Base Converr The Base Converr has two Ds. The upper D labed BOARD OK flashes when the has poweredup passed its diagstic sts and is waiting for configuration data from the . Afr receiving configuration data the Board OK D is turned on if the data from the is OK; it is turned off if there is a configuration error. The lower D labed PORT OK turns on when munication is established with one or more Expander s and the expansion bus is operating properly.
