Error messages that you might receive
Use This If You Are Unsure Of Your Model Of Sound Card Or Video Card:
Sound: Many OEM (Original Equipment Manufacturer) Computers do not have the Sound Drivers for DOS installed. Because your USE2 system operates under DOS, you will need the drivers that enable your sound card in DOS. In most cases you can obtain these from your computer vendor or download them off the Internet. The Internet addresses for some of the more popular sound card vendors are:
Video: If you experience problems with video, you may need a VESA driver or a specific driver for your video card. Like the sound card, there are video card drivers available from most video card vendors on the Internet. Also, a third party shareware VESA driver is available at our website on the links and downloads section. Feel free to download it. Return to TopProblems With Power Management... Many computers include power-saving features that constantly check the COM ports for activity, thus causing communication problems for your biofeedback equipment. Disable all power-management features on your computer. You may need to change your computer's BIOS settings to disable power management. To change your BIOS settings, use the following procedure.
This program performed an illegal operation This error is a result of running the USE2 program in a Windows environment. To fix this, you must modify the properties of the icon (right-click it) and ensure that the program is set to run in MS-DOS. Sample Data Packet Lost This error is a result of running the USE2 at a higher sampling rate than your computer's communication port is capable of. This is usually found when running an I-410 on a laptop or not using a high-speed serial card on the desktop computer.
"The I-330C Is Not Responding" error means that the USE2 program is looking at a specific COM Port with a Specific IRQ number and not seeing the biofeedback equipment. Always check to see that you have the equipment connected to the computer and that the power is on. That is where the majority of problems lie. If you feel you need to re-run the IRQTEST program, refer to configuring your biofeedback equipment for instructions. To see what devices are on which COM Port, perform the following: Open the Device Manager in the System Properties by clicking on the System icon in the Control Panel or by right clicking your mouse on the My Computer icon on your windows desktop and choosing Properties. Then click on the Device Manager tab. Double Click the word computer. You will now see a list of IRQ’s under the Setting tab. Current IRQ Assignments: Make sure that there is no IRQ sharing. (i.e. the same number is not listed twice)
Current COM Ports (Make sure the COM port you Selected is listed here) If you continue to have problems, feel free to contact J&J Engineering Technical Support. "Divide by Zero" Error… This error occurs if there is an error within the hardware, usually if a lead (such as the SCL lead) is shorted. If you can click on OK and then proceed, fine. If not, please contact J&J Engineering Technical Support for assistance. |
