GFK-1322A
During normal operation, the only external connection to the LBIM is the network connection to
the two-pin removable header on the front panel. The RJ-45 connector is reserved for easy
connection of network management tools during configuration of the interface and binding of
network variables. The RS-422 serial port is used to update LBIM firmware and is not normally
needed by the user.
