Answer» Hey everyone, wasn't exactly sure what category to put this in but here it is anyways.
I have a TI-83 Plus that I recently got from the school that I attend. I have put most of my apps on it from my TI-84 Silver Edition through a direct serial transfer between the two and it got done very quick and I could do things very quick. The person who gave it to me was also gracious enough to give me the TI graph link cable, but alas, it is the serial version. I tried to use a USB to serial converter and yes it did work but it is un-godly slow. It took about 15 minutes for a 106 KB app to go through using the converter. This seems very strange and I think the data should be moving a little bit faster than that.
I know I have the correct drivers as they are from the manufacturer's website, I'm just at a loss. From now on I think the BEST bet is to transfer apps onto the TI-84 via the USB port and then transfer from the TI-84 to the TI-83. That seems like the FASTEST way so far. If anyone has any ideas or suggestions, I would be willing to give it a try.It might help if you explain what is a TI-83 Plus device.
Is it this?

As to the question of speed.
USB can move data up to 480 mega bit per second.
Older RS232 serial has, as I recall, a top speed of 115 kilo bits per second.
That is three orders of magnitude slower!
Or,to put it another way, slow is normal. Yes, geek is is a graphic calculator. I only thought it was quite slow because of the rate of transfer between two calculators . See, if you connect two of them together using the Texas Instruments calculator link cable (Which looks like a 2.5 mm circular jack) it takes about 5 seconds to transfer maybe three apps ACROSS the two. But, when I plug it into the computer using the Texas Instruments Serial Graph Link Cable it is very slow, not even close to speed between two calculators talking to each other.
So, what I am wondering here is if it's an ISSUE with that USB adapter being slower than it should, compatibility issues slowing down data transfer rate (since I am using windows 10 for this), or just the serial protocol just somehow being that slow? I keep thinking that the serial protocol could not be this slow because if I wanted to transfer 106 KB across to a calculator, I don't think it should be taking this long.
Oh well, I guess one day I will invest in one of the Transparent USB Graph Link Cables from Texas Instruments. OK, here is some more information.
Serial connection for a IBM PC is often called "RS 323" interface.
Here is a general reference:
https://en.wikipedia.org/wiki/RS-232#V.24
Notice how the subject applies to a personal computer that conforms to the original IBM PC design. The speed can not go above 115200 baud.
If you are a student of electronic technology, the above web page has history stuff you need to know.
You can get a user guide for the TI (Texas Instrument) calculators. Inside the guide you will somewhere find details about how the TI serial connection is much faster than the PC connection when using RS232.
If you want a fayer speed, you will need to look into information from TI about what stuff they have for doing high speed data transfer to a PC. Perhaps TI makes a direct interface to USB, If so, that would be the best choice.
Quote Connects TI graphing calculators to Windows-based and Mac-based computers. Gives you the ability to add software and programs from the Internet. The connectivity kit is essential for updating the OS and APPS for Flash BASE TI graphing calculators. Allows you to store programs and data on your computer. Great for backing up TI calculator memory. Includes a CD with TI Connect software, TI Graph Link software and guidebooks for TI compatible calculators: TI-73, TI-82, TI-83, TI-83 PLUS, TI-89, and TI-92 PLUS.

You will need to search for a device that lets you use a USB cable.
Try this phrase: CELLSHEET CONVERTR
Maybe this will help you.
Thank you very much Geek! They do have a direct cable from USB to the 2.5mm Jack, but I'll pass since I don't wanna spend any money on it.
Thanks again!Please create your own topic Lincoln, I would be glad to help once you do. There are a lot of ways some companies use USB interfaces.
In some cases they abuse the standards for economy and convince.
This post is not a general tutorial about all the ways people use USB.
Lincoln021, start a new thread in the hardware forum and somebody will help you shortly. Specify which OS you are using and specific details about the USB hardware.
It makes difference. Windows 10 can interface some devices that Windows 7 does not know about. Hi, how did you get it working via the serial-usb adapter? I connected mine the same way and it didn't show up in any softwares I tried. Any help would be very much appreciated.

If you have a problem with which you need help, you should start a new thread. Posting in a two year old thread will probably not get you the answers you need.Oh, sorry
