Figure 1-3. Local Management of a Single Digivance System
An EMS computer may be used to locally manage a networked group of multiple Digivance
systems as shown in Figure 1-4. A Controller Area Network (CAN) port is provided on each
HU. Up to twenty-four HU’s may be linked together through the CAN interface and controlled
by the same EMS computer. All the networked HU’s and the associated RU’s may be managed
by connecting the EMS computer to one HU. The EMS computer provides an RS-232 port (#1)
to support the interface with the networked HU’s.
