4.2Configuring Communication Parameters and Assigning Network Addresses in Controllers

4.2.1 Communication Parameters

Your goal is to make sure that:

∙all the controllers that support Omega Plus protocol have their communication parameter values set to their defaults

∙all the controllers that support the original Omega protocol have their baud rate set to match the CN8-SW software, and their other parameters set to 8 data bits, no parity, 1 stop bit.

The CN8-SW software is designed to recognize Omega Plus controllers using the controllersÕ default communication parameters. Therefore, if any Omega Plus controllerÕs communication parameters have been changed from the factory defaults, return the communication parameter values to their defaults. The default baud rate depends on the controller series, but all use 8 data bits, no parity, 1 stop bit.

∙The network baud rate will be 9600 if you do use the automatic Òfind controllersÓ function. The software will change each Omega Plus controllerÕs baud rate to 9600.

∙The network baud rate will be determined by the rate you configure for the CN8- SW software if you do not use the automatic Òfind controllerÕs functionÓ.

The baud rate of controllers that support the original Omega protocol can be read, but not changed, by the CN8-SW computer. Therefore, you must use the front panel display and buttons to set the baud rate in these controllers to 9600 (and make sure the other communication parameters are set to 8 data bits, no parity, 1 stop bit) before you use the automatic recognition process described in 4.4.

∙The communication parameters in new (Òout-of-the boxÓ) Omega Plus

controllers were set to their defaults at the factory. If the controllers are new, you can proceed to configuring network addresses (see 4.2.2).

∙If necessary, follow the instructions provided in the controller manuals to

power up the controllers, and use the front panel display and buttons to set all the Omega Plus Protocol controllers to their default communication parameter values (and all Omega Protocol controllers to 9600, 8 data bits, no parity, 1 stop bit), then go on to 4.2.2.
