Read timeout issues SR844 lockin

Hello,

I have a big timeout issue with the communication to my Stanford SR 844 lockin amplifier.

I'm using the labview driver of the instrument. Basically, I initialize first, then  I configure it and when I try to read a data I have a timeout error (-1073807339) on the read. I have no idea of how to fix it, I tried to put some delay etc... but nothing works.

Does anybody have an idea of how to solve this issue ?

Thank you in advance,

Anoulak
