I am attempting to communicate with a Neslab Chiller. The instrument takes hexadecimal commands. In NI VISA Interactive Control I am able to communicate and get the correct responses back from the instrument. Unfortunately, when I attempt to communicate in labview using VISA read and write I keep getting a VISA read error (a timeout error) and the instrument cannot be controlled. I know there is some weird catch with having to different programs calling the same instrument, so I make sure every time to just labview open and not NI VISA Interactive Control. I also am very careful to match the baudrate, parity, last bit, and end mode for the read and write commands. I have attached images of the NI VISA Interactive Control Settings that were successful as well as my thus far unsuccessful labview vi. Please help me! Thank you in advance!
