In our test system we are using PXI chassis and a custom RF drawer that run on IVI driver. Test software contains a dynamic launch of a vi that has a visa reference node that talks to a com port. Launching of this VI is causing a search for all the Visa instruments then RFDrawer on the test system is resetting. following is the NISPY capture of releative area.
viOpenDefaultRM(0x5D9FF48)
viGetAttribute(0x05D9FF48,03FFF018F,VI_TRUE)
viGetAttribute(0x05D9FF48,0x3FFF0190,0)
viGetAttribute(0x05D9FF48,0x3FFF0190,4)
viFindRsrc(0x05D9FF48,"?*INSTR",0x05D9FF90,37,"COM1")
viFindNext(0x05D9FF90,"COM2")
.

viClose(0x05D9FF90)
I want to know why there is a search for all the instruments initiated and how o void it.
