ACCESSORIES
0-073-0920-0 TAC Xenta: Programming Serial Kit
The TAC Xenta 911 Communication device can be configured in one of
two ways:
• as a LonTalk
®
adapter between TAC Vista and a LonWorks
®
network
• as an IP modem, working as a direct replacement for a telephone modem,
with dial-up functionality over the computer network
In the first case, TAC Xenta 911 is either always connected to TAC Vista, or
can use the “low bandwidth” configuration to allow many more networks
connected to TAC VIsta.
In the latter case, TAC Xenta 911 is intended for use with most TAC units
supporting dial-up (see the data sheet for TAC Xenta 911). The IP address of
the “dialed-up“ unit will then replace the telephone number. This makes it
very easy to save money by eliminating telephone line costs. The fast dial-up
time, typically less than two seconds, provides the feeling of a directly con-
nected network.
The TAC Xenta 911 is quick to install and is easily maintained, using a web
browser on the TCP/IP network. Its default values are set for TAC Xenta
connection, and it is pre-configured for most TAC products.
The TAC Xenta 911 contains HTML pages providing comprehensive online help.
