Enabling Ethernet
Bridging
MDS 05-4846A01, Rev. C
The following points apply to the use of Ethernet Bridging:
• Bridging is only available on radios configured to operate in
Packet Mode.
• Ethernet Bridging must be enabled at both the Master unit and
each Remote radio that requires Ethernet communications.
• Ethernet Bridging may be used for remote RTU diagnostics as
well as for MODBUS TCP polling, although poll times may need
to be extended due to the narrowband transmission mode used.
• Because bridged networks may asynchronously send data
through a narrow "pipe," they tend to have more data collisions.
It is therefore recommended that Bridging only be enabled when
it is required, such as for pinging or performing management on
a remote terminal unit (RTU).
• To minimize the chance of collisions, the radio's Listen Before
Transmit (LBT) feature should always be configured when Ether-
net Bridging is used.
• The transceiver is still able to pass serial polling and IP payload
data (which is distinctly different from Ethernet Bridging data)
during the time that Ethernet Bridging is active.
• Remote configuration of radios via Telnet is available when
bridging is enabled. However, it is recommended that all data
acquisition be temporarily suspended during remote configura-
tion sessions.
The Bridge Configuration Menu is shown in Figure 52. This is where
Ethernet Bridging can be enabled and various filter parameters set as
required for your network.
