there is no conectivity with ni pxi-8145. User1 light remains on all the time.

[Carleins]

Connectivity with NI PXI-8145 is suddenly gone.  I tried to reset the IP address using the toogle NORM/IPRST, but it is still imposible to even detect the device.  MAX cannot detect it even though the workstation (PC) senses a network.  Also, the USER1 light is on all the time (and it is supposed to blink).  What should I do.  Is it a problem in the card (PXI-8145) itself? or may be related to the chasis (pxi - 1031)?  if there is any damage, what could have caused it? is there any reparation center anywhere? how much would it cost?...

K-lyn,

Has the controller ever worked properly?  Using FTP, look at the NI-RT/STARTUP folder (type ftp://x.x.x.x/ni-rt/startup in Internet Explorer, where x.x.x.x is the controller's IP address).  What is there?  If you connect a monitor to it, is anything displayed?  If so, what is on the screen?

Your User1 LED is on constantly.  The LED blinking sequence is documented in the User Manual on page B1.  Constantly on is not one of the choices.  When you power cycle the chassis, does the controller start up with the User1 LED on, or does it blink and then stay on?
We can start from scratch by uninstalling the software on the controller and reinstalling it.  To uninstall it, manually put the controller in SAFE MODE (switch S2 - see the PXI-8140RT Series User Manual pp.2-6 and B-2 for details).  Right now, booting with S2 switched uninstalls the software.  Put the switch back to normal and then reconfigure the controller.

What IP settings are you giving the controller? What version of LabVIEW Real-Time are you using? Which drivers are you putting on the controller? What are the IP settings of the host PC? What is in the program you are using? Are you calling any C code or DLLs?
