Establishing Communication with Controllers

The software polls addresses 3 through 254 at 9600 baud.

The network is ready to operate at 9600 baud.

To use the automatic function:

1.Make sure all the controllers are powered up.

2.Use the front panel display and buttons on controllers that do not support the Omega Plus protocol to set their communication parameters to 9600 baud, 8 data bits, no parity, 1 stop bit. (The baud rate of controllers that support the original Omega protocol can be read, but not changed, by the CN8-SW computer.)

3.While you are logged in as MULTI (or another user with Controller Configuration Privileges) select Options Start Find Controllers. The process will begin.

4.You will be able to monitor the progress of the operation. A message in the status

bar (lower right corner of the main CN8-SW window), will be displayed: ÒChecking for a controller at ID. 8

5.As each controller is found, an image of its display will appear in the main CN8-SW window. By default the name of the controller will be the same as its address number. You can give each controller a different name later (see 4.6).

6.When you see that the controller with the highest address number you assigned has been recognized (appears on the main display), you can stop the process using Options Stop Find Controllers.

7.After the find controller function has been completed or has been stopped as described in Step 6, the CN8-SW software will begin normal operation at 9600 baud, polling the controllers and displaying their PV and SP values.

8If the CN8-SW status bar is not visible, use the View menuÕs Status Bar item to display the status bar.
