Bk9121 Driver Error code

[WDLV]

Hi, I downloaded and installed the BK9121 driver from NI but when I tried to use the example code I get error -1073807339 occured at VISA Read in BK9121A.lvlib:Initialize.vi->BK9121A Output DC Volts.vi (HEX 0xBFFF0015, timeout expired before operation completed).

It seems to be related to wait for DSR which simply times out, *IDN? also times out. I did test the instrument with direct VISA (intitialize, write, read) and MAX Soft panel and they work but the driver from NI does not....what to do?

Hello,
I noticed that the driver using flow control DTR and DSR but during the initialization the flow control parameter of the property node is set to 0, please try setting this to 4.
Let me know if this helps.
