GadgetGateway Overview

A channel, then, is deﬁned as a group of gateways that all send information to each other.

The lines of communication are open in both directions and to all members—a complete

mesh of connections.

Typically, channels are managed through the use of a conﬁguration server (called Normal

mode see below). The conﬁguration server informs all members in the channel about the

channel information, which includes the adding and removing of channel members. Con-

ﬁguration servers are capable of managing multiple channels, while gateways belong to

only one channel at a time.

709.1 to IP gateways can also be managed manually by conﬁguring each device uniquely

(called Manual mode, see below). In such a manual conﬁguration, for proper operation,

devices must have mutual membership in each other's channel lists. That is if Device A is

in Device B's channel list then Device B must be in Device A's channel list. However if

Device C is in Device B's channel list, Device C does not have to be in Device A's channel

list.

2.1.2 Gateway Modes of Operation

The GadgetGateway can operate in one of two modes:

• Manual

• Normal

Manual Mode

In Manual mode the user has control over the GadgetGateway's conﬁguration only. The

user can change the GadgetGateway's operating information and determine to whom the

Gateway will send information. In Manual mode the GadgetGateway will honor read

requests from other devices or conﬁguration servers, but it will block requests to write or

change internal parameters. This is a more secure mode and may be preferred on open net-

works.

Normal Mode

Normal mode allows the user to view conﬁguration data and channel data set by a remote

conﬁguration server such as an i.LON

sets some of the operating parameters of the GadgetGateway. Conﬁguration servers

mostly manage the device's channel. The channel is made up of other devices to which the

GadgetGateway will tunnel or send ANSI/EIA 709.1 data. In Normal mode the adding and

deleting of devices is managed exclusively by the assigned conﬁguration server, the con-

ﬁguration server providing a single interface to add and delete devices. Finally, Normal

mode permits read access to information by other devices and write access to information

for the assigned conﬁguration server.
