TAC Xenta® 911

Ethernet Communication Device

31 Jan 2005

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-on- demand 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 LTA, LONTALK Adapter, between TAC Vista and the LONWORKS network (Figure 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 e- commerce sites.
