50g

Anybody know why my installer program for the HP50G connectivity software and users guide lets me install the connectivity software, and lets me connect to the calculator, and save a back up file, but it won't let me install the drivers and it won't let me open the back up file using the connect 4X program? How did you set yours up and what is the objective behind the computer interface? It helps you do what?

If you are on a 64 bit system, there are no drivers for it yet.

The only thing the connectivity kit can do that you can't do with an SD card is take screenshots.

I wish I did have a 64 bit system. I have a 32 bit. The interface program works fine but I can't download the driver. It keeps telling me that it failed to install. I can Transer all the folders and objects to the interface and look at them at get screen captures but the drivers themselves won't download. The drivers include the program for opening your back up files. I can save a back up file but can't open it with the connect 4X program because even though it was installed on the computer, the calculator isn't recognizing it. Any ideas? I tried uninstalling and reinstalling it 3-times. The programming is going good though. I finally learned enough to where I can start really learning and enjoying the calculator. I'll probably still bitch about the manuals though...

You have to manually locate the conn4x\usb folder for it to find and correctly install the drivers. Or do you do that and it fails to install?

The disc I got with the calculator installed the connect4X driver and the application program. The XModem Server works and all the calculators directories and programs and objects are displayed on the computer application program. Notepad automatically opens the folders which destroys the formatting present from the calculator. Pasting the text into WORD restores it. Backing up the files works and you end up with a backup file and no program to open it up with, if its even meant to be opened. I haven't tried to create a program in the computer application program yet because I don't understand what the program is for exactly. It would be nice to use a keyboard to create programs and send them directly to the calculator but I haven't the slightest clue how to do this even after reading the help section.

Keep in mind that I've only used an older version of the Conn4x program because I only have a 49g.

That said, Conn4x by itself only transfers files/directories, backs-up/restores, does screen capture and updates the rom. Unless the newer Conn4x is radically different, it shouldn't allow editing. The newer Conn4x is different in that allows the transfers to be done via USB (as I understand) and that is the only 'driver' that should be an issue (the 49g only has a serial interface). If you're already transfering files thru the USB, you should be all set.

The back-up file should not be opened, at least not with Conn4x, but I don't know if other software that came with the 50g will do that. The back-up file is a snapshot of your home directory plus the alarms and maybe the flags (I don't remember). So it's an aggregate file and in binary and was not, originally, meant to be edited (certainly not with Notepad).

Now, you can transfer individual programs (files) from the 50g and edit those. There are 2 icons in Connx4, one that has 1's & 0's and one with ABC. If you use the ABC icon the transfer is in ASCII an you'll be able to then edit the file in Notepad, but set the transfer to "TYPE 3" in the calculator. That's the bare-bones way of doing it and there are much more safisticated ways to create/edit programs on the PC and you may have gotten such software on the CD, but I've never used it so I can't help with that.

I hope that cleared up some confusion.

There are no real differences between the 49G and the 50G except I think the driver installation is started and completed using the CD that also installs the application program. Nothing notable. The back up file is somewhat of a mystery. I don't know what it's for or how it serves to back up your data. Thanks for the information on the back up file though. That's kind of what I figured. Thanks for the information on editing files in the calculator on the computer. That I can do now. The only thing I have left to do, is figure out how to write the program on the computer then send it to the calculator. Doing it on the computer is much easier than doing it on the calculator when doing large programs. Got a quick way to do that?

Like I said the backup file is a snapshot of the HOME directory (and all it's subdirectories) and the alarms. That's in case your calculator crashes or you need to do a factory reset, you'll be able to restore everything as it was. I think you can do the backup to the SD card, so using Conn4x for a backup would be more important for 49g users than 50g users.

Actually, I think there's more than 1 system for writing progs on the PC, check www.hpcalc.org if you want to experiment with different ones. But like I said, I've never used them. If the prog gets kind of large, I sometimes use the EMU48 emulator. Once you get used to the keyboard assignments, it's pretty handy and goes faster than on the calculator.

Thanks a lot, I'll check it out.
