Forwarding Mode

Selection of the forwarding mode should be done early on in the setup process. This section will help the
user to identify the most appropriate forwarding mode for their application.
In general, bridge mode will transmit all traffic to all units in the network; unicast, broadcast, and multi-
cast packets are flooded through the network by the Relay Point units. While in router mode, unicast
packets are routed through the system by the IP stack. Broadcast and Multicast packets are flooded
through the system by the Relay Point units. IP Forwarding mode selection depends on user's require-
ments and applications. Table 6 below gives a brief outline of advantages and disadvantages of each
mode.

Station name identifier – Enter string up to forty characters in length
Factory default ID is zero. Dataradio recommends, for security reasons, changing it to
some other value unique to each HiPR-900 network thus preventing collision.

Master (exclusive to the full-featured HiPR90 version) /Repeater (exclusive to the full-
featured HiPR90 version)/Remote
Within a HiPR network, one unit has to be configured as a Master that the remotes
synchronize to. It can be any unit in a system but is normally the one considered the
base unit for coverage and support reasons. By setting a unit to repeater mode, it
becomes possible to extend the coverage of a HiPR-900 network without requiring
back to back repeaters. A unit in repeater mode follows the Master's lead for changing
channels and repeats sync for distant units. Otherwise, it operates as a Remote.
Bridge / Router (exclusive to the full-featured HiPR90 version)– Defaults to Bridge
mode. Use Router for more advanced IP configurations.
By default, the HiPR-900 only forwards IP and ARP packets (Ethernet II types: 0x0800,
0x0806) By selecting the "Everything" setting, the HiPR-900 will forward all 802.3
Ethernet II packets types. Use this setting to transport protocols such as IPX, 802.1Q,
etc.
Note that the "Everything" option is not available in router mode.
Enabled/Disabled (default)
For units that are spread over multiple RF coverage areas, the user needs to identify
the ones that will form the backbone between the coverage areas so that any unit can
talk to any other unit in the network regardless of their locations. The units that are
forming the backbone between the coverage areas are called Relay Point units. Enabl-
ing this parameter will force the unit to repeat all necessary information from one
coverage area to the next.
