Hi All,
I have been trying to communicate serially with a mass flow controller (Alicat MC series). I can successfully do this using a terminal (RealTerm). However when I try to do this on labview I am getting no feedback. What I'm trying to do is set up a loop that writes then reads the changes caused by the command. I have followed the basic serial read and write template with no success, and I have also tried using the NI MAX application for testing, and I have had no luck using that either. It claims to successfully write but then says the device is timed out. I tried increasing the time out number but still no luck. I am thinking this is a software issue because I can successfully communicate using a terminal. I have verified that my connections work and I have all the right settings i.e. baud rate, parity, etc. I have attached my program, if there are any errors that anyone can point out, that would be appreciated.
