TCP IP VISA Read Error -1073807339

Hello,

I am having a problem reading from an instrument (Julabo Presto A80 Temperature Controller).using Ethernet connection. I can successful ping the unit. And with MAX I am also able to add this as a new TCP/IP VISA resource using manual entry of raw socket using the instrument's port number, and I can successfully send and receive messages using a test panel to the unit within MAX.

 

However, when I close the test panel and try to do this through a vi, I continuously get the timeout error -1073807339 at the VISA Read, with no returned data. To the best of my knowledge, I have configured the connection with identical properties to those used in the test panel. Has anyone encountered/solved this problem? Snippet attached.

 

Appreciated,

PaulR
