Network Topology

5.5.1 One Coverage Area

Shown below are typical point-to-point and point- to-multipoint connections between HiPR-900 units.
See Figure 9 and Figure 10. In a network topology with only a single coverage area (all units can talk to
one another directly), one unit is chosen to be configured as a master and the rest are configured as re-
motes. The connections indicated allow for either Ethernet or serial interfaces. The Ethernet connection
provides Ethernet IP connectivity for network devices. In bridge mode, all the network devices are on the
same IP Subnet. In router mode, the Ethernet connection on master unit and the remote(s) use different IP
Subnets. A hub or switch may be used to allow multiple Ethernet devices to connect to the HiPR-900.
Serial connections are transparent pass-through connections, allowing the use of legacy serial devices in
the HiPR-900 environment.
Note: Master operating mode is exclusive to the full-featured HiPR-900 version.
