The TAC Xenta 901 is a serial LonTalk® adapter, designed to let TAC Vista reach a LonWorks® network via a dial-up line. When the modem line between TAC Xenta 901 and TAC Vista has been established, communication proceeds as if TAC Vista had been connected directly to the LonWorks® network. 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.
