I have a list of VXI-11 intruments that recognize TCPIP resource strings of this form "TCPIP0::10.AA.BB.CC::INST1::INSTR" with different IP addresses. I connect to these VXI-11 devices manually in NI-MAX Network Devices Tree and open a session. I closed NI-MAX and later I restart it. The NI Trace shows that any time I open NI-MAX it will automatically search for instruments of my previous TCPIP list. I could see that each connection send a viLock then an IDN? then viUnlock. The time taken between viLock and viUnlock is around 40 ms but if in this time some other program want to acces my device it will receive "Device not accessible" because NI-MAX locked the device.How may I prevent NI-MAX to start do this automatic search for all VXI-11 devices stored previously in NI-MAX? How may I prevent NI-MAX when searching for VXI-11 device list to send viLock and viUnlock in the sequence: viLock IDN? viUnlock and send only IDN?
