Hello, I have a problem in connecting a TPC-2006 with WES7 to LV. The device is pingable but LV 2015 won't find the device. Disabling both Firewalls and removing all NI-stuff und reinstalling the run-time didn't work. A few months ago I developed applications with LV 2013 for the device and everything went fine. After this the TPC lay around here for a few months. Now I have to develop a new application for it and it won't work. Is there any way to reset the device to factory default? Or to obtain the original Image? I'm sorry to say but I was too stupid to backup the disk before developing... Thanks in regard for any help. As I have to develop the new stuff asap any help is welcome. Regards Wedgewood
