Hi,
It is possible to access logger data remotely using either a radio modem or a telephone modem.
Radio modem
One computer can maintain radio modem links to several remote loggers. Because EnviroMon requires very little power, the remote loggers can easily operate using a battery that is kept charged using a solar panel. The logger has built-in power saving features to turn off the radio modem when it is not required.
Telephone modem
The EnviroMon software running on a PC can use a modem to make a telephone call to a remote logger, then extract data from the logger and terminate the connection.
The logger can be configured to permit the modem to answer telephone calls only during a narrow time range. This means, for example, that the logger data can be downloaded at night using a telephone line that is allocated for other uses during the day.
Best regards,
Regards,
