Ppp; Data Buffering; Implementing Configuration Changes; Serial Configuration Wizard - GE MDS iNET 900 Reference Manual

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.
You must configure the multicasted serial port as the target for the mul-
ticast data (for example, multipoint-to-multipoint mode, or
point-to-multipoint mode where the inbound data is multicast). This
restriction is because a host that only sends data to a multicast address
(for example, point-to-multipoint mode where the iNET acts as a point)
will not join the group to receive multicast data because the host's
inbound data is directed unicast data.
The serial-to-serial example which follows shows how to provide mul-
ticast services. (See "Point-to-Multipoint IP-to-Serial Application
Example" on Page 73.)

PPP

External devices can connect to the transceiver using PPP
(Point-to-Point Protocol). The transceiver works as a server and assigns
an IP address to the device that connects through this interface.
To gain access to the transceiver from a PC even if the network is down,
a modem may be connected to one of the transceiver's COM ports that
has been configured with PPP.

Data Buffering

Data buffering is always active regardless of the selected mode. When
Seamless mode is selected, a buffer size of 256 bytes is used. When
custom mode is selected, the size options are: 16. 32, 64, 128, and 256
bytes. The Inter-Frame Delay is settable in either Seamless or Custom
modes.

Implementing Configuration Changes

There are several configuration parameters for the Serial Gateway found
under the Serial Configuration Menu of the Management System. After
making changes to the configuration, you must use the menu's "Commit
Changes" to assert the changes.
If you are connecting EIA-232 serial devices to the transceiver, review
these parameters carefully.

Serial Configuration Wizard

The Serial Configuration Wizard available through the
Serial Gateway
is recommended for configuration of serial ports. The
Configuration Menu
wizard uses a step-by-step process, will eliminate possible conflicting
settings, and streamline complex configurations.
