With BCMS, you can see thecurrent values of each of the distribution branch breakers, letting you measure,plan, and manage power with greater precision.EMS also provides communication options such as network connectivity. ThePower Xpert® Gateway Card installed in the X−Slot® communication bay providesremote monitoring through a Web browser interface, e−mail, and a networkmanagment system using SNMP; connects to a twisted−pair Ethernet(10/100BaseT) network. Modbus® TCP support provides direct integration of thePDR’s parameters to a Building Management System (BMS). It has a built−inswitching hub that allows one additional network device to be connected to thenetwork without the requirement of an additional network drop.NOTE LAN drops for use with the X−Slot card must be provided by the customer.
