Improved Voice Modem Available

Campbell Scientific’s COM320 Voice-Synthesizer Modem is smaller, lighter, and costs less than its predecessor, the COM310. The COM320 gives speech capability to a CR800, CR850, CR1000, or CR3000 datalogger, thus enabling the user to call the datalogger for a spoken summary of real-time or historical data. When used as a standard phone modem, the COM320 can communicate faster than the old COM310, which transmitted data at 9600 bps. Communication rates up to 115.2 kbps between the COM320 and datalogger are supported. (Your phone lines may limit transmission rate.)
