Agilent 8169A: Visa timeout error when reading response

Hi,

 

I have a Polarization Controller 8169A, to which I am connecting via GPIB using a NI GPIB-to-USB card (GPIB-USB-HS) to connect it to my laptop. 

 

Using "Keysight Connection Expert 2017", I am able to send through all commands but not able to read/query as the connection times out with the error:  

      ! VI_ERROR_TMO: A timeout occurred
      Visa ErrorCode: 0xBFFF0015 (-1073807339)

 

Any idea what might be the cause of the problem and how to solve it? I have already increased the timeout to its maximum, but I still got the same error.

 

Error_timeout

 

Thanks in advance!

Regards,
