I don't think that DAQmx VIs support Traditional DAQ devices.

Thanks for posting to the NI discussion forums. Unfortunately, JoeLabView is correct. Your PCI-6713 is not supported in NI-DAQmx for Win 98, and so you can only use Traditional NI-DAQ VIs to program this device. The PCI-6036e is supported by both NI-DAQmx and Traditional NI-DAQ for Win 98. This is why the PCI-6036e can be seen as both a NI-DAQmx and Traditional NI-DAQ device in MAX and the PCI-6713 is only seen as a Traditional NI-DAQ device.This information can be found in the readme for the latest driver version supported on Win 98. By visiting the NI-DAQ Driver Support: PCI/PXI Devices page, and looking at support for the NI 6713 you can see that NI-DAQmx support was added for the NI 6713 starting with NI-DAQmx 7.5 supported for Windows NT.
