Modem đường điện thoại voice kết nối Datalogger Campbell Scientific COM320

Overview

The COM320 is a voice-synthesizer modem that adds speech capability to a 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.

Benefits and Features

  • Allows anyone to call a COM320-equipped site from any phone (including cellular) to receive a verbal report of current site conditions.

  • Enables the datalogger to call you and recite a verbal warning if specified conditions occur.

  • Reports specific conditions or allows selection of information by pressing numbers on a touch-tone telephone

  • Uses voice strings created with CRBasic code

  • Operates over a wide temperature range; extended temperature testing available.

  • Supports communication rates up to 115.2 kbps between modem and logger. (In practice, data transmission through phone lines is generally constrained to 33.6 kbps.)

  • Comes with a speaker that aids troubleshooting in the field

Detailed Description

The COM320 has a CS I/O port, power terminals, screw terminals, and an RJ-11C jack. The datalogger 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 COM320 with a phone line via a surge protector.

The COM320 has a standard word list (see document at right). Campbell Scientific may eventually add more words to the standard list. Customer-requested words for specific applications can also be included; consult the factory for details. The COM320’s sentences are programmed using CRBasic code.
