10.1.5Configuring Baud Rates

The default baud rate for Liebert IntelliSlots is 9600. To communicate with the OCWEB-LB, Modbus/ Jbus, or the MultiLink cards, the baud rate must be set to 2400.

To change the baud rate (refer to Table 21):

1.Use the Navigation keys directly below the LCD to highlight the Settings Screen.

2.Press F1 to move the highlight into the Data & Settings area of the LCD.

3.Use the Navigation keys to scroll down to highlight the current baud rate across from the appropriate Comm Channel.

NOTE

The Comm channel settings are not immediately visible because of window-size constraints. Scroll down to view them on the screen.

4.Press the Enter (F4) key to select the Comm Channel to change.

5.Navigate to underline the desired baud rate (2400).

6.Press the Enter (F4) key to lock in the new baud rate.
