1) What should I do if the TI Connect software I installed on my computer will not recognize my TI-89? The black cable that was included in your TI-89 Titanium package when you purchased it will not work with all computers. We regret that we can not support this problem. We have spoken with technical support at Texas Instruments; they have told us that when TI Connect software does not properly communicate with a computer, their technical support people will:

ü      Fully support Windows 2000, Windows XP SP1 and SP2, Windows Vista (32-bit versions only);
ü      Offer limited support for Windows XP SP3, Windows Vista SP1 (SP stands for Service Pack); and
ü      Provide no support for Windows XP 64-bit, Windows Vista 64 bit.

We have been told that Windows XP SP2 should work just fine with TI Connect software and the black cable that shipped with your calculator, unless it is a 64-bit version of Windows XP.

Below is a list of troubleshooting steps a technical support person at Texas Instruments has customers perform who cannot get the black USB cable that is supplied with the calculator to work on their computer:

ü    Un-install and re-install the TI Connect software.
ü      Temporarily disable any anti-virus, antis-spam, spyware or pop-up blocker software. Remember to re-enable whatever software is disabled.
ü      Manually install the driver for the black USB cable.

If none of the above troubleshooting steps resolve the issue, please contact Texas Instruments technical support, do not contact WxWare Diagnostics.

Our experience has demonstrated that a different cable, the Silverlink USB Cable, that is available as a TI accessory, works with all computers when connecting to the TI-89 Titanium when using the TI Connectsoftware. This cable is available form Texas Instruments and other vendors. It is sometimes referred to as the GraphLink USB cable.

2) Will the ZipTest Pro3 software package operate on other Texas Instruments calculators in addition to the TI-89 Titanium graphing calculator?
No. ZipTest Pro³ will not operate any other Texas Instruments calculator, including the TI-89 version before the Titanium

3) Can I print ZipTest Pro³ reports?
The answer to this question is no and yes. You can’t print reports directly from the TI-89 Titanium as you would from a PC or Mac computer. However, you can capture what is on the TI-89 screen with the TI Connect software that is included with your calculator and then copy it to a report or save it as a file.

4) Can I save reports I generate in the field so that I can view them later?
Yes, you can save up to eight reports for later viewing. A report is made up of the entered data and answers for any ZipTest Pro³ program or tool. You can’t save ZipTest Pro³ Nugget results unless you screen-capture them with the TI Connect software that is included with your calculator.

7) Can I copy the ZipTest Pro³ software package to another TI-89 Titanium calculator?
No, this won’t work. Before you load your software into your calculator with the TI Connect software that was included with your calculator, you must obtain a software key from us. The software key we generate for you is unique to a particular calculator.

8) If I am using a ZipTest Pro³ program, tool, or Nugget, must I have an additional calculator to help me figure out things like square feet or volume?
No, because we programmed into ZipTest Pro³ a feature called math calculations on-the-fly. So, for example, instead of entering a volume of 8320 ft³, you can enter 26 x 40 x 8 instead. This is a big time saver unique to ZipTest Pro³.

9) Can I set my own default values for items that I use often, like heating degree days?
Yes, you can set default values for a number if items, including fuel prices, seasonal efficiencies, fuel type, weather data, and more. These default values will remain in the memory unless you choose to reset them to the factory-set default values.

10) Does ZipTest Pro³ include the latest calculations for the ASHRAE 62.2 indoor air quality and ventilation standard?
Yes, the ASHRAE 62.2 program includes the infiltration credit (2003) and the alternative compliance method (2009) for existing dwellings.

11) How do I adjust the display contrast on the TI-89 Titanium calculator?
The long answer to this question is in the TI-89 guidebook that came with your calculator when you purchased it; here is a short answer. To increase the contrast, from the home screen press the [¿] (lime green color) key and then the [+] key alternately until the contrast is satisfactory. To reduce the contrast, press the [-] (the subtraction key, just above the [+] key), instead of the [+] key. If the calculator is cold, the energy given off by the batteries will diminish, causing the display contrast to diminish. If you work in a cold climate, it is important that you know how to change the contrast to adjust for temperature changes.

12) Within the ZipTest Pro³ software package, what is the difference among programs, tools, and Nuggets? 
Tools fall between the complexity of programs, such as Weatherization Cost Effective Guidelines, and the simplicity of Nuggets. This is not to say that all programs are complex and all Nuggets are simple, but it gives you a general idea about how we classified the ZipTest Pro³ mathematical routines.

13) Is ZipTest Pro³ available in other formats?
At the present, no. It is likely that in the future we will integrate some of the ZipTest Pro3 software into other programs.

14) When I try to divide numbers with my calculator from the TI-89 home screen (when you escape from the ZipTest Pro³ software package, you are taken to the [HOME] screen or [APPS screen]), it doesn't seem to work. For example, when I divide 89 by 23, 89/23 is displayed as the answer. What is going on?
First of all, this is an issue with the TI-89, not the ZipTest Pro³ software. This is an easy issue to fix (actually, nothing is broken). Press the [MODE] key and then find "Exact/Approx" in the lengthy MODE listings. You will find there are three settings for "Exact/Approx"; "AUTO", "EXACT", and "APPROXIMATE". Set it to "APPROXIMATE", press "ENTER" twice and the "problem" is fixed. Now when you divide 89 by 23 the answer displayed is 3.86957.

15) Why can't I turn off my TI-89 when the ZipTest Pro³ programs are loaded in the working area of the calculator?
There is nothing wrong with your calculator or the ZipTest Pro³ software. When the ZipTest Pro³ software is loaded in the working area, you cannot turn the calculator off by pressing the [2ND] key and then [ON] key. However, your calculator will turn off automatically after two minutes of inactivity (this is the Automatic Power Down feature).

If you want to turn it off immediately, you must exist the ZipTest Pro³ programs by pressing the [2ND] key and then the [F2] key. After you exit the ZipTest Pro³ programs, you may turn your calculator off by pressing the [2ND] key and then [ON] key.

In order to load the ZipTest Pro³ programs into the working area again, from the home screen press the [¿] (lime green color) key and then the [3] key.
