If this BME is equipped with a redundant controller, the primary and
redundant controllers must be configured for the same communications
protocol.
If changing the configuration of an installed board, open and remove the front
door.
If changing the configuration of an installed board, turn the left and right
knurled knobs on the fan assembly door ¼-turn counterclockwise. Raise the
door and rest it on the roof of the power distribution enclosure.
Do not touch the electronic components or the connectors on the power
distribution plane or on the circuit boards without being electrically
grounded. Handle circuit boards by their edges only. Electrostatic
discharge (ESD) can damage ICs, even if you cannot feel, see, or hear it.
Set DIP switch 3, on the rear edge of the controller board (figure 6-8), to the
Off position for RS-232 or to the On position for RS-422.
The controller board is shown removed for clarity, but the board does not need
to be removed.
