cRIO 9076 Kiethley timeout

[RothNRK]

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.

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.

It looks like you have programmed for the wrong termination character. The returned string has a carriage return (\r) and your program may be set for a line feed (\n). Change your code or change the instrument's setting.
