.net/winhex/ - Don And let's get one thing straight. There's a big difference between a pilot and an aviator.

Do a search for Raw write/read you can clone the flash drives including

I'm just glad they still support data updates at all. Pay the $150 and enjoy the updated data in your GX55. No matter what the filing system is, one should still be able to read *logical sectors* from a CF using any cheap CF reader. AFAIK the reader just returns logical sectors - the file structure is down to the O/S. If you read a KLN94 CF cartridge (an old 48MB Sandisk part; they must have bought loads of them) in this way, you get mostly zeroes, plus a very small amount of rubbish which doesn't seem to be valid data and there is nowhere near enough of it for the size of the database (about 2MB). Hence my comment that they are invoking some flash chip feature. |

It's used to clone GPS data cards and other type of media. Helps Recover
