My Texas Instruments ti-92 has

My Texas Instruments Ti-92 Graphics Calculator has a faulty serial port - the connection port looks as if it may be damaged, and there is no connecting signal when it is linked to a PC serial port using either of 2 available Ti-Graph Link cables. What are my options for getting this hardware problem fixed? For example, can I arrange for an alternative communication path thru the machine's 8-pin 2cm secondary port, which I so far have been unable to find information on? If so, where do I obtain the information and support software (if any) - any additional required software (I currently have Fargo II in the Ti-92) will have to be uploaded manually. Thanks.

Trying to download apps but it won't register the fact that my calculator is connected

Use the TI USB Silver cable or a standard USB to Mini USB. The calculator shipped with one or both cables.
Before it can be recognized you must install the drivers. Download TI connect and install it on the computer before connecting the calculator. If you use the Graph link (black cable) you need to have a serial port on the computer.
COM3 is serial communication port. On newer computers (laptops) that port is no longer available.

What do i do with my black wire(cable) that came with my calculator, i bought this calculator from walmart

The cable that has terminals like and audio cable is an Input/Output cable. You use it to connect two calculators through their IO ports.
The TI silver cable with a USB end connects the IO port of the calculator to a USB port of a computer.
If you have a TI Black cable (very unlikely) you use it to connect the IO port of the calculator to a Serial port on a desktop computer. Most recent laptops do not have a serial port anymore.

How to print a graph off of my ti84 plus calculator? i downloaded ti connect, but nothing happens when i click on ti screen capture

You say TIConnect is installed. Ok. Prepare you cable, and your calculator. Draw the graph you want to capture to the computer. Connect the cable to the calculator and connect the other end of the cable to the computer port (Serial port, or USB port). Make sure the calculator is still ON.

Run TIConnect. In the main window click the button TIDeviceInfo. This will launch the communication program between the calculator and the compouter. In the Select TI device the softaware must fin the calculator. If it does not you, will not be able to capture the screen.

Hope it helps.

Whenever i try to link my calculator with other ones it always says error in xmit. no matter what i do

Read the following answer from the TI Knowledge Base.
Hope it helps.

How can I troubleshoot an Error in Xmit error message when transferring data between two graphing calculators?

The Error in Xmit error message is returned when a connection cannot be established between two calculators when attempting to transfer data. There are several factors that can contribute to this error message.
• The calculators being connected are not compatible for data transfer.
• The data cable is not firmly connected to both units.
• The receiving calculator is not in receive mode.
• The I/O port on one of the graphing calculators is damaged.
The procedure for connecting two graphing calculators is as follows:

• Connect the data cable to the I/O port of each unit. The cable will fit tightly in the I/O port and snap into place. If silver from the cable is visible, the cable is not properly connected.
• Access the Link menu on each unit
• Place the receiving graphing calculator on "Receive"
• Place the sending unit on "Transmit" or "Send" from the Link menu.

Once the data has been selected, the transfer will commence accordingly.

The data transfer protocols for graphing calculator is as follows:

• TI-73 - Link allows data sharing with another TI-73, TI-82, TI-83, and TI-83 Plus.
• TI-82 - Link allows data sharing with another TI-82.
• TI-83 - Link allows data sharing with the TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-83 Plus/TI-84 Plus family- Link allows data sharing with another TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-85 - Link allows data sharing with another TI-85(To a TI-86. Not From a TI-86).
• TI-86 - Link allows data sharing with another TI-86 and from a TI-85 to a TI-86.
• TI-89 family- Link allows data sharing with another TI-89 family calculator and from a TI-92 family calculator.
• TI-92 family- Link allows data sharing with another TI-92 family calculator and from a TI-89 family calculator.
• Voyage™ 200 - Link allows data sharing with another Voyage 200 and TI-92 family calculator.

If the cable does not fit properly into the I/O port, or if the I/O port appears to be damaged (broken or separated plastic, obstruction inside the port), call 1-800-TI-CARES (1-800-842-2737) M-TH 8:00 AM - 7:00 PM FRI 10:00 AM - 7:00 PM Central Standard Time to speak to a representative or sending an email to

Cannot connect ti 89 to computer. I have installed the correct software from the ti 89 website for my computer and my calculator when I satart ti 89 connect it tells me there is an error.

Check to make sure TI-Connect is looking on the right port, whether USB or serial. If you have a serial cable, you might consider using Ti's Graph-Link software to connect. I have had trouble getting it to work right with TI-Connect. You can find Graph-Link on TI's Education site under Downloads > Connectivity Software. I personally prefer the free program TiLP, which runs on Windows, Mac, and Linux and supports whatever cable you want. Hope this helps!

Yes you can transfer everything on you YI92/TI92PLus to your computer.
To connect it you need TIConnect software, and a USB TI Silvercable.

Hope it helps
