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 Automated Solutions OPC Server for Modbus Serial from
www.automatedsolutions.com/products/opcmodbusrtu.asp. This OPC server is
easier to configure but can not be started as a service. It includes very
simple and limited OPC client for quick data access testing of OPC DA
servers, so I recommend using Matrikon OPC Explorer again. Installation
will also install all necessary OPC Foundation DLL files and register them.

3. Install and start server and configure it by loading "AvrCo.tdb"
configuration file into it.

4. Check if you have AVR device with modbus demo attached to COM2. If not,
modify it to suit your configuration.

5. Test OPC server by clicking on "Monitor mode" toolbar icon. You should now
see tags from your AVR device changing every second.

6. 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.
