COM320 COM320-1
COM320 Voice Phone Modem

The COM320 is a voice-synthesizer modem that adds speech capability to a CR6, CR800, CR850, CR1000, or CR3000 datalogger. This capability allows the user to call a site for a spoken summary of real-time or historical data. The COM320 can also act as a standard modem.

The COM220 has a CS I/O port, power terminals, screw terminals, and an RJ-11C jack. The data logger connects with the CS I/O port via an SC12 or SC12R-6 cable. The RJ-11C jack is for attaching a surge-protected telephone line. Alternatively, the screw terminals (GND, RING, TIP) can be used to connect the COM220 with a phone line via a surge protector.
