TAC Xenta 901
Serial LonTalk
®
Adapter
The TAC Xenta 901 is a serial LonTalk
®
adapter, designed to let TAC Vista
reach a L
ON
W
ORKS
®
network via a dial-up line. When the modem line be-
tween TAC Xenta 901 and TAC Vista has been established, communication
proceeds as if TAC Vista had been connected directly to the L
ON
W
ORKS
®
net-
work. The dial-up can either be initiated by TAC Vista, or by the TAC Xenta
901 unit. TAC Xenta 901 has functions to reduce the connection cost, such
as delaying a dial-up in order to collect more events, for example alarms,
so that several events can be reported at the same call. It is also possible to
specify dial-up to occur at a certain time of day, when the phone rates are
lower.
