    ELO & SB conflict, gurus help!

    I posted in the General Hardware about an issue I am having with an Elo touchscreen setup, but there have been developments that have led me to the software section. The problem is as follows.

    I have a 2310 Elo touch controller (serial connection), and a Surface-wave 10.4" overlay. The setup has been connected and working for about a year. Recently I began having issues with the touchscreen NOT working. Although, i found that the computer was getting the touch signal (the computer beeps when screen is touched), but the mouse was not being relocated. I also tried the touchscreen on another computer and was able to get it working again... so i know that the hardware is no bad.

    I called Elo, and found that there is a known issue with the 2310 serial controller board and many different types of hardware (and their drivers...) One well known issue is with Creative Soundblaster sound cards. I have an SB live value, and the contact at elo said my problems were consistant with that conflict.

    I tried to get as much information from her as possible, but she did not have any details... other than Elo software is working on the problem.

    Here's where all of you mp3car geniuses come in... The problem appears to be a driver conflict. There are 2k and xp drivers for both the soundcard and the touchscreen (running xp), and I have tried every combination of both. Also, there are microsoft drivers that come with XP, but they do not have some of the features that I need (all the 4 channel and mixer settings). What can I do to check where the conflict might be, and what are my options to get this touchscreen working?!?!

    Other Info: The touchscreen softare comes in the form of a control panel applet, a mouse driver, and an Elo Touchscreen service that refuses to start (on the car computer). It should also be noted, that the desktop computer that I tested the screen on DOES have an identical sb live value card, but the screen works. The drivers are stock MS drivers, and after a complete reload of the OS on the car computer, letting the MS drivers install, the screen did NOT work once again.

    Any info or ideas welcome.

    Celeron 850 or PIII 933, SB Live! Value into a stock 4 channel amp, ATI vid, 10.4" sharp LCD w/ allen's controller, Elo SW touchscreen overlay and controller, GPS, TV tuner, FW DVD drive, 4 port serial card, and some other stuff....

    Loads of ideas.

    Seems to me that your sound card just hit its rock bottom. Is there any way you can replace it? SB lives run pretty cheap now-a-days.

    Try that maybe the serial connection on your sound card is dead.

    Another try is to take the sound card out, inspect the contacts where the serial is located, search for hot spots that are chared discolored, look for heat stress. Its a try, but seems that your touble is the sound card itself.

    Yeah, I use linux, and i love it. I have also run into some problems getting this system up and running with all the hardware I want, and now xp is giving me problems. About to switch over, i think.

    And about the sound card... First, there is nothing wrong with it. Like i said, the problem is a driver conflict between the Soundblaster (just about ANY soundblaster that exists) and the serial touch screen. As for the soundcard's serial, could you clairify? What is a soundcard serial port? As for the damage, there is none. It is true that if i remove the soundcard from the system, boot, and let MS take OUT any drivers for the sb live, the touchscreen WILL work.... but there is no damage. And you are right, the trouble is NOT with my soundcard.

    how about getting a RS232(serial) to USB converter. They're cheap ($20-30). It will still obviously use a driver, but maybe the USB driver will be less likely to conflict with other drivers in your system.

    Claylong some SB cards have a serial connector in the back of them. I thought you were using the SB serial connector.

    And thats what I was thinking that can be wrong with your setup, if not, hey atleast I tried to help you out.

    Serial on a sound card? Really? Never seen it.

    Maybe you are thinking of a game port. Soundcard usually DO have those.

    yeah, but the chip is nothing like the standard one used by PCs.
    The chip used by PCs is the 16550 (or one of its incarnations in the superio chip) - National Semiconductor makes thoses.
    The chip used in sound blaster sound cards (or in the big chip on the card now, as all gets integrated) is used for midi output on the 15 contacts connector where paddles and whatnots used to be plugged before the advent of USB. this chip is a motorola 6850 ACIA (same series as the 68XX microprocessors used in the classic 8bit computers, even the 65XX and 63XX are in the same series)

    to make the long story short, the Apple II used the 6502 processor, and a 63XX processor was used in the Nintendo Entertainment System (but most of the work was done by the specialized graphics chip)

    Conflicting drivers? That sounds unlikely. Probably a conflicting IRQ. Check your BIOS IRQ settings and compare them to the desktop machine on which everything worked. You may need to reserve one for the SB card, or you might even have several of them already reserved that dont need to be, you will have to play around with the settings. You can see which ones are in use just after the POST screen and jusrt before the system boots from the hard drive. Hit the Pause key on your keyboard to freeze this display to see what IRQs are in use.

    I am concerned that it is NOT a hardware conflict. I say this, b/c the contact at Elo said that it is a consistent problem with SB and Elo.

    .... Wait a second... The serial port takes an IRQ? The serial device itself does not take an IRQ, so how could they conflict?
