DESCRIPTION

ACCESSORIES
0-073-0902-0 Terminal part TAC Xenta 400
0-073-0920-0 TAC Xenta: Programming Serial Kit
The TAC Xenta 911 communication device can be configured in three
different ways:
• As a LonTalk
®
adapter between TAC Vista and a LonWorks
®
network
• As an IP modem, working as a direct replacement for a telephone mo-
dem, with dial-up functionality over the computer network
• As a remote serial port, meaning the serial port of Xenta 911 can be used
as if it was a serial port on the PC. To be used for the serial protocols of
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 con-
nection, and it is pre-configured for most TAC products.
The TAC Xenta 911 contains HTML pages providing comprehensive on-line help.
