Step 2 - Setting up windows ODBC driver
In order to use Access you need to set up an ODBC connection. Click on Start / Settings /Control Panel / Administrative Tools and click on the "Data Sources" menu item.(Figure 2) .

The following window opens: ODBC Data Source Administrator (Figure 3.) In this window select the  System DSN (1) tab. Then  click on Add (2).


On the Create New Data Source form, select the Microsoft Access Driver (1) and click to Finish (2). (Figure 4.)

This brings up the ODBC Microsoft Access Setup (Figure 5.) form. Set the Data Source Name to MSAccessSystem  (1) write some Desciription (2) Click on Select (3).  Open the preveously downloaded file, or the file you have created yourself: ozeki_ms6_released.mdb. 


Step 3 - Configure OZEKI  MESSAGE SERVER  to use database  connection
This can be done by opening the Plugins menu. Select the Installed Plugins menuitem (Figure 6.)  


When the form is open, select the database plugin to install. (Figure 7 .)


Next  click on Configure! (Figure 8.)


If you want to use the database for sending and receiving messages place  checkmarks into the Use database for receiving  SMS messages and the Use database for sending SMS messages checkbox (2,3). Important: place a checkmark into the Auto connect on startup  checkbox (4) as well, to make sure, when you re start the program the database connection will start up automatically. You can  define a  database connection by clicking on  Build database connection (1) (Figure 9.)

Sending sms via MS Access
When the server  starts, go to Access and send a message, by inserting a new record into the ozekimessageout table. You must specify the receiver, enter the message in the msg field and set the status to send! (The incoming SMS messages will appear in the ozekimessagein table.)
