Instructions:
=============

1. Upload HEX file to your AVR and test it with Hyper Terminal or
any other similar tool, by typing commands as instructed in the
PAS source file. You have 1 second timeout for typing each character,
so it would be best to use copy/paste. If you receive response, proceed.
 
2. Download Matrikon OPC Server for Modbus (Plant Based) from
www.matrikon.com/drivers/FreeDownloads.asp. It includes Matrikon
OPC Explorer which is a very nice client for quick data access
testing of any OPC DA server. Installation will also install all
necessary OPC Foundation DLL files and register them.

3. During installation, decide if you want OPC server to be started
as a service or not. If you are not sure if you need it, choose not to.

4. Start server and configure it by loading "Matrikon Modbus OPC server.xml"
configuration file into it.

5. Check if you have AVR device with modbus demo attached to COM2. If not,
modify it in Avrco-com-port.

6. Check if Avrco-com-port and Avrco-device-1 are enabled.

7. You can now exit OPC Server because it will be automatically called
and started by clients when necessary. Your OPC server is ready now.
You can check if it works with Matrikon OPC Explorer.
