One other thing. I'm assuming I do not need a scan card in my Keithley 2000 to run this VI. I don't have a scan card, so I hope that is correct.
This might have been solved already but I had a similar issue with the Keithley 6517B where I kept getting the RS232 Break Detected error.
I found out that by removing the VISA Clear function in the Initialize SubVI, this error didn't come up anymore. Hope this helps.
Here is a very basic VISA communication scheme. If you feed the output of the VISA Serial Configure Port primitive into the VISA Resource Name input, then you should be able to send and receive data from the device.
Enter the command above into the write buffer. When activated, it should respond starting with, "Keithley..."
sir i am getting error 803 and 800 on my keithley 2000 multimeter on connecting rs-232 cable.my cable are straight,on taking reading 2 wire resistance,p-lease help regard this.
1) First make sure your Keithley 2000 firmware is as up to date as possible.
2) Next search for the 803 and 800 errors in Keithley manual. (This is a LabVIEW forum, not Keithley.)
3) Start a new thread, describe the code you use and the errors.
I ran into this problem, and the default settings for the Keithley 2000's RS-232 port were different than the default settings for the LabVIEW driver package. Go into the "Initialize" VI and check if the baud, flow control & termination character are the same as what's configured in the RS-232 menu on the Keithley 2000. Otherwise, set them to the same values.
