Ethernet Communication Device

The TAC Xenta 911 Communication
device can be configured in either of
three ways:

• As a LONTALK® adapter (LTA) between
TAC Vista® and a LONWORKS® network.

• As an IP modem, working as a direct
replacement for a telephone modem,
with dial-up functionality across the
computer network.

• As a serial gateway, allowing computer
software, such as TAC Vista, to use a
serial port on the TAC Xenta 911 as if it were
physically connected to the computer.

As an LTA, the Xenta 911 may be configured for conti­nuous communication or, to reduce traffic in large net­works, for event-driven, low bandwidth communication.

As an IP modem, the TAC Xenta 911 is intended for use
with all units that support dial-up listed in the figure
below under the ‘System Architecture: IP modem’
header. The IP address of the unit ’dialed-up’ will then
replace the telephone number.

This makes it very easy to save money
by eliminating phone charges. The fast
dial-up time, typically less than two
seconds, provides the feeling of a fixed
network.

The TAC Xenta 911 can be used with
ISDN, for example, via a dial-on­demand link.

As an RS232 serial gateway, Xenta 911
helps integrate systems using serial
ports with modern systems with IP
networks as backbones.

The TAC Xenta 911 is quick to install and easily main­tained, using TAC Vista Explorer. Its default values are
set for TAC Xenta connection and it is preconfigured for
most TAC products (please refer to the list on the next
page).

The unit contains HTML pages providing compre­hensive on-line help.

SYSTEM ARCHITECTURE: LTA

The TAC Xenta 911 can be used as an

ONTALK Adapter, between TAC

LTA, L
Vista

and the LONWORKS network (Fig-

ure 1).

TAC Vista may communicate (although
not simultaneously) with up to 800
TAC Xenta 911s, if they are set to
event-driven mode.

UNITS THAT CAN BE CONNECTED: LTA

When using the TAC Xenta 911 as a
LONTALK Adapter, any LONWORKS
network can be connected.

Continuous Communication

When the TAC Xenta 911 is configured
for continuous communication,
TAC Vista can be configured for up to
30 TAC Xenta 911 connections.

Event-driven Communication

When the TAC Xenta 911 is configured
for event-driven, low bandwidth
communication, TAC Vista can be
configured for up to 800 TAC Xenta 911
connections.

To reduce the network load, only a
certain, configurable number of these
are allowed to communicate
simultaneously.

SECURITY

The TAC Xenta 911 utilizes SSL
(Secure Socket Layer) to guarantee a
high level of security.

The unit is protected against both un­authorized access and incorrect
operation.

The security mechanism is based on
https transfer and the use of 128 bit
encryption keys. This level of security is
considered to be very high and is used
by many international banks and e­commerce sites.
