## 4.9. No Connection: Data Server-InTouch

### Problem:

There is no connection from the data server to InTouch.

### Cause:

This is a general problem, and could be due to any number of causes.

### Solution:

1. Start Cascade Connect with the debug flag turned on and check the error messages.

2. If there is no connection between Cascade Connect and the data server, refer to the other troubleshooting tips in this appendix.

3. If there is no communication from the data server to your Windows application, this indicates that the DDE service and topic for your Windows application are configured incorrectly in the Cascade Connect configuration. If the configuration of the client service and topic are correct, you should get one-way communication from the data server to Intouch.

4. If you do not have communication from your Windows application to the data server, then look at the DDE server configuration in your Windows application. Only DDE tags in your application will be transmitted to the data server. You must ensure that the DDE server configured in your application is the same as the Client DDE Service and Client DDE Topic configured in the Cascade Connect configuration. If this is correct, you should have one-way communication from your Windows application to the data server.
