Campbell Scientific’s COM320 voice-synthesizer modem provides a CR800, CR850, CR1000, or CR3000 datalogger with speech capability—thus enabling the user to call a site for a spoken summary of real-time or historical data. This modem is not compatible with mixed-array dataloggers. The COM320 can also act as a standard modem.
