Hello.
I am having problems getting my cRIO to control my Keithley 2400. I have the two devices connected through an RS-232 cable. I can find the Keithley using MAX under the Serial & Parallel options and it says the device is working properly.
I open the VISA Test Panel, and in the Input/Output
Write: *IDN?\n
Return Data: Write Operation (*IDN?\n)
No Error
Read: *IDN?\n
Return Data:
Read Operation
Error
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.
KEITHLEY\sINSTRUMENTS\sINC.,MODEL\s2400,4049517,C32\s\s\sOct\s\
s4\s2010\s14:20:11/A02\s\s/U/K\r
Why is it giving me a timeout error, and then giving me the expected data?
I'm new to serial programming and still trying to get the basics.
Thank you in advance.
