MAX does not detect an E-series board on a computer without a 3.3V power

[Cepera]

I have an industrial computer in which I use both NI and non-NI boards. All non-NI boards were detected correctly and work fine, but the NI board (PCI-MIO-16E-1) is not detected in MAX. It was suggested that this is due to the fact that this industrial computer does not have +3.3V on its backplane (it only has +/-12V and +/-5V). Can it indeed be the cause of the problem? Thanks, -- Sergey Liberman.

Hello Sergey,

Thank you for contacting National Instruments.

The general rule of thumb with this issue is that if the board fits in the slot, it should work. Most of our boards are keyed in the Universal PCI fashion which will allow them to work in a 3.3V or 5V slot.

Check in the Windows Device Manager to see if the boards appear. You may need to delete the boards from the device manager and then scan for hardware changes so that they will be redetected and then loaded into MAX.

Please let me know if you need additional assistance with this issue and if the boards do not appear in the Windows Device Manager.

Hi Bill, thank you for answering. The board works now, so I am all set, but here's how it went:

I have an industrial computer with a passive backplane with 5 LEDs for monitoring +/-5V, +/-12V and +3.3V. The power connectors were such that both AT and ATX power supplies could be accommodated. At first we had an AT power supply (3.3V LED was not lit). When I called the computer manufacturer asking about the problem with the NI board, he immediately said, "So you are using NI boards - we'll need to ship you an ATX power supply". After I installed the ATX power supply (this time, the 3.3V LED was on), the board was recognized by MAX.

I don't remember if in the first case the board was seen as "Other device" in device manager, but I think it was. The boa
rd is PCI-6115 10 MS/s multifunction S Series.

Thanks, -- Sergey.

Sergey,

I am glad that everything is working for you. It seems that possibly the original power supply did not supply enough power. I would defenitely stick with the ATX power supplies in the future. Take care.
