We recently installed a new NI Slot 0 controller. We have external GPIB devices connected to it. (i.e. not VXI GPIB cards.) In our old system, everything worked together properly. In this new system, although MAX sees the GPIB devices, when running our program, the GPIB devices are NOT recognized - expect when NI-Trace is running. We tried running NI-Trace to see what is going on, but everything works when NI-Trace is running. When NI-Trace is stopped, the GPIB devices are no longer recognized. But when NI-Trace is started again, the GPIB devices are recognized, and everything runs properly. Has anyone seen this before? Does anyone have any suggestions as to what or why this is working (not working) this way? We tried re-installing the drivers, reinstalling the NI Software (including Trace) and moving things around (like changing GPIB addresses, etc.) and still no resolution.
