"VISA: (Hex 0xBFFF0015) Timeout expired before operation completed signal recovery" with Agilent GPIB card

Now you've disable the controller from sending EOI?

The EOS byte does not look right. It's a line feed which is 0xA. I don't remember if that field is hex or decimal.

Thanks Woodster.

This also fixed my problem, it says timeout error, but it is really conflicts between dlls.

Hi all

I am using the NI VISA I/0 to talk to Keithley SMU 2410 using a PROLOGIX GPIB-USB Controller.

I have correctly configured(I think) the SMU to VISA using the GPIB connection but I'm getting the same timeout error as mentioned in this thread.

The command outputs are the following:

_____________________________________________________________________

Command: *IDN?

   Write: Write Operation (*IDN?)
              No Error

   Read: Read Operation
              Return Count: 82 bytes

              C33\s\s\sMar\s31\s2015\s09:32:39/A02\s\s/J/M\n

After this, I try to use the following command sequence for measuring current by sourcing voltage:

*RST

SOUR:FUNC VOLT

SOUR:VOLT:MODE FIX

SOUR:VOLT:RANG 0.2

SOUR:VOLT:LEV 0

SENS:FUNC "CURR"

SENS:CURR: PROT 100e-3

SENS:CURR:RANG 10e-3

OUTP ON

READ?

The output I get after I read each of these commands is:

Read Operation
Error

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

I am struggling to understand why the I/O is not able to souce voltage on the sourcemeter even when it responds well to the *IDN? command.

Let me know if any more information is needed. 

Thanks!
