PCMCIA CAN-2 under Windows 2000

[zoletnik]

I cannot make a PCMCIA CAn-2 interface run under windows 2000. I have downloaded the newest software from the NI site and installed it several times (after unistalling and reboooting) with the software cannot find CAN hardware. Under NT it worked correctly.

Hello-

After downloading and installing the latest NI-CAN driver from ftp.ni.com/support/ind_comm/CAN, be sure to map the ports to the proper network interface objects. In Windows NT/2000, open Control Panel and use the NI-CAN configuration utility. In Windows 9X/ME, open Device Manager and click on the properties of the desired CAN card to get to the configuration utility. In the configuration utility, click Port1 as CAN0. Then, for two-port boards, select Port2 and click CAN1.

After the board is properly configured, be sure the powering is set properly. For non-PCMCIA cards, there is a jumper label "int" for internal and "ext" for external power. For PCMCIA cards, the type of power is determined at the time of purchase.

Also, some Windows NT system
s use PCMCIA socet services. Our CAN cards usually have problems with these services. It is recommended to use the native Microsoft PCMCIA socet services.

Thank you for the response. It turned out that the problem was that I have installed the downloaded 1.5 version driver from the harddrive. After rebooting the system the installation was not completed, the PCMCIA CAN card driver wasn't started. When installing from CD I had no problem.

However, we have another problem. After running our Borland C program (based on NI-CAN) for a while the PCMCIA CAN/2 interface hangs. We get very strange error messages and at this point even the NI CAN diagnostics fails. Restarting the computer helps. We have tested this on 3 types of notebooks and it happens on all but it is not repoducible. Do you have any idea what to test? We suspected overheting but it can be a problem with the driver or even with our program as well.


Thanks
