NI-9178 Reset

[rainman6464]

The C-DAQ was communicating with a computer when the computer unexpectedly shut down.  Now the C-DAQ is stuck in the active state and the active light is always on when it is plugged in.  Even after disconnecting power and all the cables, as soon as I plug power back to it, the active and power lights turn and remain on.  I have tried to connect to two different computers and neither of them recognize the C-DAQ when we plug it in.  Is there a way to reset the C-DAQ?  Or any other solutions??

Hello rainman6464,

Is the active LED amber or green?  Also, what caused the computer to unexectedly shut down? If it was a power supply failure or another hardware failure the USB host controller on the PC may be damaged.

Regards,

The active LED is amber.  The cause for the computer to shut down is unknown, but the screen went completely black as if all power was suddenly lost for whatever reason.  In my efforts to troubleshoot i tryed another computer and the same problem, measurement and automation explorerer cannot even reconize the C-DAQ.  My thoughts are that the C-DAQ suddenly lost connection and is stuck in the active state.

The Active LED being Amber indicates that device is powered on but can't detect a USB connection.  The device's on board firmware is forced to reset every time power is applied, so it can't get stuck in a firmware state unless the hardware is damaged.  I believe the likely cause is that the USB communication portion of the device was damaged in the power event that shut down the machine.  I recommend contacting our Support department to arrange for an RMA of the device.

Even with the chassis empty and with no USB connection, the active light is always a solid amber color when power is plugged in

That's expected.  You can read an explanation of the LED behavior in the NI cDAQ-9178/9174 User Guide and Specifications on page 10.

If the Active LED is lit, that means the device is unable to establish a USB connection.  Since the device cannot establish a connection when plugged into USB, that indicates that either the USB Host Controller of the PC or the USB communication circuitry of the device is damaged.  Since you've tried multiple PCs, that points to the chassis being damaged.

Hello

I have the same problem described by the other user.

If I understand correctly this means that there is a physical damage of the hardware. Is this OK? Would it be posible to fix it?

Yes it is possible, but it would depend on what our RMA team finds in your device.

It would be submitted to several testings and later will be send to repair.
