Caution:ąYou must complete the internal configuration of the
BM85 before making the unit active in your application, both
on the Modbus Plus network and at its serial ports.
If you are installing a BM85 that was previously configured for
another application, another network, or a different node, the
unit will still be retaining its previous configuration setup.
You must not connect the unit into the current application and
apply operating power to the unit until you have reconfigured
it for the current application.
