UDP Multicast IP provides a mechanism to perform a limited broadcast to a specific
group of devices. This is known as multicast addressing. Multicast
addressing requires the use of a specific branch of IP addresses set apart
by the Internet Assigned Numbers Authority (IANA) for this purpose.
UDP multicast is generally used to transport polling protocols typically
used in SCADA applications where multiple remote devices will
receive and process the same poll message.
As part of the Multicast implementation, the radio sends IGMP mem-
bership reports and IGMP queries, and responds to membership queries.
It defaults to V2 membership reports, but responds to both V1 and V2
queries.
The
Point-to-Multipoint Serial-to-Serial Application Example on
Page 83 shows how to provide multicast services.
Data Buffering Data buffering is always active regardless of the selected mode. If you
connect EIA-232 serial devices to the transceiver, review these parame-
ters carefully.
Serial Configuration Wizard
GE MDS recommends the Serial Configuration Wizard, available
through the
Serial Port Configuration Menu, for configuration of the serial
terminal services. The wizard uses a step-by-step process, eliminates
possible conflicting settings, and streamlines complex configurations.
You can bypass the wizard by selecting option
B) View Current Settings
and adjusting the individual settings of the appropriate parameter.
