Bronkhorst with MATLAB !

Hello, I'm trying to use MATLAB to communicatre and control Bronkhorst EL-FLOW Select series. ASCII can be generated by MATLAB and that's something interesting for me. It is possible to use FlowDDE channels for windows application (like excel, LabVIEW, Visual Basic,..). For a lower communication level, FLOWB32.DLL enables reading and changing parameters. Also Bronkhorst provides a special protocol for communication between the devices when operating a FLOW-BUS that'd drive the interfaces directly. RS232 or the FLOW-BUS interface can be initialized through ASCII strings. I'm trying to learn how to establish this with just MATLAB. Is there a publicly accessible dll library or a list of the functions and the parameters they accept or return with regard to my concer here? And also is there another better approach to my interest that I'm not aware of? I'm using Bronkhorst for the first time and I'm looking for inspiration to accomplish this. Any advise is much appreciated. Thanks :)

Regards, Ram.

I'm trying to solve the same problem. I will follow the discussion.

At the moment, the only way through the DDE is to write on an excel file and to read it. but it is annoying since you need to inizialise the link between the excel cell and the DDE each time you run the DDE.

Is FLOWB32.DLL a 32 bit DLL or a 64 bit DLL? If it is a 32 bit DLL then it cannot be called from a 64 bit MATLAB.
