Free advice.
Before attempting any such project, buy a line analyzer. Today's
implementation is a piece of software that runs on a laptop with a =
cable
that lets the PC site between the two devices.
The software allows the PC to monitor the communications and it will =
greatly
ease your work.
I simply can't make serial links work without such equipment.
Here's a web page that you can use to see what I'm talking about:

I bought Serialtest ComProbe (Sync/Async) for Windows 95/98/Me/2000 or
Windows NT TD115V-R3 =20
With this and a little knowledge of the Modbus protocol, you'll figure =
it
out.
Without this? It's going to take awhile.

Subject: [foxboro] FBM224 and Atlas Copco Elektronikon
Has anyone out there worked with Modbus communications between the =
FBM224
and the Atlas Copco Elektronikon Sequencer?
I have a good communications line between the two and still no talking
taking place.
Anyone have any ideas? Like dip switch settings on the FBM224 TA? =20
My next step may be to have the Atlas Copco folks come in and assure me =
they
are trying to send information.
Thanks
