4.6Changing Baud Rate after Communication Has Been Established

You can use the CN8-SW application to change the rate of all controllers that support the Omega Plus Protocol. As soon as you change the rate, you will lose communication with the controllers. Once all the controllers have been set to the same new rate, change the CN8-SW communication setting to match. Detailed instructions for changing the baud rate follow.

To change the baud rate after communication has been established:

1.While logged in as MULTI (or another user with View/Change Parameter privileges), select the controller by clicking on it in the main graphic display.

2.To see the present values of the configuration parameters stored in its non-volatile memory, select Controller Parameters. The parameter window for that controller will open. By default, the Input ÒtabÓ will be on top.

3.Click on the Comm tab. The communication parameter values, including baud rate, will be displayed.
