M Series or S Series Devices Are Not Detected During Installation on Some ComputersHardware: Multifunction DAQ (MIO)>>M Series, Multifunction DAQ (MIO)>>S Series
Problem: My M Series and S Series devices are not detected by Measurement & Automation Explorer (MAX) or the Device Manager of the Windows 2000/NT/XP operating system. When using other devices (such as E Series devices) on the same PC, they work fine. What is the problem? Solution: The M Series and S Series devices require +5 V, +3.3 V, +12 V, and –12 V supplies from the PCI bus. This is a standard PCI specification. Note: The only M Series device that does not require the +3.3 V supply is the PCI-6221 (37 pin device). The only S Series devices that do not require the +3.3V supply is the PCI-6110/6111. The PCI-6010 (B Series) device also does not require the +3.3V supply. Some PCI bus slots are not fully compliant and only provide +5 V, +12 V, and –12 V. M Series and S Series devices will not run on these computers. E Series devices only use +5 V and thus, will still run. M Series and S Series devices use these additional power rails to provide 5 V power with 1 A current on both connectors (for boards with two connectors) and up to 48 high-current digital I/O lines. There are a couple of ways to verify that this is the problem. The best solution is to find the manufacturer information for the motherboard. This should include information on the voltages supplied by the PCI bus. The other solution is to install the M Series device on a newer computer and see if it works. You can also test your system to see whether or not it is providing the 3.3V rail with a DMM. One of the RTSI lines (RTSI OSC) shows the 3.3V rail voltage on power up. Measure between RTSI OSC and the compter's chassis while the computer is booting up. If you see 3.3 volts on the RTSI OSC pin, then your computer has the 3.3V rail. If you see no voltage on the pin, then your computer does not have the 3.3V rail. You can refer to the following KB to see where the RTSI OSC line is on the RTSI pinout: KnowledgeBase 0Z98SOYP: RTSI Connector Pinout The following is a list of computers that NI has determined do not provide the necessary power rails to support M Series or S Series devices.
