475 Convectron Automated Measurements in Labview

[JT234]

I am trying to acquire automated pressure measurements from a MKS 475 convectron gauge controller using rs-232 interface. Will this only require the basic visa serial functions to do?

Quite probably!  But you are the one with the Manual -- what does it say about how to connect it to a PC?  Do you need a true RS-232 (DB-9 or DB-15) "port" on your PC?  Does it use a USB connector?  

I would suggest getting appropriate hardware (cable, possible Serial-to-USB adapter) to connect your MKS 475 to a port on your PC.  Then open MAX, and see if it can "see" your device.  Assuming it can, you can use MAX to set Baud Rate and other RS-232 parameters and then open a Test Panel and try communicating with your device.

If you can "do it in MAX", you should be able to write the (simple) LabVIEW code to "do it in LabVIEW".

I am going to use a male to female rs-232 cable and I will need to use a rs-232 to usb adaptor because I have another device that is utilizing the only rs-232 port on my PC. I will try to communicate with the controller on NI MAX like you said. I actually do not have the controller yet. I am trying to gather as much information as I can before purchasing it and be prepared to start my experiments asap when it arrives.

Get the (programming) manual for that device to get all the information you need!
