How to send LF,CR and EOI in VISA Write function of LabView?
As far as I know you can set just one termination character for VISA.
Therefore it is easier to solve your problem appending "\r\n" to every
instrument related command. Don't worry about semicolons if the old
program is working with them ... it means that the instrument accepts
this kind of command.
Regarding the EOI, I assume (I didn't try it) that you can set it
using VISA Advanced > Property > Message Based Settings > Send End
Enable. Anyway, make sure that you have set EOI on in MAX.
Hope this helps
