ASTM PROTOCOL

[Dzemo]

I need to communicate with lab analyzer using ASTM E1381-91 protocol from my
VB.NET application. Any examples code showing that how to do that or any
control. I communicate trough RS232 port (I already can communicate between
two computers with RS232 control)
thx

Hi,

Do you have a copy of the ASTM E1381-91 document? If so, then implementing
the protocol shouldn't be too hard. If not, then that's the place to start.
Here is a link that shows the details:
http://www.jahis.jp/english/other-information/topics05.htm. This protocol
is fairly complex, so be prepared to spend some time developing and testing
the code. I doubt that you will find any freely available.

I've worked with dozens of protocols, but not with this specific one.
However, I do show the general approach to creating code that implements
several different protocols in my book (see below).
