[. . . ] How to check communication between Console and visualiser through the RS232 lead. Testing the Console and the RS232 lead: Set the Console to `visualiser' mode.

If not then the chances are the console is not working correctly, contact Avolites technical support. Testing connection on the PC side: Connect the D type back to the PC. Set up visualiser to test the serial connection: Run the Visualiser program Go into Design mode Click on the `Advanced' menu Click on `Serial Comm' Set the correct com port Select the baud rate to 38400 Checking the data from the console to the PC Make sure the console is still set up as it was for the previous test. In the main white part of the screen you should see a number of letter Z's appearing one after the other. If this is the case then the PC is receiving ok, go to the next section below. If this does not work try selecting another com port and make certain the D type is plugged in to the PC If neither of these work the problem is within the PC or the operating system set-up.
