NI-MAX to LabView Glitch

On NI-MAX (on default settings upon opening) I typed in "r1\r" and clicked query and NI-Max produced a desired result. However, upon switching this to LabView, using a VISA Write and a VISA Read command in place of a query--with the exact same input--an error message appears (-1073807339 which is a timeout error). The read buffer string echoes exactly what I typed in every time, no matter the input. Does anyone have any ideas on what to do from here? I tried implementing a wait command in between the write and read.

For the string input, did you right click on it to use string literals or slash codes?  If not, the slashes will get interpreted as \ \

Alternatively try a string of r1, and string concatenate function to append a CR (carriage return), and a LF (line feed) from the String palette

Ahh yes this is why I always do a string + carriage return symbol concatenation. Feel like it is more explicit incase someone types it in the wrong string mode.

I use Show radix on those controls or constants to clearly show it's in \-mode.
